Re: pop3 password not working anymore?

[Danny Sauer <cloudmaster@cloudmaster.com>]

Does *sendmail* actually reject your password, or is it tha tyou can't 
log in using POP3?  In the more likely case that you can't log in using 
your mail client to check your mail, I'll make the assumption that 
you're using a system that uses PAM auth.

Probably the easiest way to make it work is to find another thing that 
lets you log in - like ssh or the console.  If you can log in at the 
console, for example, look at /etc/pam.d/login and /etc/pam.d/pop3d (or 
a name similar to that depending on your system, you get the idea) and 
see what's different.  PAM (usually) uses a different file for each 
service with the name of that service, so ssh uses /etc/pam.d/ssh, pop3d 
uses /etc/pam.d/pop3d, etc.  As far as the specific problem and what 
caused it, that'd require far too much guessing from what you provided, 
but just copying the working service's config file to the broken 
service's config file should be adequate.  If PAM's the problem, that is.

If not, could you have updated the system from one that uses regular 
crypt() to one that uses MD5 passwords, and have a pop daemon that 
doesn't read the new format?  If an old acocunt with the old password 
still works, but a new account with different format passwords doesn't, 
it's possible that the component your pop daemon is using to verify 
passwords can't figure out what to do with the new format password. 
Look at /etc/shadow in a text editor (as root - be careful not to save 
when exiting if you change anything) and see if the password field (the 
second colon-delimited field) is the same length in your login's entry 
as your girlfriend's entry.  If yours is longer, the "new" password 
format is probably the problem - and whatever the pop3 server auths with 
will likely need recompiled to support it.

That should keep you busy for a few minutes, anyway, even if it doesn't 
solve your problem. :)
