How to make Sendmail forward all incoming mail to localhost port 26 (Domino mail)
 

Here is my problem, I have sendmail configured with antispam software, etc on my server. I also have Lotus Domino for groupware/mail/etc. on the same machine, with the lotus smtp task listening on port 26 (since sendmail has 25).

How do I configure sendmail to deliver all incoming mail to localhost:26?

I have found a couple of howtos on the net but they all describe how to forward to another host and another port, and I just want to forward to another port, on the same host (localhost).

When I tried to do what they recommended I got the error "Mx problem, mail loops back....."

just configure the lotus thing to listen on 25 .

What is wrong with that?
(of course shutoff sendmail)

whell, I want sendmail to act as incoming relay since I have configured MailScanner, Spamassassin with sendmail. I don´t rely on lotus antispam / antirelay protection, so there is why I want sendmail to take care of everything first.

appearantly didn't understand the question
 

speedgelb asked about feeding incoming mail through sendmail in order to apply spam and/or virus scanning to that mail then pass it along to Domino.

There are, perhaps, ways to get Domino to pass mail through clamav, spamassassin, amavis, etc. but I haven't found any. I also do not know of any reasonably priced spam/virus tools for Domino. I used a tool many, many years ago but it altered all email and it appeared to be from the virus scanner - NOT an option.


IMHO

The most important steps in solving problems are to:
1) determine and ask the right question
2) answer the question that is asked

If the stated requirements are not met, a response is not a solution.

If further details are need for the problem, ask.

ALWAYS try to be respectful. One never knows the level of expertise of the person asking.

My intent is NOT to scold but to help responses be more precise and help so please pardon me if I have given any impression to the otherwise.
