9 Okay. I have been using all kinds of software for handling email,
10 dating back to my OS/2 days in the early 1990's. I regard my current
11 set-up as sweet.

18 Certainly.
20 I wanted the messages to be stored in a single, dedicated logical volume
21 in my DASD farm. Dovecot always stored them in each user's ~/Mail/
22 directory, so they were all over the /home L.V. In contrast, dbmail
23 uses a database, in my case PostgreSQL, so it is up to the database
24 administrator to decide where they go; but it is always in the one
25 place. This makes for easy backup and restore: a cron jobs runs
26 pg_dump every night on the dbmail database..

36 The recipe syntax for procmail is seriously ugly. Sieve looks like
37 most other non-procedural languages from the early 1980's, although it
38 arose in the 1990's. Since I am an old geezer who has been programming
39 since the early 1970's, this syntax felt more comfortable. Sieve is
40 also integrated into dbmail.

47 I have never used maildrop.

54 I use a quarantine folder in my IMAP4 account, and my sieve script
55 places spam and infected messages there. Since the physical location
56 is on a logical volume that holds a PostgreSQL tablespace, any malware
57 is not executable, as that L.V. is mounted with "noexec". This is
58 another advantage over placing mail in the /home L.V., in each user's
59 home directory.

66 I don't know about maildrop, but procmail is usually managed centrally
67 and hangs off the tail end of Postfix, Exim, Courier or whatever MTA you
68 have. I always switched to root to maintain my delivery recipes, back
69 when I ran procmail.
