Hello everyone!
My Carbonio server (latest version) is currently accepting emails even when the destination account does not exist. For example, my domain is test123.com, and if I send an email via telnet or using a tool like swaks, Carbonio accepts both the "from" and "to" addresses even if they are invalid, such as xxxx@test123.com. This happens even though, in the Carbonio web interface under the MTA settings, both "Reject unlisted recipients" and "Reject unlisted senders" are enabled.
Any ideas on what might be going wrong?
Regards,
I found the problem, it was because I had configured the "zimbraMailCatchAllAddress" options for server migration and had not removed it, so it accepted any sender or origin.
After removing it, this issue worked.
Sorry.. 😀
Regards
