- Plesk Onyx 17.5 for Linux
- firstname.lastname@example.org is set up as forwarding destination mail address in Domains > example.com > Email Addresses > email@example.com;
- firstname.lastname@example.org has reached its mailbox size limit;
- Mailbox for mail address email@example.com was turned off in Domains > example.com > Email Addresses > firstname.lastname@example.org;
- After that mail is not delivered to the email@example.com with the following error in

The same error appears in logs if firstname.lastname@example.org is disabled but its folder remains on the file system at
/var/qmail/mailnames/example.com/destination/and its size reached the mailbox limit set previously in Domains > example.com > Email Addresses > email@example.com:
# du -sh /var/qmail/mailnames/example.com/destination/
The issue is caused by bug with ID #PPPM-10245, which is planned to be fixed in product future updates.
- Log into Plesk
- Switch Mailbox back on for the email firstname.lastname@example.org (or for email@example.com depends on whichever is limited) in Domains > eample.com > Email Addresses.
Note: After re-enabling the mailbox, either free space or increase the mailbox limit
