I follow you to the end. However, I found references by Philip Guenther
(Procmail list maintainer) to suggest the following:
:0 w
* ? progname
| do this if exitcode == 0
# save the return code in a testable variable
ret = $?
# Need the 'E' here as ret will contain the return code of
# the action instead of 'progname' if 'progname' succeeded.
:0 E
* ret ?? ^^1^^
| do this if exitcode == 1
:0 E
* ret ?? ^^2^^
| do this if exitcode == 2
:0 E
| otherwise, do this
If we use that strategy, we might be able to experiment with code as
follows:
:0fw
* !^Subject:.*SAtalk
| spamc -u "$LOGNAME"
SCANNED=$?
:0 Efw
* SCANNED ?? ^^0^^
| spamassassin -a
I was wondering why we could not do the following:
:0
* !^Subject:.*Satalk
{
:0fw: spamassassin.lock
* < 256000
| spamc
:0 efw: spamassassin.lock
* < 256000
| spamassassin -a
}
Shouldn't the e mean execute if the previous recipe's condition(s) matched
but there was an error in the action? What do you think?
By the way, the SA FAQ suggests using a lock. I don't know if spamc
benefits from the lock but I use it anyway.
# The lock file ensures that only 1 spamassassin invocation happens
# at 1 time, to keep the load down.
#
:0fw: spamassassin.lock
* < 256000
| spamassassin
