I generate bcc backups with the pattern
backups+DATE.user.domain.tld@myBackupDomain.tld
(for example, backups+20170908.kremels.kreme.com@myBackupDomain.tld)
This puts mail in …/.20170908.kremels.kreme.com/new
What I would like to do is get the expansion to generate the following path
…/.20170908/.kremels.kreme.com/new
Of course the date changes everyday, but it will always be numeric if that helps.
dovecot get the mail from postfix:
dovecot unix - n n - - pipe flags=DRhu user=vpopmail:vchkpw argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${user}@${nexthop} -m ${extension} -a ${original_recipient}
Would it make more sense (or is it even possible) to split the extension in postfix or to do something with sieve? Or is there a character I can use in the extension that tells dovecot to create a path?
Even though I am using a maildir structure for the backups, this "account" never accesses the mail via a MUA, only via the command line when an admin has to restore an email, so it would be much easier to deal with this with daily subfolders.
Or, maybe I make the admins use an MUA? If so, I should replace most of these .'s with dashes…
