Another issue with this problem is that it should be totally hidden
from the user. I've seen this happening with Thunderbird which, if I
remember correctly, defaults to a maximum of five connections and even
this often conflicts with ISP (and other) IMAP setups. The result is
an error message which 99% of users can't understand and can't fix.
The MUA and the IMAP server should 'negotiate' a mutually acceptable
number of ports.
