Only able to send 2 emails at a time to a domain

[jmurfin]

Hi,

A specific domain will apparently only allow two emails at a time sent to their domain? I've looked at the logs, and it's all clean, the communication ends like there was only two to send, but there are 14 in the queue! The only way I can send the whole bunch is to stop/restart SMTP and then they all fly through - only to queue up again the next time.

Any ideas?

You can limit the number of messages your system passes per connection. On the SMTP virtual server on the "messages" tab, set the "number of messages per connection" to 2.

Thanks for the response! I will certainly try that. I have always kept the default setting, but I guess I have to see what the impact is on the system with extra connections. My bet is that it'll be minimal, as we don't send very many to the same domain at once.

Thanks again!
