Exchange server bandwidth hog
Posted on 2007-10-09
I have a big of a funny one and I am not sure how to further trouble shoot it. I have a Windows Server 2003 enviroment and I have a Front end and Back end Exchange 2003 SP2 setup. Almost every morning for the last few weeks the front end server creates so much outbound smtp traffic that my line to the internet chokes. I have checked the Que during this time and found only a few (maybe 10) messages ready for delivery. The outbound traffic (all on port 25) is active for about 10-15 mins and then it is gone and we do not have a problem for the rest of the day. I have checked the logs and found no problems in the event logs.
