I have an install of centos 5.2 x64 with zimbra 5.0.14, I ran in to issues with almost the exact same errors. Using this and a couple of similar threads I found that when installing fetchmail, it also installs exim... exim is what was hosing up my MTA. I found it after pulling off zimbra and then checking what was on port 25.
Thanks for the help, just wanted to share a specific because the issue was kind of wonky. |
