  1. Arkadios προφανώς αν δεν είναι ο ένας απο τους Mail Servers σου σε RBL list τότε θα πρέπει να δεις τις ρυθμίσεις που έχεις στους Exchange και στα αντίστοινα DNS PTR Records.

    Ποιος απο τους 2 Servers δεν έχει SMTP Reverse DNS Record . Ο Exchange 2000 ή ο 2007? Εχεις τα αντίστοιχα ΜΧ & Α Records σωστά και για τους 2 Exchange ?

    Check τα αρθρα http://technet.microsoft.com/en-us/library/bb124896(EXCHG.80).aspx

    http://support.microsoft.com/kb/300171/en-us

    Πρέπει να δημιουργήσεις και το άλλο PTR Record και να ελέγχεις αν αυτά τα Reverse Records είναι resolved από εξωτερικούς DNS Servers.

    Επίσης στα e-mails που στέλνεις και τελικά δεν πηγαίνουν στο yahoo πρέπει να σου απαντάει o Server με ένα NDR e-mail .Σε ρωτήσαμε ποιο είναι αυτό το NDR e-mail που λαμβάνεις . Δωσε το NDR error message & number. 

    Στο gmail και στο hotmail όταν στέλνεις e-mails πηγαίνουν ή αντιμετωπίζεις το ίδιο πρόβλημα ?  

    Προφάνως πρέπει να δεις το routing που ακολουθούνε τα e-mails σου .

    Τα e-mails τελικά από ποιον servers δρομολογούνται στο yahoo από τον Exchange 2000 ή τον Exchange 2007  ?

    όπως σε ρώτησα και σε προηγούμενο post μου αν κάνεις stopped το SMTP στόν ένα Exchange μπορείς να στείλεις e-mails στο yahoo ? και μου απάντησες


    "Το εκανα με τον παλιο exch αλλα δεν δουλευει μεμωνομενα ο νεος. Χάνω την συνδεση "  To μόνο που μπορώ να πω έιναι να ελεγχεις την δρομολόγηση των e-mails σου και τα Reverse Records .

    Πιστεύω ότι όταν λαμβάνεις e-mails από yahoo τα παίρνεις στον Exchnage που έχεις σωστό PTR & MX Record και είναι resolved & cached σε όλους τους DNS ένω όταν στέλνεις e-mail φεύγει από τον Exchange που έχεις λάθος και καθόλου PTR και γίνεται reject από yahoo.

    Μπορείς να το έλεγχεις αυτό από το Message Tracking του Exchange 2000/2007 και από τα logs του smtp.

    http://technet.microsoft.com/en-us/library/ff829232.aspx

    Microsoft Information Technology (Microsoft IT) maintains a complex Microsoft® Exchange Server environment that consists of several geographic locations and multiple Active Directory® forests. There are 16 data centers, four of which host Exchange servers, to support more than 515 office locations in 102 countries with more than 180,000 users. These users include managers, employees, contractors, business partners, and vendors. Microsoft IT transitioned this environment to Exchange Server 2010 in less than seven months by taking advantage of its growing automation infrastructure and the enhanced deployment features available in Microsoft Exchange Server 2010, in combination with proven planning, design, and deployment methodologies

  9. Download System Center Essentials 2010 Resource Kit

    The System Center Essentials Resource Kit includes:

    Essentials Server Migration Advisor

    Published Software Certificate Update Tool

    Setup Log Parser

    Maintenance Mode Management Pack

    Computer Group Repair Tool

    Essentials Server Cleanup Tool


    Essentials Server Migration Advisor
    You can use this tool to move an Essentials 2010 management server installation to a different server. The tool backs up the installation on the source server and restores it on the target server.

    Published Software Certificate Update Tool
    The published software certificate update tool removes the existing software publishing certificate from the Essentials 2010 or Essentials 2007 management server and all managed computers, generates a new certificate, deploys the certificate to managed computers, and signs all locally published content with the new certificate.

    Setup Log Parser
    When you install System Center Essentials 2010, Setup creates SCESetupWizard.log and a set of related log files, depending on the features you chose to install, such as SQL Server, Reporting, and Virtualization Management. If installation fails, you can use this tool to get an easy-to-read-report that contains enough information to determine if the installation was successful and to highlight any issues.

    Maintenance Mode Management Pack
    System Center Essentials 2010 maintenance mode does not provide a way to schedule the maintenance mode start time to begin at a future time. Use this tool if you want to schedule a group of computers to enter maintenance mode at a fixed time in the future. For example, you may want to schedule a group of computers to be in maintenance mode every Friday and Saturday night at 11:00PM for a duration of three hours.

    Computer Group Repair Tool
    The computer group repair tool identifies and repairs broken relationships between System Center Operations Manager computer groups and their corresponding Windows Server Update Service (WSUS) computer groups.

    Essentials Server Cleanup Tool
    After an installation failure, you can run the Essentials Server Cleanup Tool to clean out files left over from the failed installation and restore the computer to a clear, preinstallation state so that you can start the installation over again. Note that the tool removes existing Windows Server Update Services (WSUS) certificates from the computer.

  12. Σε ευχαριστώ i-away  για την επισήμανση για το firewall -  το ότι είναι σε black lists είναι το ποιο πιθανόν .

    Αλλά αν κάνει stopped το spam firewall και στέλνει τότε e-mail σε yahoo ? θα επρεπε να στέλνει αν ήταν σε black list ?

    @arkadios δώσε μας περισσότερες πληροφορίες

    Εχεις κάποια NDR - καποια non deriverable errors - logs που σε ρώτησα και σε προηγούμενο post ?

    Εχεις τσεκάρει αν ο Mail Server σου είναι σε κάποια Spam Black List ? 

  13. Στην περίπτωση αυτή που αντιμετωπίζεις το πρόβλημα μη αποστολής e-mail στο Yahoo μπορεί να οφείλετε στο ότι οι Exchange Servers σου και οι IPs αυτων είναι blocked από RBL list ή σε κάποιο άλλο

    παράγοντα ( ISA , Spam Content Filtering κτλ )

    Για να επιλύσεις το πρόβλημα ένα troubleshooting tip είναι να περιορίσεις τους παράγοντες που μπορούν να αποτελέσουν αίτια του προβλήματος:

    - Ελέγχεις αρχικά αν οι Ips των Servers είναι σε RBL lists

    - Ελέγχεις ξανά τα Reverse Dns Records .Οι DNS οι εξωτερικοί τα αναγνωρίζουν ?

    - Περιορίζεις το πρόβλημα πάνω στον Exchange - Δεν προσπαθείς να προσωμοιώσεις το πρόβλημα απο τον Client . Θέλεις αρχικά να στείλεις e-mail στο Yahoo αλλα πάνω από Exchange

    - Stopped τον ISA μπορείς να στείλεις e-mail ? οχι --->

    - Stopped το Spam firewall μπορείς να στείλεις e-mail ? όχι --->

    - Stopped το Content Filtering μπορείς να στείλεις e-mail ? όχι --->

    - Stopped το ένα Exchange SMTP  μπορείς να στείλεις e-mail ?

  14. Αρχικά θα σε παρακαλούσα να γίνεις λίγο ποιο σαφής - περιεκτικός όσο αφορά την περιγραφή της υποδομής - τοπολογίας του δικτύου σου για να
    την κατανοήσουμε όλοι και να μπορέσουμε να σε βοηθήσουμε.

    Ανακεφαλαιώνω διόρθωσε με αν κάνω κάποιο λάθος.Εχεις τα εξής  :

    -1 Domain

    - 2 Exchange 2007 και 2000 , θέλεις να καταργήσεις τον 2o

    - έχεις baracuda αυτό ειναι spam firewall filter ?

    - έχεις content filtering software

    -  έχεις Isa για  proxy 

    - έχεις 3 Ips που στους Exchange και σε ποιά service ?

    - έχεις τι DNS Reverse records και που ?Σε ποιο από τα 2 Dns reverse records έχεις πρόβλημα ?  μην  μας δώσεις τα Real Dns Names του Exchange σου- Εξήγησε μας την δομη τον Dns records  με μη πραγματικά DNS names πχ exch1.domain.com , exch2.domain.com κτλ

    - Μπορεις να λάβεις e-mail από  Yahoo αλλά δεν μπορείς να στείλεις . Αυτό το πρόβλημα το έχουν όλοι οι χρήστες οι καποιοι μεμονωμένοι ?

    - Οι SMTP IPs που είναι ενεργοποιημένες στους Mail Servers σου έχεις διασταυρώσει αν είναι Blocked απο Spam Lists και κατ'επέκταση απο Yahoo Mail Servers με αποτέλεσμα να μην δέχονται το Smtp Connection σου ? Tι error λαμβάνεις στα Underiverables outgoing e-mails ?

    - Εχεις ελέγχει αν οι Exchange Servers σου είναι Open Relay ?


     

  15. Θα προσπαθήσω και εγώ να βοηθήσω ...

    Αρχικά το office xp δεν υποστηρίζετε ως client στον Exchange 2010 see

    http://technet.microsoft.com/en-us/library/aa996719.aspx

    Exchange 2010 supports the following versions of Microsoft Office Outlook and Microsoft Entourage for Mac:

    Outlook 2010 Outlook 2007 Outlook 2003 Entourage 2008 for Mac, Web Services Edition

    Υπάρχει και ένα αρθρο με ένα παρόμοιο πρόβλημα http://social.technet.microsoft.com/Forums/en-US/exchangesvrclients/thread/46ad5d38-c7a2-4de9-872a-7c6e9ee8c2be

    Θα συμφωνήσω και εγώ με την άποψη του Παναγιώτη όσο αφορά το codepage.

    Το πρόβλημα μάλλον κατά την άποψη μου είναι στο Support που παρέχει το Outlook 2002/xp σε Exchange Accounts όσο αφορά το Unicode or non Unicode Mode που λειτουργεί.

    Δείτε τα παρακάτω άρθρα όσο αφορά αυτό το πρόβλημα :

    Unicode support for multilanguage data in Outlook

    Impact of running in non-Unicode mode on the Exchange server

    Benefits of running in Unicode mode on the Exchange server

    Troubleshoot Unicode-related problems

    Οπως αναφέρουν και τα άρθρα

    - Earlier versions of Outlook provided support for multilingual Unicode data in the body of Outlook items. However, Outlook data, such as the To and Subject lines of messages and the ContactName and BusinessTelephoneNumber properties of contact items, were limited to characters defined by your system code page. This limitation is no longer the case in Microsoft Office Outlook 2003 and Microsoft Office Outlook 2007, provided Outlook is running in Unicode mode with an Exchange account.

    - Since Microsoft Outlook 2000, the body of Outlook items (item: An item is the basic element that holds information in Outlook (similar to a file in other programs). Items include e-mail messages, appointments, contacts, tasks, journal entries, notes, posted items, and documents.) is Unicode, and the body of the item can be read irrespective of the language in which the item was created. However, all the other item properties such as the To, Location, and Subject lines of messages and meeting items and the ContactName and BusinessTelephoneNumber properties of contact items will be unintelligible in versions earlier than Outlook 2003

    Το πρόβλημα εμφανίζετε και σε offline folders και σε online folders στο Outloox xp ή μονο σε offline folders ?

    Επίσης επειδή το πρόβλημα ειναι με το Unicode Mode του Outlook θα σου πρότεινα αρχικά να ελέγχεις στο Windows 2008 που έχεις εγκαταστήσει τον Exchange 2010 τι Language έχεις επιλέξει στο Control Panel - Regional and Language Options - Administrative - Language for non-Unicode Programs .Εχεις Greek στο Current Language for non-Unicode Programs?

    Επίσης τον ίδιο έλεγχο πρέπει να κάνεις και στο Client Vista/7/XP για default languange for non-Unicode programs.Εχεις και εκεί Greek Default ?

  16. Blackman check το PM μου

    Βλέπω και έγω timeouts 2 seconds σε Emporiki .Φαινεται ότι έχουν DNS records με Round Robin και καθυστερεί να σου απαντήσει και παίρνεις στο πρώτο recursive query timeout 2 seconds.

    Για να μην έχω timeout εγώ έκανα την παρακάτω διαδικασία

    1. Εβαλα forwarder στον DNS του Active Directory τον DNS του ISP Provider

    2. Αφησα στο tab forwarders το Number of seconds before forward queries time out : 5 seconds ( default value)

    3. Τότε η απάντηση που πήρα απο το DNS Internal του AD ήταν χωρίς timeout

    nslookup mrelay.lb.emporiki.gr
    Server:  localhost
    Address:  127.0.0.1

    Non-authoritative answer:
    Name:    mrelay.lb.emporiki.gr
    Addresses:  212.251.47.205, 91.138.160.77

  17. Windows 7 Momentum Continues: 175 Million Licenses Sold

    Microsoft Reports Record Fourth-Quarter Results

    Today is earnings day and Windows continues to have a strong showing. We announced a new milestone in Windows 7 sales - 175 million copies. This continues our record breaking pace of more than 7 copies sold per second. And as of today – Windows 7 is now running on more than 16% of all PCs worldwide. It's exciting to see this kind of response from customers who have helped make Windows 7 the fastest selling operating system in history. We are also seeing some strong momentum with businesses for Windows 7. The PC “refresh cycle” for businesses has accelerated and we recorded the second straight quarter of double digital business license growth. And with Internet Explorer, IE8 is now the fastest growing and most popular web browser in the market and we have IE9 coming!

    This strong momentum isn't limited to Microsoft  - in fact we're seeing strong growth across the tech industry. Last week we highlighted a recent IDC press release that illustrated the growth of the global PC market - more than 22.4% year-over-year for the second quarter of 2010. Intel reported its best quarter ever with second quarter revenue up 34% year-over-year. And AMD reported a whopping 40% growth year-over-year in its earnings release, due to record sales of their chips for notebook computers. It's great to see this kind of growth across the PC ecosystem and we're pleased to be part of this growth with Windows 7.

  18. Να σας συγχαρώ και εγώ για την συγκεκριμένη πρωτοβουλία και να ευχηθώ να υπάρξουν και άλλες τέτοιες ενέργειες στο μέλλον.

    Θα συμφωνήσω και εγώ με τον Ανδρέα, οτι ο λόγος που συμμετέχουμε όλοι στο autoexec forum είναι για να προσφέρουμε αφιλοκερδώς βοήθεια με όποιο τρόπο μπορούμε

    στους συναδέλφους του IT Community και αυτό γίνετε ποιο επιτακτικό στους δύσκολους καιρούς που βιώνουμε.
