Mail Rejections (Exim / Mutt)

flangemonkey · 03-15-2017, 12:17 PM

Hi,

When I try to send emails in Mutt they normally work fine, including 'bouncing' emails onto another address - however when the encoding is 7bit, I can neither bounce nor attach to a new email. [Edit - apparently some 7bit emails can be forwarded, this was a red herring: see attached image for a screenshot of encodings]

The failure message (forwarded as attachment) is:

Quote:

From: Mail Delivery System <Mailer-Daemon@yyyyyy.co.uk>
To: me
Subject: Mail delivery failed: returning message to sender

[-- Attachment #1 --]

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

user@xxxxxx.com

[-- Attachment #2 --]
[-- Type: message/delivery-status, Encoding: 7bit, Size: 0.1K --]

Reporting-MTA: dns; yyyyyy.co.uk

Action: failed
Final-Recipient: rfc822;user@xxxxxx.com
Status: 5.0.0

[-- Attachment #3 --]
[-- Type: text/rfc822-headers, Encoding: 7bit, Size: 2.1K --]
<forwarded email headers>

Now, I am a bit confused, as this affects more than 1 receiving server (tested with Yahoo!, my work email and Live.com)

There is another guy on the internets had this problem, but the question was abandoned before anything meaty was discovered: http://serverfault.com/questions/283...ed-by-receiver

The mail server log shows:

Code:

2017-03-15 17:03:55 1coCL5-0005kW-Ql <= me U=myuser P=local S=33269 id=20170315170355.GD4978@yyyyyy.localdomain
2017-03-15 17:03:56 1coCL5-0005kW-Ql ** xxxxxx@hotmail.com R=dnslookup T=remote_smtp: message is too big (transport limit = 1)

2017-03-15 17:03:56 1coCL5-0005kW-Ql Completed

The message isn't too big - the error message apparently means there are long long lines in the email:

https://bugs.debian.org/cgi-bin/bugr...cgi?bug=822463

So, in really simple terms, can someone tell me what looks like the problem is and has anyone seen a bug report for Arch or Exim or Perl that I can CC myself onto, or a patch or similar I can do to make this work

Thanks

exim is an extremely large and complex email + "code activation" system

if there is a problem with your setup it can even allow remote persons on the internet to root your computer by sending specially crafted emails to exim

my answer would be: use something far simpler, something that installs and "just works"

why are you working with intentionally re-bouncing bounced email ? your not making a spam mailer are you ? those are illegal in the USA

Mutt is a CLI client, so if I see an HTML email I feel inclined to see, I bounce it on to another of my addresses, perfectly legally - and I'm not even in the US...

And as far as I can see the Exim package is correctly configured, but if someone would like to see my config, I'm sure I can put it up here. Personally I believe the problem lies somewhere in Perl or Mutt, rather than Exim.
