Hi Tom,

   The setting mail_max_userip_connections is per IP.

from 20-imap.conf (version 2.0.13, the version we are running)

# 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

I am going to assume he has a different IP for each device, in this case that would allow up to 30 connections.

You need to  post your 'doveconf -n' output!

Cheers,
Paul
