mail_max_userip_connections per remote IP not working

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.

Subject: 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
