[Bug 7209] New: Messages bounce when sent to mailing list from Apple Mail through spamc

https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7209

            Bug ID: 7209
           Summary: Messages bounce when sent to mailing list from Apple
                    Mail through spamc
           Product: Spamassassin
           Version: 3.4 SVN branch
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: spamc/spamd
          Assignee: dev@spamassassin.apache.org
          Reporter: jordan@t16.net

When sending mail from an Apple Mail client to a mailing list at the same
domain, all messages would bounce with the following error:

Jun  8 19:14:06 localhost postfix/pipe[6719]: 9C991C45D6F:
to=<jo...@example.com>, orig_to=<st...@example.com>, relay=spamassassin,
delay=1.6, delays=0.94/0/0/0.69, dsn=5.3.5, status=bounced (local configuration
error. Command output: Exceeded max number of arguments (24) in
/etc/spamassassin/spamc.conf )

This could not be reproduced on other mail clients (Roundcube was able to send
to mailing lists without it bouncing).

It could, however, be reliably reproduced on Apple Mail, and it failed
regardless of the mailing list size (not only on mailing lists >=24 recipients
- it also failed on a mailing list with only 14 recipients).

I resolved it for *me* by recompiling spamc with COMBO_ARGV_SIZE set higher. It
looks like COMBO_ARGV_SIZE is supposed to eventually be a config file variable,
but isn't currently, which made this problem relatively difficult to figure
out/solve.

Please let me know if any additional information is required to look into this
further. I was not able to determine what the difference was between sending
from Apple Mail vs. other clients (I examined both strace and tcpdump and found
nothing of value.)

This sounds like either a bug with the glue or a configuration issue with the
glue where it's adding command line parameters to spamc based on something in
the email.  

How does your postfix glue into spamc?

are you able to document the spamc command line run?  Even with something like
ps -auxwwwww running a bunch of times while you send the email?  Looks like
you'll have a 1.6 second window to catch the command line.

Regards,
KAM

This is a user@ mailing list issue not a bug

On the face of it, it sounds like you're trying to give spamc a recipient list.
It should probably be getting a default user in the case of multiple recipients
otherwise it just uses the user data for the first one.
