[SOLVED] mails sent by undeliverable to gmail yahoo or else

[khalilamar]

Hi Tech Folks

I've had zimbra running as a charm and one day, our ISP made us change the IP numbers.
I did so on my zimbra server and re-run the config so that /opt/zimbra/config-- and config.#### are fine.

after having that changed
zimbra can deliver emails to itself and within the same domain.
but nothing outside such as gmail or else.

and we're not blacklisted or something...

it's really weird

here's an example from /var/log/messages

reverse lookup is fine (agora.ras.ma. <-> 196.2.85.203)
hostname is fine ( agora.ras.ma )
config files inside /opt/zimbra are fine

version of zimbra is as follows
Release 5.0.4_GA_2101.RHEL4_20080321155827 CentOS4

I am not tempted to upgrade now. :X

any input will be highly appreciated.

Thanks in advance.

Thanks for your help

the logs above are not complete because I based it on /var/log/messages
and the status of all the services are green

I played with postqueue -p and postqueue -f

changed the MTA to my ISP SMTP, by doing the trick

zmprov ms agora.ras.ma zimbraMtaRelayHost smtp.mtds.com:25

postfix reload ; postqueue -f ; postqueue -p

and the held emails went through like missiles.

postfix was holding the emails.
the reason is still unclear. it wasn't looping to itself, no. but the connexion to hotmail/gmail and else were timing-out. the other server was ignoring my zimbra.

telneting from zimbra server to smtp of gmail on port 25 gives me a connexion OK. So I assume they're doing the handshake and the HELO.

is it gmail being restrictive? probably.

are my dns and reverse-dns wrong ? I don't think so.

I'd like to return to my original setting where the postfix of zimbra was the actual sender.

otherwise I will wait until summer and install a fresh server 6.0.x on fedora or centos and get rid of this problem.

but at least zmprov ms on the Mta did the trick.

I've checked /var/log/maillog, /var/log/zimbra.log and /var/log/messages

Do you think I should check somewhere else ?

Based on the two lines below
it is saying that using the zimbra smtp, connexion is interrupted by the mail server destination.
If I switch to my isp smtp, it gets delivered.

zimbra.log:Dec 16 19:01:28 agora postfix/smtp[1033]: E15B43D1889: to=<khalilamar@sympatico.ca>, relay=mxmta.sympatico.ca[67.69.240.23]:25, delay=3405, delays=3359/0.04/45/0, dsn=4.4.2, status=deferred (lost connection with mxmta.sympatico.ca[67.69.240.23] while receiving the initial server greeting)
zimbra.log:Dec 16 19:10:10 agora postfix/smtp[5680]: 662E43D174E: to=<khalilamar@sympatico.ca>, relay=smtp.mtds.com[196.2.80.6]:25, delay=5632, delays=5631/0.03/0.05/0.37, dsn=2.0.0, status=sent (250 Ok: queued as 70B9073C0AD)

I think I may know where is the conflict.
DNS updates don't reach some dns servers. I need to contact my isp (he's my secondary dns) to update the reverse name.

# nslookup

> exit

at the end it's not zimbra's fault, even if it's an old release

Is this a complete set of log events for a failed attempt? All this is showing is that the message passed through the antivirus / antispam check (amavisd). I believe you should also see stuff in the logs where it actually tries to send the message to the remote email server(s).

Are you sure all your Zimbra services are running? What does the output of 'zmcontrol status' (run as Zimbra user) show?
