Mail temporary deferred after zimbra migration
i must migrate from an older server to newer, this server isn't into a lan (have a public ip on eth0) and serves several services (web, dns, mail, ecc ecc)
we are speaking about a debian lenny server (both of them)
i did the following:
install zcs on the new server
copy the entire /opt/zimbra from the older to the newer
run again setup.sh to perform the upgrade.
Everything seems work fine but the local delivery fails with ALL of the incoming emails:
Nov 20 11:52:54 kratos postfix/lmtp: 6859B165B338: to=<firstname.lastname@example.org>, relay=mail.ilportalinux.it[18.104.22.168]:7025, delay=44570, delays=44570/0.34/0/0.05, dsn=4.0.0, status=deferred (host mail.ilportalinux.it[22.214.171.124] said: 451 4.0.0 Temporary message delivery failure try again (in reply to end of DATA command))
"mail.ilportalinux.it" is being resolved correctly, no logs on mailboxd.log, no mails delivered, nothing changed between the older server and the newer, also in the older server all is working perfectly.
I can telnet successfully to the 7025 even using FQDN, public ip address and local loopback ip address. No firewall installed.
Please someone could help me?
