i instaled zimbra collaboration, it's work fine, but i have one problem.
My relay is blocked, my domains defined, but at certains time a email from a different domain start to send to others, but is not a email from my cleared domains.
I make various test of relay, and always is blocked. I look my logs and the false email is based from my server, 127.0.0.1 !
What can i do to block this?
When i see my queue have 15000 emails stopped and my cpu is 100% and normally my queue have 60 mails and cpu 15%.
Thanks for everyone.
