I have an issue whereby clients are unable to connect to Courier Imap
with the error that there are too many connections from their IP. I have
changed the following parameter as follows:
in the imapd file. I restarted courier imap, but still the same problem.
It is particularly apparent with Outlook clients, less so with
Thunderbird. I don't know what that might matter. Particularly strange is
that on one Windows 2000 terminal server using Outlook 2000, for some
clients Outlook has issues, for others it doesn't. Also if I use the
credentials of the clients that have issues and enter them into Outlook
in say my session, it works.
