1The FreeBSD version (1.3.2.6 1999/09/05) has over the NetBSD version
2(1.16 1998/12/19):
3 -l flag (list database)
4 trailing \n on some syslog messages
5 strerror(errno) instead of the %m macro in syslog messages
6 isdelim() used in nsearch()
7
8The OpenBSD version (1.12 1999/06/03) has over the NetBSD version:

12 $SUBJECT substitution in the message
13
14The old debian version has over the FreeBSD version:

16
17The sendmail version (8.68.4.3 2000/04/27) has over the NetBSD version:
18 -fmstxz
19 annoying license
20
21Features in the sourceforge version:
22 $FROM substituion
23 has -j
24 does stupid things with the envelope sender in readheaders(), mistaking
25  it for a bang path
26 wastes time passing the -F argument to sendmail
27 interval is set with -t, but can only be specified in weeks
28 installation procedure
29
30 The -r flag of the sourceforge version is a very, very dangerous thing
31 because automatically generated replies MUST go to the envelope sender.
32 This version also ignores the From header.
