Maximum number of connections from user+IP exceeded (mail_max_userip_connections)

Bonjour !

A little question :

Can I raise the default value of mail_max_userip_connections in etc/dovecot.conf file ?

The line that reads the value (10) seems to be commented (#), does a default value - unknown of me - already applies ?

Maximum number of IMAP connections allowed for a user from each IP address.

NOTE: The username is compared case-sensitively.

#mail_max_userip_connections = 10

Shall I raise the value and uncomment the line ?

I must restart Dovecot, right ? And something else, also ? Or AM I COMPLETELY WRONG ?

Thank you in advance for your kind help (I am not a paying user)

Howdy,

Can I raise the default value of mail_max_userip_connections in etc/dovecot.conf file ?

Sure! Just uncomment the line you mentioned, and change that to a higher number… 20 perhaps?

And then restart Dovecot, which you can do with this command as root:

/etc/init.d/dovecot restart

Fine, thank you very much for your kind attention and care.

The new way to do this, as of Centos 6.5 / Virtualmin 4.06 is in:

/etc/dovecot/conf.d/20-imap.conf

mail_max_userip_connections = 256

Also, in:

/etc/dovecot/dovecot.conf

Remove imaps and pop3s from the protocols settings (they are deprecated)

protocols = imap pop3
