I'll take a wild guess at this. My suggestion is that you shorten the
name of the mailing list. That is, "Forum for the discussion of PC user
support issues" is pushing the list address, [log in to unmask], off
the line with the "Reply-To:" and "Sender:" field indicators. That,
coupled with the fact that the "From:" line is syntactically incorrect
is what let this slip through the loop check code. Here's what I mean,
in perhaps more detail than you want to hear!
...dissected mail follows...
>Comments: <Parser> E: Mail origin cannot be determined.
>Comments: <Parser> E: Original tag was -> FROM: Pasarela EAN <--> PMDF
> <[log in to unmask]>
>From: Undetermined origin c/o Postmaster <[log in to unmask]>
A left-hand-side of 'mailer' would signal the loop detection code to
refuse the mail, but the parser tossed the From: line since the <-->
garbage was in there. So, it pretends it's from the local postmaster
and sends it...
>Subject: Failed mail
This is not one of the recognized "suspect Subject:" values. So, again
nothing here to stop the mail.
Now for the body of the mail message...
>Sender: Forum for the discussion of PC user support issues
><[log in to unmask]
> ET>
The loop check code can't tell that the Sender: value is the list address
since it's on the next line. To be fair, I looked at the code and it
does seem to concatenate lines if it thinks that a line is a continuation.
But since the "<[log in to unmask]" starts in column 1 it's not a valid
continuation anyway. The "ET>" split onto a 3rd line would not be a
problem though since 'PCSUPT-L' and 'YALEVM' on the line with 'Sender:'
would have been enough to stop the mail.
>Reply-To: Forum for the discussion of PC user support issues
><[log in to unmask]
> TNET>
Same problem aswith the "Sender:" in the mail body.
So, I'd suggest (if just to protect yourself from the bogus mail
software at <tahat.upc.es>), shorten the name of the list. Flame
the [log in to unmask] too, but I'm sure you already thought
of that idea. :)
