Majority of email being delivered to customer except one or two

This is a very common issue if you are sending email with multiple invoice or statement attachments.

If you are using IIS 6 Smart Host to relay email:

  • Open Internet Information Services (IIS) 6 Manager
  • Expand the default domain
  • Right click on the [SMTP Virtual Server #1] and select properties
  • Click on the messages tab in increase the following:

Limit message size to (KB): default is 2048 so increase it to 20480

Limit session size to (KB): default is 10340 increase it to at least the size of the Limit message size.

  • ¬†Click OK and resend the email.

If you are sending directly to your SMTP provider check with them to see what the message size limits are because many will set that to 2 MB like Google Applications. The reason for the limit is so the SMTP server does not get bogged down trying to scan the email with spam filter and processing large requests.

Hope this helps.

The consistency check of the snapshot for the Microsoft Exchange transaction log Logs has failed. You should check for possible data corruption in the transaction log that is online.

This problem is related to Backup Exec’s GRT (Granular Recovery Technology) having issue with an Exchange log file. The best method to resolve the issue is to disable GRT within the backup job. Let the backup run and check the logs again after the backup job has run. You should see that the bad log files have been removed and the only log files left are those that were not committed to the Exchange mailbox database.
