I have the same problem or an equal problem. I can add all addresses to an alias account but addresses from the same domain.

For example

myname@mydonain.com  -> to alias  myalias@mydonain.com doesn't work
myname@otherdonain.com  -> to alias  myalias@mydonain.com works

The logfiles seem to look okay and I get an 'success' message too. To which logfile do refer to? Anything else I can do?

Regards
J.

And this is how the admin panel looks like: Screenshot admin panel

This only happens for me with one mailaddress (jens@jens-consulting.net used in this example), it doesn't happen with stan@laurel.net for example.

Any ideas?

TIA J.

Sorry for the delay, here is the log:

I've tried to change

"moderators_in_domain += stripped_members[i.username]"

with

"moderators_in_domain += stripped_moderators[i.username]"

but nothing has changed

Thanks, Mattia

Now that it looks like two different problems, I'm sorry that  I hijacked this topic here. Sorry guys! Should I open a new one?

Yes! It was done manually during a migration.
