We are using Symantec Messaging Gateway running on 10.5.2 with a CC and scanner. We mainly use this server for Outbound. We are facing issue in delivering outbound emails when users are sending bulk mails. Mails are getting stuck in delivery queue for few mins to couple of hours and rest of the emails are delivered with delay. This issue is mainly happening when bulk emais have large attachments. We are unable to find the root cause of this issue even we worked with symantec techinicians.
I wanted to know if there any possiblity to exempt a mail from Virus scanning based on source IP / Any string or flag in the message / specific sender? or How can we know the capacity of the server to handle the mails like how much data it can handle per hour like 8 GB or 10 Gb etc. Below are our server details.

Processor Type : Intel(R) Xeon(R) CPU E5540 @ 2.53Ghz (2)
