connection limit reached

Krillian

Hi,

I have the following setup:

domain1 not mailcow
domain 2 mailcow

I am forwarding all emails from domain1 to domain2 but I get the following error:

R=external_mail_router T=remote_smtp defer (-53): connection limit reached for all hosts for '

Is there a way to remove the connection limit, or at least increase it?

Thank you very much in advance!

Any ideas?

Hi,

That’s not a mailcow message. Looks like the source prints that message.

Hi,

In any case is there a way to disable the connection limit as messages aren’t being forwarded to mailcow domain whereas they forward fine to a non mailcow one…
