Because it has too many features (is complex), between aliases, .forward
files, procmail, ... it gives both the user and the administrator "too
much rope". Sendmail compatibility also imposes fragile loop detection
logic, less efficient single-recipient per-envelope processing. When
aliases expand to multiple recipients, and one soft-fails mail
delivery to the others can happen multiple times...
These days, users are far better off with delivery to an IMAP store that
is not tied directly to any login account they may or may not have.
Perhaps they authenticate to Dovecot via PAM, but the mail store should
own the mailbox, not the user.
