# We may have a fallback MDA available in case the socket open to the
# local SMTP listener fails. Best to use procmail for this, as we know
# it won't try delivering through local SMTP and cause a mail loop.
# Sendmail without the -t option to use the message headers will work too,
# not just for sendmail itself but for workalikes like exim.
#
# Note1: A disadvantage of using procmail is that local alias expansion
# according to /etc/aliases won't get done if we fall back. This doesn't
# matter in single-drop mode.
#
# Note2: it would be a very bad idea to use any MDA that doesn't return
# a refuse-to-deliver status on disk- or process-table-full
# conditions; mail could get lost that way. Sendmail and all of the MDAs
# like exim that might be lurking under a sendmail alias) do the right
# thing in this circumstance. Matthias Andree warns that procmail does
# not.
#
# Note3: Defalt value of fallback is now off. Matthias writes:
#
# 1. there is no way to predict when the fallback is used. With some MTAs
# (such as those limiting load average), outer circumstances can cause
# the fallback to kick in.
#
# 2. the fallback changes fetchmail behaviour in unpredictable ways. It's
# not only about alias expansion, .forwards to special filters won't
# work, mail may end up in a different place (users claim "mail loss"
# for that).
#
# 3. The claim procmail did the right thing with its exit codes is plain
# wrong. I've seen procmail exit with code 1 when it should have exited
# with code 75, like, configuration errors. Procmail is a dangerous
# beast and is best replaced by maildrop.
#
# 4. if multiple choices exist (like procmail and maildrop), fetchmail
# cannot tell which one it should choose. Say, your MTA is configured
# to use maildrop to deliver to user's mailboxes, if fetchmail then
# chooses procmail, this is plain wrong.

# * Build correctly under Heimdal kerberos if it is compiled with db2 and

# * Build the kerberos.c stuff (KPOP) only for kerberosIV, to avoid breakage.
# I don't know if this is 100% correct, but now at least IMAP and POP3
# behave the same way regarding kerberosV.
# * Build without any fuss for both kerberosIV and V at the same time.
# * Move all the kerberos header mess to kerberos.h, and #include that
# in driver.c and kerberos.c.
