Re: [Dovecot] Dovecot crashes with malformed Qpopper's mbox

...

Dovecot dies while processing UIDL command when accessing malformed Qpopper's mbox which has duplicated "From " separator. Qpopper occasionally makes such header while rewriting mbox.

Thanks, fixed: http://hg.dovecot.org/dovecot-1.0/rev/89aa4c7f40b7

It works. Thanks you.

Although the malformed mbox I sent is consists of 2 messages, Dovecot recognizes 3 messages.

 +OK Dovecot ready.
 user xxxxxxxx
 +OK
 pass xxxxxxxx
 +OK Logged in.
 list
 +OK 3 messages:
 1 23
 2 940
 3 968
 .
 retr 1
 +OK 23 octets
 X-UIDL: i[f"!$h*!!S67!!/RW!!
 .

In the above pop3 session, message #1 and #2 is originally one message, so Dovecot should recognize that the whole mbox contains 2 messages, not 3 messages.

I would like you to consider improving Dovecot to skip second (and duplicated, unnecessary) "From" separator.
