Hello,
a customer of mine has a domain hosted on my server (eg.
specialservice.com). i configured a mailfilter with a forwarding rule
for them, because they want to have a copy of each mail on their own
mailserver (other domain, eg. ourcompany.org). it looks like the
following (eg. for the users email
[EMAIL PROTECTED]):
if ( !/^X-Spam-Flag: YES/:h )
{
cc "[EMAIL PROTECTED]"
}
if a a co-worker sends an email from their own company server, eg. [EMAIL
PROTECTED]
, to the email address [EMAIL PROTECTED], my mail
server makes a carbon copy to the receivers company address, mentioned
in the mailfilter ([EMAIL PROTECTED]). now the
following happens:
Mar 4 09:33:13 ares postfix/smtp[4111]: C2AE58579E: to=<[EMAIL PROTECTED]
>, relay=mail1.ourcompany.org[xxx.xxx.xxx.xxx]:25, delay=6.9,
delays=0.16/0.18/5.5/1, dsn=5.7.1, status=bounced (host
mail1.ourcompany.org[xxx.xxx.xxx.xxx] said: 550 5.7.1 local domain
specified from non-local IP (in reply to end of DATA command))
I think the customers mailserver is a microsoft exchnange server.
because the copied mail has the unchanged FROM Address in it, their
own domain, but a not allowed MTA IP address, the message is not
accepted.
any suggestions what I can do? is this behaviour of the customers own
company mail server compliant to rules? Whitelisting? Or is rewriting
the FROM Header the only choice I have?
many thanks for your help
