Hello,

MTA is qmail, and there is no problem with it (qmail is stopped for current user - sticky bit set). Problem is dovecot - and is not possible to stop dovecot (due to clients)

Hello,

is there some way how to disable temporarily account or access to files. I need to backup with tar, but there is problem when tar is reading and some file changed (with --ignore-failed-read it continues but archive is not created and without --ignore-failed-read it fails). Some accounts are huge ;( Need something like qmail sticky bit or world writable directory - qmail is not delivering when one of above conditions hits.

Stop your MTA.

...

Thank you for helping me.

Hello,

that's not good solution ;( some mailboxes have 1 - 3GB. So need another solution

Or it can be feature request: disable access when user homedir is sticky ?

Then copy mailboxes to somewhere else and make backup there.

Well, the "deny passwd file" would be a great solution about now, don't you think?

Hello,

seem to be problem of vpopmail. There is only solution to set sticky bit on whole domain but no for user (maybe it's possible but i don't know how).

If you just disable a user's access, you also need to kill any existing processes the user might have.

Really? I'm pretty sure I've successfully created tars where files have changed during it and without any special options. And if you're using maildir there shouldn't be any mailbox corruption since only metadata files change.

You could anyway lock mailboxes one at a time. With maildir creating dovecot-uidlist.lock file (but that also means creating the .lock safely so that if it exists, wait until it's gone).
