Postfix - status=deferred; Connection timed out

[qwertybrg]

Hy,

I followed this (Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 7.10)) tutorial for an email server. I did stept by step, with no errors. The only changes I have made are regarding ip's and domains.

The server works fine, I can receive email, I also can send emails but only for the users of my domains. If i try to sent a message to someone@gmail.com i get this error status=deferred (delivery temporarily suspended: connect to gsmtp183.google.com[64.233.183.27]: Connection timed out).

The server is behind a router, and i have forwarded port 25 and 110, 143 to the server. Also to mention that I have tested another email server which works fine on the same connection, so the provider didn't block port 25.

i'll give you the main.conf of teh server and some lines from the log:

main.conf:

Thanks in advance and Happy New Year to all of you

If your internet connection has a dynamic IP address, then it will be blocked by most email providers like google or hotmail. You should consider to relay your emails trogh the smtp server of your internet provider instead.

Hy,
thanks for the quick answer.

I have a static IP.

Maybe this can help. I found this error in the postfix queue list from postqueue -p

3101 Fri Dec 28 15:52:02 admin@domain.ro
(Host or domain name not found. Name service error for name=localhost type=A: Host not found)
********@gmail.com

I have a similar error for each mail that i tried to sent.

Please advise......

Thank you in advance

Please check if your server is blacklisted: http://www.mxtoolbox.com/blacklists.aspx

What's in /etc/hosts?

[qwertybrg]

Here is my /etc/hosts

127.0.0.1 localhost.localdomain localhost
192.168.123.118 mail.domain.ro mail

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

The server is behind a DSL router, in which i have set as a "virtual server" the address of the actual server.

Thank you

Please try this:

127.0.0.1 localhost.localdomain localhost
192.168.123.118 mail.domain.ro mail domain.ro

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Hi All
I have same problem as You "running PostFix Mail Server behind router "
I can receive mail from outside but I can`t send them out I read lot of forums and lot web sides I did not found solution for this problem
but I know for sure this is because of router
If I connect server directly to DSL modem everything is working perfectly
but not if is behind router even I open port 25 to mail server
do anybody know haw to set up PostFix do deal with this, or any other suggestion?
Thanks Chris.
