Description Robert 2011-03-10 22:38:09 CET
Once a week or so my POP3 server times out during authentication. When this happens, claws will ask me for my password again.  The error message for a bad password is different, so it seems like this shouldn't be necessary.

[16:09:42] POP3< -ERR Connect attempt failed: server may be down or too busy to respond.

Bad password:
[16:35:24] POP3< -ERR Logon failure: unknown user name or bad password.

patch for non-password auth errors

I've recently started using DavMail to interface with an Exchange server via EWS, and the EWS server is a little flaky. So sometimes I get "EWS end point not available". This causes the same issue as the connect attempt failure - I get prompted for my password on the next attempt.  This happens much more frequently than the previous error, which finally drove me to fix it.

The attached patch adds a hardcoded list of string which are compared against the ERR string during authentication. If the error matches a string in the list, the error code is changed from PS_AUTHFAIL to PS_ERROR. The error is logged, but the user will not be prompted for their password on the next connection attempt.

Patch is against 3.8.0.

updated patch

A new non-error error popped up today. I don't want to have to rebuild claws every time this happens, so I rewrote the patch to read a config file for non-password errors instead of hardcoding them.
