Arvi, if you can’t resolve the domain, some things to check:

1) Is there a difference between the nameservers you are seeing in /etc/resolv.conf and what appears in System Preferences > Network for the DNS Server? For that matter, /var/run/resolv.conf and /private/etc/resolv.conf should all match too.

2) Maybe it’s a problem with lookupd. You can restart it with “sudo dscacheutil -flushcache”.

3) Have you installed anything to block ports like PeerGuardian, Little Snitch or done anything firewallish?

4) Is the behavior different at home vs. school or a corporate network? Do you run your own DNS?

5) Anything else in /var/log/mail.log that looks interesting?

Thanks Man. I got it working for weeks but suddenly I am receiving this error.

(delivery temporarily suspended: Host or domain name not found. Name service error for name=smtp.gmail.com type=MX: Host not found, try again)

I didn’t do anything…once I got it working what I do is just sudo postfix start and sudo postfix stop when I’m not using it. What could have happened?

Thanks.

Similar problem to dob, but no TLS issue. Simply:

-Queue ID- –Size– —-Arrival Time—- -Sender/Recipient——-
8F5E52690185F* 317 Thu Oct 8 11:51:37 yaniv@beethoven.localhost
myname@me.com

I *can* access smtp.gmail.com on port 587 with telnet, and interact with the SMTP server there; nothing is blocking the path.

Ideas?

This worked brilliantly for me once I removed the underscores from your “_postfix” and “_postdrop” in the following main.conf lines. Were these just typos, or are they required in some cases?

# Minimum Postfix-specific configurations.
mydomain_fallback = localhost
mail_owner = postfix
setgid_group = postdrop
relayhost=smtp.gmail.com:587

Sadly, gmail seems to be refusing my tls connection:

my-macbook-pro:serp dball$ mailq
-Queue ID- –Size– —-Arrival Time—- -Sender/Recipient——-
C41B3C100D0 378 Thu Sep 17 13:16:48 dball@my-macbook-pro.local
(TLS is required, but was not offered by host alt4.gmail-smtp-in.l.google.com[209.85.135.114])
my.username@gmail.com

Any suggestions?
