I'm having a problem with LMTP not starting.
I know all about the split DNS issues that have been addressed so let me explain first before someone instantly points out that, that is the problem.
I have a split dns so with i do a look up for mail.asdf.com i get 192.168.1.101 back.
All services appear to start however doing a telnet to mail.asdf.com on port 7025 gets a connection refused (even from the same machine). No firewall no selinux. Telnet to ports 25 993 10025 all return banners (sort of).
I've noticed this before on a few work servers. initially when i start the servers (no split dns) that lmtp won't work. We will typically have to shutdown zimbra then start it backup.
Also anytime ltmp won't connect I also get NO banners if I telnet to the POP and IMAP ports (if lmtp allows a connection works i get banners).
I look through the logs but i'm not seeing any errors besides the connection errors about not being able to connect to 192.168.1.101
ps awux returns nothing about lmtp either.
