[courier-users] Huge "To:" list results in empty message in (old) Courier
Greg Earle
On extremely rare occasions, I get e-mails that are empty, as received on my end via this Courier server. As I receive it, it only has
Return-Path:
Delivered-To:
Received:
Received:
Received:
From:
and that's it. No other headers, no message body.
I asked someone else who received the same message but on a different (non-Courier) server to forward me the raw message, and he got it in its entirety.
When I examined his copy, the "To:"/"Cc:" lines are both one line long, but with a huge amount of recipients. Not many in the "Cc:" field - only 6 - but the "To:" field is huge - I'm guessing well over 100 people, maybe even 200.
It's telling that in the empty message I received, the "To:" header is missing as is "CC:" and everything that follows.
Clearly this is giving Courier heartburn - is there any knob to twiddle to let these messages through?

There are no knobs to tweak. Courier itself does not care what's in the
headers of incoming mail. The only time Courier modifies or does anything
with headers is on messages originating locally, by submitting them to the
sendmail wrapper. Its only treatment on all other mail is to prepend its own
Received: header.
Perhaps you have some custom local mail delivery script that's barfing.

I believe all procmails are similarly old.
Check the man pages for "LINEBUF". The default is 2048 I think, and
you probably need to increase it. You also probably need to look at
what the procmail recipes are doing.
There's a procmail list with some good people on it. And me, but what
are you going to do?
