REALLY NEED HELP NOW!

[Nick Cockinos]

Hi Toasters,

Further to my post https://www.tnpi.net/support/forums/index.php/topic,812.0.html...

Everything looked good. but for some reason, during the night the NEW server developed the same problem. Port 25 shows up as filtered and SMTP connections are rejected from everywhere. No mail gets into the server an dnone goes out!

A restart of the server got it going again, but we can't keep going this way.

Can someone please give me an idea of where to look. I've scoured through logs and the forum. The nearest i can find to our problem is this post by Logicx: https://www.tnpi.net/support/forums/index.php/topic,154.0.html.

then the smtpd comes along, reads tcp.smtp.cdb at each run (defined in the service/run file for smtpd), and it'll stop our toaster from accepting any further emails for 24 hours from that sending host; so that they hopefully resolve their virus issue.

This will stop me from getting more notifcation emails about the same host for atleast 24 hours.

.

Guys, I'm stumped!! Any ideas, please let me know.

WHACK!!!! It hits you!

Max SMTP Connections! currently set to 20 which I guess is reasonable. But! If I have one customer who is getting hammered with spam then that's going to impact on the entire server, isn't it?!

So if I double the connections (or triple) I have less risk of the server crashing (and increase SMTP memory too).

It also explains why the original server miraculously came back to life! DOH! i wish I thought of this before pulling out my hair!!!

Anyway thanks to those who took the time to look at my post...
