'Undelivered Mail Returned to Sender' error when using an e-mail from a domain co-hosted with the one used for Mailman lists
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@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
