I'm on 5.9.11 - additional config details down below.
It appears that fetchmail in daemon mode terminates in an uncontrolled
manner when it encounters authentication failure. The reasons I
believe so are
1. No trace whatsoever in the syslog neither of the auth fail nor
of the termination ("normal" fetchmail messages are logged
though, so my syslog.conf should be OK)
2. Next time I restart fetchmail, It says "removing stale
lockfile"
These are the last two lines of my syslog after I provoked an auth
fail by editing fetchmailrc:
------------------------------------------------------------
Apr 26 08:55:04 cbe1080 fetchmail[716]: sleeping at Fri, 26 Apr 2002 08:55:04
+0200 (MET DST)
Apr 26 09:00:04 cbe1080 fetchmail[716]: restarting fetchmail
(/home/etxbwir/.fetchmailrc changed)
------------------------------------------------------------
When operating in non-daemon mode, it works as expected, i. e. the
auth fail event is syslogged:
------------------------------------------------------------
Apr 26 09:48:07 cbe1080 fetchmail[6488]: No mail for etxbwir(_at_)EMD_SE1 at
ESEALNT442.al.sw.ericsson.se <--- password ok here
Apr 26 09:49:40 cbe1080 fetchmail[6492]: Authorization failure on
etxbwir(_at_)EMD_SE1@ESEALNT442.al.sw.ericsson.se <--- password hosed
now
Apr 26 09:49:40 cbe1080 fetchmail[6492]: Query status=3 (AUTHFAIL)
------------------------------------------------------------
When preparing the config details found below, I noticed that the
behavior is different when invoking fetchmail with `-v -v'. Then,
things *do* get syslogged, and the daemon keeps on running. I suppose
this is the intended behavior? It could be questioned though if it is
meaningful to go on after an authentication failure - I guess it's
normally not a transient error. In our site it will cause account
blocking after three failed attempts.
Related to this, I'd like to add an item to the feature wish-list: add
an option that makes fetchmail send a warning mail upon auth fail
(well really upon any possible reason that causes its termination),
much the way it used to be in the umm, 4.6.x (?) days. In previous
posts on this topic I've been recommended to monitor the syslog, but
no matter how you put it: you end up with yet another daemon that
watches the fetchmail daemon (possibly via syslog). And how about the
health of *that* daemon?
Here are my config details:

Starting fetchmail with -v -v yields the following syslog:

Like I said, in this case, things seem to work as intended - but not
when invoked without the `-v -v'.
