POP3 Dovecot Login Failure

I get the following error on two user accounts when they're trying to POP3 (Dovecot) login ...

The account receives lots of email (5+ per hour), and until recently was working fine.

Dec 23 22:25:52 ext52 postfix/local[29780]: 107B150502: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0, status=sent (delivered to mailbox)

... with this account having a .forward to the web4_vic account.

... Maildir is unticked. I assume this means that it's mbox?

 

Anyone have any thoughts?
If I change to maildir, would it fix the problem?

 

No ... only 2 accounts and both give the POP3 login failure

 

Please enable Maildir, and then send an email to both accounts first before you try to fetch emails. Maildir will be created when the first email arrives.

 

I activated MailDir, but still no joy ...
