Hi,
After completely abandoning the use of a Plesk based Linux package (see
previous discussions
<https://www.mail-archive.com/mailman-users@python.org/msg63856.html> ), I
have been able to successfully deploy Mailman lists on a
Webmin/Postfix/Dovecot Linux package.
All mailman lists functions & features work well on the later system except
in one specific case. When I try to subscribe to a list (say Mailman)
using an e-mail address based on a virtual domain (say domain.net) which
is co-hosted with the default virtual domain used for Mailman lists (say
domain.org), I immediately get an Undelivered Mail Returned to Sender
error as depicted below :

The 1st mail was sent to confirm the subscription to a list. The second mail
is the response received in return, indicating that the mailman specified
address was unknown. The attached error report follow thereafter.
The collocated virtual domains labeled domain.org and domain.net are
hosted on the same physical server vps12345 at ovh.net, sharing a common IP
address.
Would such behavior be related to a bad or incomplete definition of the
mydestination / myorigin parameters in the Postfix main.cf file ?
Here is an excerpt of the related values produced by the postconf n
command line :
----------------------------------------------------------------------
[
]
mydestination = localhost.$mydomain, localhost, localhost.localdomain
mydomain = localdomain
myhostname = vps12345.ovh.net
mynetworks = 127.0.0.0/8
myorigin = $mydomain
[
]
unknown_local_recipient_reject_code = 550

------------------------------------------------------------------------
If not, what else could cause such failure ?
Thanks for any feedback / help on this issue
