Issue Having 87k mails in inbox

[sCHween]

Hi there

as it seems a customer shared his password with the wrong people. Now we have a lot of outgoing mails - which I was able to remove by clearing the queue. But a few 10000 were already out and now most of them were rejected. How can i remove all messages came in the last 24h for the inbox?

Thanks for the fish

You can delete the messages from the account. Here are the directory locations

New messages:

/var/qmail/mailnames/example.com/mailname/Maildir/new/

Current Messages:

/var/qmail/mailnames/example.com/info/Maildir/cur/

solved this issue like this.
Get size and number of messages:

doveadm -f table mailbox status -u user@domain.li "messages vsize" inbox*

Delete all with subject undelivered

doveadm expunge -u user@domain.li mailbox inbox\* subject Undelivered

now working to get unblocked on some blacklists like google :S

I've never used the doveadm tool before. Thanks for the tip!
