I have an issue with some emails with attachments not being delivered. I have made sure there are no restrictions on the AV softwares etc and for information simple emails without attachments go through fine.
Example: 1/2 dozen lines of text with 1MB attachment sent to two users. Email without attachment gets through. After checking mesage logging the log reports as follows:
10/3/2008 7.47 AM SMTP: Message submitted to Advanced Queuing
10/3/2008 7.47 AM SMTP: Started Message Submission to Advanced Queue
10/3/2008 7.47 AM SMTP: Message Submitted To Categorizer
Thats it! - it ends there and doesnt process to Que for routing/Que for local delivery etc etc
Not sure whats happening with the email. Any help would be great.
