    First : fetchmail is great - thanks  :)

    I sent this to fetchmail-friends a while back and it was suggested that I send it to the devlist.
    I joined and lurked - and finally got round to sending this in...

    It's been working for years with these occasional hangs that have been
    fixed by popping the bad messages and manually filing them. I finally
    had a bad message arrive when I was in a position to debug!

    Summary : fetchmail hangs during pop3 pull after a mail with a null char.

    The mail with a null char is pulled OK but then rejected by local
    Cyrus lmtp and bounced to postmaster via exim4.20
    The next pop3 pull then fails.
    I've made an effort to trace and I think the hang occurs due to a
    double call to SMTP_ok which is empty the second time. I am pretty
    sure the second call originates at sink.c line 1433.

    in the config expunge 1 fixes the problem (which makes sense)

    general config is pop3->lmtp->local Cyrus IMAP

    So I went through the FAQ G3 points:
    1. OS: Linux RedHat 7.3 kernel 2.6.6
    2. gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110)
    3. below
    4. forwarding to lmtp listener on cyrus 2.2.3 (bounce goes to SMTP
    exim 4.2)
    5. -v -v -f /etc/fetchmailrc
    6. at the end

    nb: SMTP_ok loop start comments are my trace.
