I have a distributed environment setup with (mainly) linux machines using nfs
and NIS. The home pages of the several users are distributed by several
machines and accessed by NFS using autofs. All mail is processed by sendmail
in a central mail hub and has a builtin procmail configuration.
For each received mail, procmail must access, by nfs, the $HOME of the
destination user looking for .procmailrc. I noticed that when the home
directories of some users are not available (this happens when a given machine
is down) and there are too many incoming mails, this occasionally makes
sendmail to hang (due to a too high load).
We had a similar problem with the .forward files sometime ago and we bypassed
it by changing the sendmail configuration such that the .forward files are
installed in the local disk of the mail hub. I would like to follow a similar
strategy with procmailrc, but I am not sure if and how it is possible to
change the procmail configuratiom such that it looks for procmailrc in an
alternate directory and not in the $HOME directory.
Any hint/help will be welcome.
Thanks in advance,
