Not with the version of smtplib Lukasz has (python 2.3). It writes to
stdout. I sent to Lukasz a version of smtplib that writes debugging
info to stderr.

In the version of Mailman that Lukasz uses, not exactly. It is logged
to a MultiLogger which tries to log to Mailman's error log _and_ to
the stderr of the process. Because the process is running as a daemon,
it does not have a stderr and thus writing to stderr fails, which
falls back (through _logexc_) to ... writing to stderr. Which fails,
but this time the exception (invalid file descriptor) is not caught
and Mailman barfs out with a traceback like (I manually patched the
smptlib on that machine to write to stderr instead of stdout):

Looking at the code, this seems to be fixed in Mailman 2.1.9, and I
would assume probably in some earlier versions, too.
