I just upgraded recently from GPL to Pro, and am finding myself in a difficult bind. Virtualmin keeps re-writing my /etc/procmailrc file which is setup to use Maildir storage, instead of Mbox storage.
Unfortunately when it re-writes the file, because I've selected Sendmail as my MTA instead of something like Qmail or Postfix, it defaults the mail file to /var/spool/mail/<user> , which is something I don't want, because I've specifically setup Dovecot to use Maildir only. Mbox is too flaky and problematic, and while I attempted to setup Postfix, I don't see any easy way of converting my already created domains and users on the system into Postfix's configuration.
Is there anyway to either A) import things into Postfix, or B) turn off the procmailrc re-writing part of VM, so I can rest-assured my customers won't be e-mailing me left and right about not receiving e-mail?
