Software for e-mail
Last Update 1999-02-28
All this software is for Unix (maybe for some other "OS" too).
A brief
comparison between qmail and sendmail
based on my experiences.
-
sendmail V8:
-
actual version
(1999-02-05)
is
8.9.3
,
available
at
ftp.sendmail.org,
Berkeley,
a source in Germany is:
ftp.cert.dfn.de
-
The previous version
(1997-10-25)
is
sendmail 8.8.8.
See the
release notes
for more details.
- qmail: another MTA
should be more secure,
since it has been designed for security.
sendmail
comes from a friendlier time.
qmail.org
is another site with some support software.
qmail-1.03
has been released.
-
Wietse's Postfix Project
might be an interesting alternative to
sendmail,
because it is supposed to be quite compatible and extremely fast as well as secure.
However, it doesn't have the abilities of sendmail to route
e-mail between different types of mail systems (except for
the built-in SMTP and UUCP).
Moreover, the first security problems have been detected
(a simple Denial-of-Service attack from a local user is possible,
simple DNS spoofing).
- exim Internet Mailer
similar to smail,
but has more features.
- ZMailer
-
Elm:
Electronic Mail for UNIX,
PGP Support,
more information
-
Mutt,
the
FAQ,
and some
more information.
The local copy of the manual
should answer most questions.
The
PGP
version is available in
Bonn
as well as some
patches for Mutt.
My patches for mutt
puts a blank line between status line and index or pager output
(for 0.93),
(
old versions for
0.91
,
0.89
,
0.85
).
- Some MUAs which I haven't tried:
Ratatosk,
Pine,
Exmh 2.0,
XF-Mail
Some of these patches are unofficial and unsupported,
use at your own risk!
- smstart
was written to run sendmail in daemon mode as without root priviledges
(not from
inetd
).
It consists of a fairly small patch against the sendmail source
(currently version 8.8.5) and the
smstart
program itself.
The author is
Jozsef Kadlecsik.
Check yourself
whether this program is suitable for your situation!
- Sendmail Security
by Russell Coker: run
sendmail
without root permissions (and without source code modifications).
POP and IMAP are protocols to retrieve your e-mail from a mailserver.
