Hello,
have a Zimbra Ver2 Mail server setup behind a firewall.
Mail keeps getting stuck in the postfix mail queue
The server is on a private IP address the firewall is on a public ip address.
The following ports are forwarded to the private ip,
Zimbra_Admin 7071
Zimbra_HTTP 80
Zimbra_HTTPS 443
Zimbra_SMTP 25
Zimbra_SSH 22
Zimbra_IMAP 143
Zimbra_IMAPS 993
Zimbra_POPS 995
Zimbra_POP 110
Zimbra_LDAP 389
Zimbra_Contr 7777
Zimbra_?? 7025
The /etc/hosts file has
127.0.0.1 for the ip address of the domain name
when the server is first started, everything works as expected.
after a couple hours running, the local mail stops getting delivered, with this error message in the zimbra.log
status=deferred (connect to domain.com[123.123publicip]: read timeout)
'zmcontrol status' shows everything as running.
server shows 200~300 mb free memory
when I try to do a
postqueue -f (Flush queue) get the same timeout errors.
Only way to fix it is to do a
zmcontrol stop,
zmcontrol start, then
postqueue -f this then delivers the mails
I don't understand why this is happening.
