Postfix Acceptable Date formats

[Matt Wynne]

I have a weird problem with another server (a client of course) that any messages that come from them get rejected with the follwing message:

Nov 2 10:31:44 uniquedata-2 postfix/pipe[6727]: 195159618F: to=, orig_to=, relay=cyrus, delay=1, status=bounced (data format error. Command output: matwyn: Message contains invalid header )

No indication of what was wrong. However, I also got this message sent to my .Mac account and that came through, after a long delay, with the following additional header:

Received: from (x.x.x.x) by foo.com via smtpid 0449_55485018_4b91_11da_94e9_0002b3ee5659; Wed, 02 Nov 2005 12:11:01 +0100
Date-Warning: Invalid date header replaced by ms45.mac.com; original content: 02-Nov-2005 10:24:23 GMT

According to RFC 2822 Section 3.3, dates can be in either of the 2 formats above (long or short). So why does Apple’s Sun IMS (that always makes me frown by the way!) that runs .Mac mail feel the need to change it.

If that is the reason why our 10.4 box is rejecting it for the same reason, then does anyone know how to get Postfix to accept different date formats. I’ve looked at main and master.cf as well as looking through the docs on pipe and can’t find anything. Heeeelp!

I’m cross posting this on Apple Discussions as well.

Cheers in advance

Thanks Joel – we’re doing that now and what’s even weirder is we’ve discovered, by sending back and forth, that it only happens to replies. If they send a fresh mail to us or vice versa, it’s fine. If they reply to a message we’ve sent them, it bounces. I’m getting them to send over the error message and replies to my .Mac account.

One of our clients just started having this happen to them, (and we have thousands of accounts over 5 years!) so I just don’t sustpect postfix.

We are going through the troubleshooting now, so I will be sure to check back and post in this thread as well.
