mail-crypt and mbox format

[cincodemayo_67 at yahoo.com]

 Thank you for confirming. That was the conclusion I came to, particularly after seeing the structure of Maildir mailboxes and how the individual messages were encrypted. Clearly it would be difficult to do the same with an unlimited number of messages stored in a single file. 

A followup question if I may. I probably should just start another thread, but, how difficult is it to convert to Maildir? Any gotchas? Any differences in how to manage the server? How effective is the mb2md? Not looking for a cookbook, just an opinion on whether it is worth converting. 
We've used mbox format going back before CentOS 5, so change is hard.
Environment is CentOS 7, Dovecot, Sendmail, Pigeonhole, MailScanner, Mailwatch SQL, Thunderbird clients. 

Thanks,Doug

    Hi,   
   My Dovecot server of many years has been set up to use mbox email folders. I want to implement mail-crypt and after banging my head against a wall for a few days trying to get mail-crypt to work I decided to try it against a test instance of my server that I reset to use Maildir format and mail-crypt worked instantly.   
   Does mail-crypt work with mbox format mail folders, or am I wasting my time unless I switch over to Maildir?  The documentation at https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ doesn't explicitly say Maildir is required.   
   Thanks in advance,   
   Doug 
   
   
   
   
   
   
  Mail crypt will not work with it. Mbox format has limited support of features.   ---
