- I have recently abandoned UCX 2.0 SMTP mail in favour of MX for a couple of
- reasons (detailed below). What sort of training, etc have you done? If you're
- worried about having to use SMTP% instead of MX% for specifying the protocol,
- VMS mail allows any transport to use any prefix by defining a (system) logical
- like:
-
- $ DEFINE/SYSTEM MAIL$PROTOCOL_xxx <transport_image_filename>
-
- Basically, you can make MX% use the UCX SMTP transport, or vice-versa.

- The sending and receiving of SMTP mail are quite different things. It is not
- really possible for the UCX SMTP server to pass things on to MX (since it
- doesn't know anything about it) - the SMTP server calls the mail callable
- interface directly to deliver the message to the user.

- I suspect you have to use the original install kit to get the correct version
- of the NETLIB support. When you install MX, it links a lot of the programs
- against a shareable image which provides the TCP/IP mechanisms.

- I can't think of a way to make this work (but you could be right :-).
-
- The reason I switched from UCX SMTP to MX is simply that MX is quite a
- bit richer than UCX. In fact, I read somewhere in the UCX doco that the
- SMTP mail implementation is a fairly "minimal" implementation - it handles
- sending and receiving SMTP mail, but is not very sophisticated when it
- comes to routing, etc.
-
- MX allows me to do a few key things which I couldn't find a way to do
- with UCX.
-
- The first was the ability to define routing paths. This allowed me to
- define some "intelligent" routing paths, so that local mail got delivered
- locally, while other mail goes out through our corporate mail server. It
- also let me set up mail so that our domain name is the mailing address -
- i.e. my e-mail address is wewila@itwol.bhp.com.au instead of
- wewila@<machine>.itwol.bhp.com.au on each machine where I have an
- account. With MX, it was as simple as defining the path "iwtol.bhp.com.au"
- as "Local". I couldn't find a way to do it with UCX (has anyone else?).
-
- The other nice feature of MX is address rewriting. This lets me use the
- MX machine as a gateway to other machines which don't have direct SMTP
- mail capability. Even without using "SMTP over DECnet" (a feature
- provided by MX, but not UCX), I can get mail delivered to DECnet nodes
- by address rewriting.
-
- In general, MX is more complete than UCX SMTP, easier to configure,
- more flexible, and much better documented.
