Hi-

In the last few days I noticed that email I send to my gmail
account from my postfix server never makes it to gmail.

I havent touched the config in a few weeks so nothing should
have changed from when it worked. My server relays through
my ISP. My domain DNS records are working fine and I checked
for blacklisting and Im not blacklisted. The log file shows
250 sent.

I tried commenting out the relay_host line so it would go
directly to gmail and I got:

Apr 5 22:33:01 myserver postfix/smtp[27160]: connect to alt3.gmail-smtp-in.l.google.com[209.85.218.17]:25: Connection timed out
Apr 5 22:33:31 myserver postfix/smtp[27160]: connect to alt4.gmail-smtp-in.l.google.com[74.125.157.27]:25: Connection timed out
Apr 5 22:33:31 myserver postfix/smtp[27160]: 2372872E0D7: to=<myemail(a)gmail.com>, relay=none, delay=660, delays=510/0.02/150/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[74.125.157.27]:25: Connection timed out)

It just keeps repeating this after the retry period (Im assuming).

Anyone have any idea what to check next or why this
might be happening?

Thanks,
Jeff

Something (likely a firewall) is prohibiting you from directly
connecting to the gmail.com MX; I am able to connect to it just fine
from here. If you typically send mail via a relayhost, continue doing
so, and ask the admins of said relayhost to help troubleshoot your
problem with delivery to gmail. This is not a Postfix issue.

Jeff,

It's just what Sahil said. Your ISP is blocking outbound SMTP, at least to gmail, so you will only be able relay through your ISP.

Why not just use port 587? You will have to configure SASL, etc;
however, once done it should work just fine. That is how I do it.

Jerry,

For me that wasn't a workable solution, since many of the recipients, of messages sent from my server, are on servers that use technology such as the zen spamhaus list, which blocks email sent from dynamic ranges. This ends up blocking my mail anyway, so I just relay.
