Hi all,

I run a mail server on Maildir. Does Dovecot work correctly if I delete the mail files stored in Maildir? Do I need to run the doveadm command?

I want to run a virus scan on Maildir. When a virus is detected, the mail file is deleted without notifying Dovecot. I assumed this was incorrect behavior for Dovecot.

Please help me when someone has time.

Thanks, Masa

Hi, if you just delete mailfiles in maildir dovecot does not update its index at once it "may" it repair later , delete with doveadm is the right way

Maildir is special case in the sense that dovecot assumes that there might be external changes, so indexes are synced when the mailbox is opened the next time.

Thank you to everyone.

First, try to find antivirus software that can remove files with doveadm. I will share it on this list when I find it.

as an alternative. Consider a script that runs the doveadm import and doveadm rebuild commands from the antivirus action log.

Thanks, Masa

this may not work all the time, in special if you very have big mailboxes
