Release 5.0.7_GA_2444.RHEL4_64_20080626023050 RHEL4_64 FOSS edition
Last week our ISP blocked us on their SMTP server for SPAM abuse. They said the same message was sent over 700 times. The forwarded a copy to me and it originated from one of our staff through their zimbra account. I confirmed they only sent it once so assumed it was a one off glitch with Zimbra. Our internet connection was very sluggish while this was going on.
We have been using zimbra for 18 months and this is the first time we've had this problem. We recently upgraded the server hardware and zimbra version about 3 months ago.
I came in this morning...once again the internet is sluggish. So I stopped postifx on the zimbra server and voila the internet is fine.
Now the problem is I don't how to stop postfix from sending this continual email, if I start postfix again, within a few minutes it is resending.
postqueue -p says the queue is empty
please help me find this rogue message!
EDIT: stopping postfix has not fixed the problem...the emails are still continually sending. Where do outbound emails sit on zimbra?
