Auto-Reply stopped working

Update: just tested by sending mail from an external account and the auto-reply was sent.
Looks like the auto-reply isnt sent only when the recipient’s account is on the same server.

Hello, after the last upgrade from webmin 1.585-1 to 1.590-1,
which ended up leaving two versions of webmin installed (see,
now the auto-reply feature isn’t working.

I checked

/etc/aliases -> entries are there
/var/virtualmin-autoreply/ -> files are there
/var/log/maillog -> it says delivered to command: /etc/webmin/virtual-server/ (args ommited)

Tried enabling “Allow mailbox users to create mail filters” under Email Messages > Spam and Virus Scanning deleting and re-creating the auto-reply message, but it didnt work.

Any ideas?

Thanks in advance
