- Here's an update on our ugly little problem with our X.400/Internet
- gateway here at MasterCard. To refresh your memory, we bought
- Soft-Switch's group of products (Soft-Switch X.400, Soft-Switch
- Central, Soft-Switch MHS, etc.) to connect all of our e-mail systems
- together and to connect the whole assembly to AT&T Mail via X.400.
- (I'm sending this message from QuickMail.)
-
- After months of whining on our part, Soft-Switch finally put the
- appropriate expert on the job, and this morning he started asking
- specific questions about what was in our logs and what showed up in
- the "names directory," and now he's got a few of us convinced that the
- problem lies in the way AT&T Mail does SMTP to X.400 translation.
-
- When I send a message out, Soft-Switch X.400 sends my X.400 address as
- c=us, admd=attmail, prmd=MasterCard, ou1=0205295, sn=Hicks, gn=Brad.
- (Which is correct.) When AT&T Mail translates this to SMTP, they send
- it as follows: mc/gn=Brad/sn=Hicks/ou1=0205295@mhs.attmail.com. Note
- carefully that "mc" instead of "prmd=MasterCard"; that seems to be
- where the problem comes in.
-
- When a ListServ turns that around, AT&T retranslates it back into
- c=us, admd=attmail, ou1=0205295, sn=hicks, gn=brad, dda=id!internet
- (b)mhs(b)mc. Notice that not only is the DDA field filled in (the
- problem we'd noticed, which it turns out Soft-Switch can handle) but
- the PRMD field is missing!
-
- In other words, AT&T translates X.400 addresses to a non-standard form
- that even they don't or can't parse correctly on the way back in.
-
- At the very least, the problem does not lie entirely with Soft-Switch,
- and since I probably gave that impression in the past, I would like to
- apologize and clarify things.
-
- *sigh* When we call AT&T Mail tech support, we get people who haven't
- the foggiest idea of what SMTP or X.400 mean, let alone the niceties
- of addressing or the concept of ListServ. I know that there are X.400
- and SMTP wizards who work there, but we don't know the magic words to
- get the people who answer the phones to let us talk to one. Can any
- of the AT&T people who read this help us out?
