dovecot - Apr 2021 - mail_max_userip_connections per remote IP not working

Hi,

I'm tryng to set a specific mail_max_userip_connections for a remote IP 
(webmail IMAP software), but it seems not working:

remote 1.2.3.4 {
 ? protocol imap {
 ??? mail_max_userip_connections = 100
 ? }
}

and also this isn't working

remote 1.2.3.4 {
 ??? mail_max_userip_connections = 100
}

I insert it at the end of 20-imap.conf file.

Is something wrong or is not supported?

I'm running dovecot 2.3.14.

Thanks

Alessio,

This isn't supported.
You can only set the same max connection for all userips.

protocol imap {
  mail_max_userip_connections = 100
}

The conf above will act :
 - 1.2.3.4's max connections will be set to 100 when using imap connection.
 - 1.2.3.5's max connections will be set to 100 when using imap connection.
 - and so on. Every connection to imap will have max connection limit, 100.

If you want to limit max connections only for a specific ip, you might want to
do that on your firewall.
