Let's see if we can go further.

Exactly. I really don't understand this. Ben Parker (who I've always 
found to be *very helpful*) has verified that we are running the same 
build of listserv 14.3. Our system has a slightly later version of 
Solaris (5.9 vs 5.8) but I can't imagine that this makes a difference.

The precipitating event in your case was a user who tried to replace an 
existing password. When LISTSERV sent the confirmation request, the 
user's email system responded "user unknown." LISTSERV then notified you 
with a message with "Undelivered mail" in the subject line.

I did something that I expected to produce exactly the same results, but 
in my case the user was creating a new LISTSERV password. LISTSERV sent 
the confirmation request and the user's email system responded "user 
unknown." LISTSERV then notified me with a message with "Delivery error 
report from" in the subject line. The MIME boundaries in this message 
were correct.

I think the key issue is this (from your message that arrived while I 
was composing mine):

I could repeat your test more exactly, but it would be a bit of work to 
create a working password and then have the address go bad so that the 
replace failed. It would be easier for you to repeat my test - try to 
register a password for someone with a non-working email address.

Under these circumstances, I would be tempted to upgrade to 14.4. This 
seems like it is due to some minor glitch in the code which appears 
under very specific circumstances. Even if this does not fix the 
problem, you will probably get a much better response from L-Soft if you 
are demonstrating problems with their current release.
