dovecot - Aug 2013 - Maximum number of connections from user+IP exceeded

All of a sudden I am getting these errors on one of my accounts:

imap-login: Info: Maximum number of connections from user+IP exceeded
(mail_max_userip_connections=10)

It was working fine last night when I went to bed, and is posting these errors
nearly constantly (about one every second) when I checked mail after waking up
this morning.

The account is question is my main account and has a lot of mail, but it is not
the account with the most mailboxes, that one is working fine.

I looked at the documentation on how to increase this setting, but
<http://wiki.dovecot.org/MainConfig> is for 1.x and clicking the
'wiki2" link brings up a mostly blank page with no configuration info
at all. It looks like in dovecot 1.x this would go in an protocol imap block,
but I don't have one of those in my conf.

in case of IMAP 10 is *way* too low!

keep in mind that

* a IMAP client opens one connection *per folder*
* if you have 5 folders and a user with 3 devices (workstation, phone, tablet)
you are done
* if you have a few imap-users behind the same NAT you are done
