Hello!
By now, 2 people suggested to change the Received-Headers as
the are generated by Exim to make them more compliant to RFC822.
They state that writing the IP-number beneath the hostname
violates RFC822, that allows Received-headers in the form:
Received: from alpha.cyberhome.de (root)
by mail.provi.de with esmtp (Exim 1.73 #14)
*or*
Received: from [194.77.164.44] (root)
by mail.provi.de with esmtp (Exim 1.73 #14)
but not both:
Received: from alpha.cyberhome.de [194.77.164.44] (root)
by mail.provi.de with esmtp (Exim 1.73 #14)
As far as I'd like to interpret RFC822, I tend to agree (though
no mailer has rejected our headers so far).
To make the Received-headers easier to understand and change this
behaviour I applied the following change to host.c:
123c123
< sender_fullhost = string_sprintf("(claimed %s) [%s]", sender_helo_name,
---
> sender_fullhost = string_sprintf("(%s) [%s]", sender_helo_name,
130c130
< sender_fullhost = string_sprintf("%s (IP %s)", sender_host_name,
---
> sender_fullhost = string_sprintf("%s [%s]", sender_host_name,
133c133
< sender_fullhost = string_sprintf("%s (claimed %s, is IP %s)", sender_host_name,
---
> sender_fullhost = string_sprintf("%s (%s) [%s]", sender_host_name,
Most important is that square-brackets are not legal as comments in
RFC 822, and just a single system is expected after the "from"-keyword.
Greetings,
Georg
