A very good day to you, you and you.

I would like to periodically read and empty users email spools in /var/spool/mail.

Postfix is the one doing the writing, as could be expected.

My thoughts are though, what happens if my shiney script truncates(and writes) to the spool at the same instance postfix wants to write new mail to that file.

Will the world end as we know it ? I just don't know, and i'm worried.

Therefore, my guess is to implement some sort of flock, hmmm, but which type exactly ? What kind of lock does postfix use (if any) ?

I'll bet there is a splendid module availible on cpan that i don't yet know of, i'm hopeful.

Thanks guys, it seems to be the case that this is indeed a postfix thang. Now reading some postfix docs. on this topic.
