- Mailbox firstname.lastname@example.org is not listed at Home > Domains > example.com > Email Addresses
- The output of the command below is similar to the following:
# ls -la /var/qmail/mailnames/example.com/jdoe
ls: cannot access /var/qmail/mailnames/example.com/jdoe: No such file or directory
Mailbox email@example.com does not exist on the server.
Another solution is to modify contact form to use another existing mailbox.
