Do you mean SMTP?

Under troubleshooting options, you can control the logging level.  Sounds like yours is set to Detailed.

The size is determined by logging level and transaction volume.    Maybe you are getting spammed and the log reflects high transaction rates.

Hello, 

This sounds like unusual activity for your SMTP sessions. I would recommend reviewing the log with a large-file viewer to see what was going on and try to prevent it in the future. You can also adjust the logging while you get this resolved. This log is used to track down a lot of issues and is set to "Detailed" by default because of this. 

Thank you
