[Dovecot] Meaning of mail_max_userip_connections?

[Harald Strack]

Hi,

I set mail_max_userip_connections in our IMAP configuration to 

mail_max_userip_connections = 10

to allow users 10 parallel connections.  It seems that this also limits
the amount of parallel connections from one IP but different users?! 

Our users mostly accessing the IMAP server by a webmailer or  proxies.
Thus, all users (>10000) come from only 5 different IP. However, I got a
lot of complaints about denied connections after setting
mail_max_userip_connections = 10.

Am I right with the meaning of this parameter?

Thanks in advance

Harry
