Hello, iRedMail people.

I deleted an unused domain and set the mailboxes to be deleted next day.  There was only 1 mailbox and it used to belong to a postmater (I changed postmasters earlier).  Now I get my inbox overfilled with error messages saying:

* Delete old mailboxes (1 in total).
* <<< ERROR >>> Cannot convert timestamp in maildir path (/var/vmail/vmail1/mail.xxxxx.com/p/o/s/postmaster/), skip.

How can I handle this?

Thanks
