Postfix “delivery temporarily suspended” sending to google apps

I am getting the following errors when postfix is trying to send mail to my email address which is hosted using google apps:

The DNS for my mail is correctly setup to point to google's mail servers, so why would I be getting these errors?

Best Answer

Can you telnet to ASPMX5.GOOGLEMAIL.com on port 25?

  • telnet ASPMX5.GOOGLEMAIL.com 25

If you get no route to host, you should try the IP address directly:

  • telnet 74.125.157.27 25

If this doesn't work, then you probably have an ISP that is blocking outbound connections to port 25. This is rather common these days to combat spam.

If this is the case you'll have to setup postfix to relay mail through your ISP's SMTP server. See the relayhost configuration parameter.
