I recently install Domino 6.5.1 on a box running Red Hat 9.x (not sure on the exact version). Domino runs using the account named "notes" and will not run as root. From what I understand, not being a linux expert, in order for a service or app to access ports 1 - 1024 you need to be logged on as root. Well here is the problem, when I try and run Domino smtp on port 25 (this is with sendmail off and no other services using port 25) no mail goes through. When I switch the Domino installation to use a port above 1024 it works fine but then I have issues sending/recieving mail as everyone else is using port 25. I did entertain using port forwarding but would rather not use that as the permanent solution. As a solution I want to configure sendmail (running on port 25) to forward all mail to my domino installation monitoring port port 2000.
Please let me know how to do this or if there is a better solution. Things also to keep in mind,
- I am not sure on sending mail if it matters that I am running on Port 2000, if so then I would also need the domino installation to send its mail through Sendmail, although I think I could figure that out.
- I would like to have it some I did not have to do any maintenance with Sendmail, so when i add a user in Lotus Notes, I don't need to do anything with Sendmail
- Need to make sure Sendmail is not relaying anything, although currently it does not, just a consideration..
Thanks in advance for the help
