Does anyone know of any other MTAs that can pass SMTP AUTH info along to Cyrus, other than Sendmail? I'm thinking in the base case here, of a single server, for an intranet. We've already, unfortunately, ruled out Postfix earlier last week, I think I remember reading.
Exim, as of version 4.14 for sure, can do this. I am using it this way, with Exim speaking LMTP over a TCP/IP port to Cyrus lmtpd.
Any ideas, pointers to docs for things like this, anyone else done this somewhere, sometime? :(
I do not have shared folders set up here, but I don't see any reason why that would matter. If you decide to seriously consider Exim, email me off-list and I'll forward you the relevant parts of my configuration file.
