Gmail Timing out :
Jul 21 05:17:16 mail postfix/smtp[1758]: connect to ASPMX.L.GOOGLE.com[74.125.25.27]:25: Connection timed out
Jul 21 05:17:17 mail postfix/smtp[1760]: connect to ASPMX.L.GOOGLE.com[74.125.25.27]:25: Connection timed out
Jul 21 05:17:19 mail postfix/smtp[1778]: connect to ASPMX.L.GOOGLE.com[74.125.25.27]:25: Connection timed out

Yahoomail is going through fine :
relay=mx-apac.mail.gm0.yahoodns.net[106.10.166.54]:25
goes through fine.

My firewall and router is open to port 25, 587 and 465

I am very happy with iredmail and want to upgrade my subscription, before that i want to test everything in free version. Please help. Let me know if you need any info.

Thanks in advance

Re: Able to send outbound mail to yahoo on port 25 but gmail is timing out

*) Can you reach aspmx.l.google.com on your server? e.g. ping, host, dig, etc.
*) Can you telnet to Gmail port 25? For example:

$ telnet 74.125.25.27 25
Trying 74.125.25.27...
Connected to pa-in-f27.1e100.net.
Escape character is '^]'.
220 mx.google.com ESMTP g9si14080014pac.68 - gsmtp

Re: Able to send outbound mail to yahoo on port 25 but gmail is timing out

No idea at all. Does your ISP block connection to Gmail?
I think it's better to contact your ISP.
