Where to set the maximum number of concurrent smtp connectios?

Where can you alter the maximum number of concurrent smtp connections when logging in to check for waiting mail…?

The current default appears to be 10 as 10 connect straight away while the rest are queued and then connected as the other ones complete.

Many thanks


It sounds like what you’re interested is the Postfix “smtpd_client_connection_count_limit” param:


You can set that up in /etc/postfix/main.cf.

There’s probably also a place to set the same parameter in the Virtualmin GUI, in Webmin -> Servers -> Postfix, but I’m not immediately seeing it :slight_smile:


Thanks Eric

Sounds like I was looking in the right place… but I couldn’t find it there either…

All the best
