Cannot send mail with postfix


I'm trying to send through the Mac terminal:

date | mail -s testing test@gmail.com

In mail.log I get the following error:

"Jul 19 10:19:17 oris-imac.home postfix/error[707]: 165009630728: to=<test@gmail.com>, relay=none, delay=31, delays=0.61/31/0/0, dsn=4.4.3, status=deferred (delivery temporarily suspended: Host or domain name not found. Name service error for name=smtp.gmail.com type=MX: Host not found, try again)
Jul 19 10:19:46 oris-imac.home postfix/master[682]: master exit time has arrived"

I looked for a solution online but couldn't find any one that was useful for me, but I guess it's a DNS issue.

Anyone know what can I do to solve this?

Where did you look? What have you tried? Looks like a DNS problem but could be anything.

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?
Info and things to do and check here and here. Post some output of the commands you ran.

While I'm testing the points you brought up (Thanks!), I'll add that I changed system preferences -> network -> advanced -> DNS to google's public DNS server and it now works.

Anything I need to do to make it work without it?
