Hey Johnny, I recently installed DECmail-11 on RSTS
the other evening,
and I'm noticing some undesirable behavior with the mim.stupi.net
<http://mim.stupi.net> email gateway going out from inside HECnet.
Firstly, it's worth mentioning that gmail won't accept a recipient
address with colons in it, unless you put double quotes around it.
For example:
MARDUK::PHIBER@mim.stupi.net <mailto:MARDUK%3A%3APHIBER@mim.stupi.net>
...won't be accepted as a recipient, and the message is immediately
red-flagged in gmail.
Well, that's gmail for you. Have nothing to do with Mim.
However, if you do the following:
"MARDUK::PHIBER"@mim.stupi.net <http://mim.stupi.net>
...gmail accepts and delivers it, MIM relays it correctly, and I receive
the email in RSTS. Nice.
Yes. That is nice. :-)
Unfortunately, the reverse is failing. If I respond or
send mail out
from DECmail, mim.stupi.net <http://mim.stupi.net>'s sender address
rules reject the message:
This is Postmaster <MIM::POSTMASTER> at MIM::.
I'm sorry, but I could not deliver your mail.
An error occured while trying to send it, and I cannot recover.
Orignal recipient was "PHIBER(a)PHIBER.COM <mailto:PHIBER@PHIBER.COM>"
Actual error is: Fatal address error.
Additional information:
5.1.7 The sender address <MARDUK::PHIBER@mim.stupi.net
<mailto:MARDUK%3A%3APHIBER@mim.stupi.net>> is not a valid
5.1.7 RFC-5321 address.

Please let us know if you can correct the sender address restrictions on
mim. I tried with quotes, but that didn't help either. :)
Well, that is gmail for you again. The really annoying thing is that
according to RFC 5321, a receiving mail server should *not* try to
understand the local part of a mail from header. Especially not if it is
within quotes. To do so is actually violating RFC 5321.
And gmail is doing exactly that, and then giving an error claiming that
the mail is not conforming to RFC 5321.
So there you have it. gmail is violating RFC 5321, and giving an error
that it is the other side that is violating that RFC.
Not much I can do about it. Just about any other mail server will accept
your mails just fine. It's only gmail that have this error/problem.
And Mim is already putting in quotes around the from address for you in
this situation.
