Right! I now have the absolute and final answer on this.

This  morning  I've  had a very enlightening private conversation with
John   Sullivan  (thank  you  John)  on  this  topic  which  makes  it
*perfectly* clear that we are suffering from the effects of what could
be said to be a bug in TB!

It  is  now  clear  that TB sends the "Reply-To" name in the SMTP FROM
address  when  talking  to  SMTP relay servers. I can see the sense in
this.  Any rejection notices are routed to the SMTP FROM: address and,
if  you  have specified a Reply-To:, then perhaps you really do wanted
bounce  messages  to go there instead of to the address in the message
x-header  From:  field.  But,  it  is the SMTP FROM (as opposed to the
"From:"  field)  which  is  used by the list server to verify that the
sender is a member.

So, anyone posting to this list with a "Reply-To" *other* than that of
their  subscribed  name will have their posting rejected. What's more,
the  SMTP  FROM  address is used to route rejection notifications. The
above   message   occurs   when   the   Reply-To  address  is  set  to
[EMAIL PROTECTED]  (or  TBBETA).

I  know that, observing list traffic, it looks like we're all set that
way  and  it  makes some kind of sense to change your configuration to
match  (see  Angel,  there  was  a  logic to it ;-]) in reality *that*
Reply-To  has  been  inserted  by the ListServer and *must not* be set
that way at the originating client.

Whenever  *anyone*  posts to the list with this configuration, then we
*all* get the error message (the bounce is redirected to the SMTP FROM
which,  in this case is [EMAIL PROTECTED] and so it goes to the
whole list - aaargh). What's more, we can't see who is the culprit.

1)  I  would  like  everyone  on the list to check that their Reply-To
address  is  the  same  as  their  From: address for posting to the TB
lists.  Check  it  a)  in the address book templates, b) in the folder
templates  and  c)  in  any  QuickTemplates  used.  If it's not right,
correct  it.  If anyone is using TBUDL as their personal Reply-To then
let  me know privately that you were set this way. I know at least one
person *has* to be, because bounce the messages have been coming.

2)  I  will  repeat  this  as  a bug report to both RITLabs (who could
possibly  make it an option as to which of the From/Reply-To addresses
to  use  in  the  SMTP  FROM  protocol  line) and to the makers of the
ListServer regarding a greater latitude on which addresses are used to
validate list membership.

...unless  someone has something more definitive to contribute on this
topic before I go making bold statements to authors... :-)

Cheers,
Marck
