I try desesperatly to send mail to an external domain (actual production domain).
Before some modifications (which one of the long list ?), it worked properly, but i don't understand why NOW it rejects the recipient address (franck.modola@botanic.com) while it accepts the other (fmodola@botanic.com).
The two recipients exist on the production server, and I've configured the MTA to relay to the server IP 192.168.101.31 on port 25.
I've tried from two Zimbra accounts with no change ...
