A couple of days ago the deferred queue started to grow.
Checking the /var/log/zimbra.log I found several records like this:
Code:
mail postfix/smtp[14875]: D15641A802A4: to=<info@domain.tld>, relay=none, delay=1198, delays=1198/0.02/0/0, dsn=4.4.1, status=deferred (connect to mail.server.com[127.0.0.1]: Connection refused)
mail postfix/qmgr[8273]: EE5371A80297: to=<info@domain.tld>, relay=none, delay=1200, delays=1199/0.48/0/0, dsn=4.3.0, status=deferred (mail transport unavailable)
*All domain names and public ips replaced for privacy
I know these mails origins from another box with smtp mail function sent using a standard form.
I made sure I can telnet to port 25 on localhost and send mail and I've read others posts for hours and hours and I cant locate the problem.
Code:
postconf mynetworks
mynetworks = 127.0.0.0/8 10.10.10.64/26
10.10.10.64 is not the servers IP but instead the networks broadcast.
Code:
cat /etc/resolv.conf
options rotate
options timeout:3
search mail.server.com
nameserver 10.10.10.119
10.10.10.119 is the mail servers IP. I'm also running BIND and named is up and running.
Code:
cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
10.10.10.119 mail.server.com mail
