We have an intranet system creating automatic messages from web pages.
We use the sendmail feature of the intraserver which has a private
IP-address. recently the mail messages have been jammed in the mail
que. There is a status message in the mail que of sendmail:
(Deferred: 450 4.1.8 <apache [at] localhost.localdomain>: Sender a)
The receiving mail box is of course in the public internet. So I
understand that the POP/IMAP server is rejecting the message due to the
unresolvable sender address.
How could I have the sender information be shown acceptably. And why is
it not showing the sender given in the message headers (FROM:)?
We have static IP addresses so DNS entries could maybe used. Being
quite ignorant of network administration issues I would need detailed
instructions.
Thanks for help,
Harri
