Computer software doesn't just "suddenly" break. You need to find out what
was "suddenly" changed on your system in order to be able to repair it.

Could it be that you updated or changed your IMAP server?

I can't help you, but maybe someone else on this list can. However, I'd
like to take this opportunity to suggest that you upgrade your
SquirrelMail installation to 1.4.13 and reconfigure it from scratch. 1.4.2
was released 2003-10-01, which is more than four years ago, and contains
known security holes that can be exploited. Who knows, maybe upgrading
will solve your problem as well?

Sincerely,
Fredrik
