Hi guys, I'm running into a problem where I want to upgrade an ancient
sendmail on solaris 5.8 instance to postfix 2.6.6 running on Linux
RHEL 6.6, but I'm running into problems.
The mailhost needs to access email for '@foo.bar.com', do a lookup
against NIS aliases, and if not found, just forward the email to a
Lotus Notes server which does some old Legacy email lists.
This is not really a supported postfix configuration, since they feel
very strongly that email should be rejected, not accepted and then
bounced. Oh well, I can't help their feelings since I need to make
this work.
I can do LDAP lookups against the Lotus Notes server (8.5.3) but for
the life of me I can't figure out how it translates
'john.t...@foo.bar.com' into the info it does have, which is:
# ldapsearch -h hdqmta.foo.bar.com -b "o=BAR_FOO" -x -LLL
'(sn=Test)' cn sn uid givenname mailaddress
dn: CN=John Test,O=BAR_FOO
sn: Test
givenname: John
mailaddress: john.stof...@bar.com
It's really frustrating. I've tried setting up postfix to define the
'fallback_transport' to point to my Notes server, but no luck.
And of course the local NIS alias file is sending email to the new
Exchange server and/or the mailman server. So I've got three seperate
destinations to send email too, but only two of which are fully
defined.
I really don't want to go back down the sendmail route if I can at all
help it. It's just so damn baroque and frustrating to use. Not only
is the language terrible, the darn M4 macro language they use for
human readable configuration is almost as bad! I always feel like I'm
doing cargo cult programming when I hack sendmail, even with the bat
book on my altar and some fresh goat's blood at hand.
Pointers? I've been looking at the postfix.org docs, and such threads
as:
https://sourceforge.net/p/postfixadmin/discussion/676076/thread/2670aa6a/
https://groups.google.com/forum/#!topic/mailing.postfix.users/mhX_exJr2CQ
And there's just no luck.
Thanks,
John
