Big problem with Sendmail

[godzilla]

Hello from this morning, without touching NOTHING on a working sendmail freeBSD server we have this problem:

We can receive mail local and from the inet.
But we can't send !!!

The log shows the following :

We are not banned in the CBL black list.

What is happening ? Thanks !

Is mail coming in from the outside? Has your ISP decided to block port 25 traffic? Are you on a dynmiac/residential type of connection?

By the way: please edit or remove that piece of logfile. You're opening these addresses up to spam harvesting.

[godzilla]

No, It is mail being sent. There's a problem of connection timeout with the domain names of the mail relay. Connections are being made but then timeout !

It doesn't look like a Sendmail problem to me, just a network/filtering problem. I'd suggest contacting your ISP or upstream connectivity provider, or using their mail relay host if they have one.

[godzilla]

I just called but our connection is a plain normal one, not enterprise. So . . . the support is crap.

[DutchDaemon]

Can you perform a simple 'telnet someserver 25' to some of the servers mentioned in your maillog? Just to see if they're actually reachable from your mailserver.

[godzilla]

Done DutchD ! We changed the GW to another router attached to another ISP connection and the queue is being sent. Probably a crappy tech has gone wild on the other side.

Thank you a lot.

[godzilla]

How do you set up the mail relay of the provider ? We use webmin to control and configure Sendmail . . . is there a way through the web interface to configure it ?

Thanks dutch !

Look for a setting called "Smart Host".
