The best way to diagnose procmail errors is to have it logging in verbose
mode. You've almost got that configured:
SENDMAIL=/usr/sbin/sendmail
LOGFILE=$HOME=/.maillog
VERBOSE=yes
Except for the typo in your assignment to LOGFILE.
I think you mean:
LOGFILE=$HOME/.maillog
Fix that, and you should see copious information in $HOME/.maillog to help
you diagnose procmail problems.
SUBJECT=`formail -zxSubject:`
:0 h c
* ^TO(_dot_)*unsubscribe(_at_)domain(_dot_)com
{
:0 h c
| mkdir $SUBJECT
}
I see a few problems here:
(1) The 'h' flag means 'Feed the header to the pipe, file or mail
destination'. This has no meaning when used on a nested block
(a {...} construct), since you're not piping the message to anything.
(2) You've got the 'c' flag twice. You should probably pay close attention
to the following section of the procmailrc man page:
c Generate a carbon copy of this mail. This only makes
sense on delivering recipes. The only non-delivering
recipe this flag has an effect on is on a nesting
block, in order to generate a carbon copy this will
clone the running procmail process (lockfiles will
not be inherited), whereby the clone will proceed as
usual and the parent will jump across the block.
If you really want a copy of the message to be filtered by later
recipes (or delivered to your default mailbox), remove the 'c'
flag from the beginning of the nested block.
(3) Since 'mkdir' isn't actually doing anything with the message contents,
there's a good chance that it will exit before procmail finishes
writing the message header to its stdin. This will generate an error.
Take another look at the procmailrc man page, this time at the
documentation for the 'i' flag:
i Ignore any write errors on this recipe (i.e., usually
due to an early closed pipe).
Hope this helps,
