Here we go (no time to SGMLify it sorry):
Q: I want to configure my sendmail to emit only user@domain.name but it keeps
bombing with a "MX points back to myself" error. What can I do ?
A: To send and receive mail with only the domain part of an address, you'll
need to do this:
- use
MASQUERADE_AS(domain.name)
in the whatever.mc file you've written in order to change all outgoing
mail messages,
- make the MX record for the domain point to the mail server
domain.name. IN MX 10 mailhost.domain.name.
- insert the following in the whatever.mc file
FEATURE(use_cw_file)
Using this feature is easier than just put domain.name in Cw because
you'll not need to re-m4 the file each time you add a new domain.
- create a file named by defult /etc/sendmail.cw and add the following:
domain.name
in it. "domain.name" is now a "local" address.
