I've seen benchmarks that say just about anything. Even when they're not designed to produce a certain desired outcome, benchmarks are very often biased by factors that aren't always immediately obvious. For one, they tend to reflect the knowledge base of the people configuring the software under test. If Acme Consulting Group compares Postfix and Sendmail and finds Sendmail performs better, what's more likely: That Sendmail beats Postfix, or that Acme's staff simply knows Sendmail better than they know Postfix? High-performance benchmarking can also reveal performance characteristics in the OS or hardware that happen to favor a particular program. And maybe the OS wasn't tuned best for this or that program. When you're talking high-performance, the whole system really does matter. If you're doing the benchmarks are for your own use, then most of these concerns don't matter, because of course it's what you're using and what you know that counts. But taking someone else's benchmarks and generalizing them to other situations can be a very misleading thing to do. This is not to defend Sendmail in this respect. I honestly have no idea. Just...

I've seen benchmarks with postfix spanking sendmail on performance, and exim handing it right to postfix. The guys I've talked to who handle _big_ mail heart exim. Where sendmail really shines is when you need to do something none of the others have thought about yet - sendmail lets you control everything with .cf.

This has been answered, however, I just wanted to add my .02 drachma: Just because something has more flexibility is not necessarilly a reason for choosing it over something less flexible. The majority of vehicles on the road are cars, yet both pickup trucks and tractor/trailers are more flexible. With great flexibility comes great complexity. 99.999% of the flexibility in sendmail is unnecessary for %99.999 of the sites requiring the suse of an MTA. I don't, nor do most people I know, need the ability to gateway between the Internet, ARPANet, or UUCP. Postfix has, as far as I know, a good majority of the flexibility of sendmail at a fraction of the cost in terms of readability and maintainability. Sendmail is still (and probably will be for as long as Eric Allman is alive/maintaining it) the work-horse of the internet. If I need speed and throughput, I'd still choose sendmail. If I need massive scalability, I'll choose sendmail. If I need to deal with wacky and bizarre, I'll probably choose sendmail. If I need simplicity, readability, ease of maintenance, and basic configuration, I'll go with Postfix. I know them both equally as well (which is to say, neither as well as I ought to, both farm more than want to), and in general, I prefer postfix.

Exim is maintained by a group at the University of Cambridge (UK), though I don't know how central the project's structure is regarding the main author. I really do have to say that my favorite all-time mailserver has been qmail. The one thing qmail lacks is many of the more complex and regular features that are common with systems like Postfix, Exim, and Sendmail, as well as integration with heavier-weight IMAP back-ends. There is a large amount of qmail-specific software out there, and I found qmail's code to be wonderful to hack on when I needed to add extra features (such as editing qmail-smtpd to do more stuff at the SMTP-end). I haven't found a mailserver that scales better than qmail either for handling gigantic amounts of email flow. That said, finding others with the breadth of knowledge that I have on qmail proves quite difficult. For our IT clients, we just use Postfix because it is something that "everyone can administer" (hooray pragmatism). At "previous job", I hosted all client mail (for 30k+ domains) through two machines using one as the mail-store (w/ courier-imap) and one as the front-end filter/remailer (for email forward accounts). It was wonderful. -- Coleman Kane ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

If I remember correctly, that "back door" was only available when Sendmail was run in debug mode. I seem to remember this because a friend of mine, Henry "no relation" Hall, was going to join us for dinner at the Hacienda Mexican restaurant on Daniel Webster Highway in Nashua with a bunch of other Digital people. Then I heard on the car radio about this "worm" that was attacking systems. I gleaned enough from the radio broadcast (an oddity in itself) to relay this to Henry, who instead of coming to dinner made sure that the gateway email servers in Digital were running Sendmail with debug mode turned offkeeping Digital from being affected.

Also, I think OpenBSD uses sendmail by default. Postfix & Qmail have been designed from the beginning to be secure. Sendmail has had it added. It's very hard to add after the fact. Multiple layers for security in depth. Run qmail outside the firewall, postfix inside and sendmail/exchange on local boxes. Simplicity: Simpler configuration syntax. Fewer tools needed.

I'd like to also point out another feature of Postfix that some of you might also not be familiar with. Notice the "hash:" above in the "transport_maps = hash:/etc/postfix/transport" line. If you compile Postfix with the -DHAS_MYSQL option, then you can replace this with "mysql:" and the filename after the ":" is the location of a specially-formatted .cf file that tells postfix to connect to a mysql table and where to get the information that it wants. Postfix uses a database-abstraction model for maintaining most of these "mappings" in the system. Pretty much any configuration option that accepts such a parameter can be turned into a MySQL table. This greatly increases your ability to perform dynamic run-time configuration changes at will (without restarting postfix). I believe that PostgreSQL support also exists as well, for those of you who are that way inclined. -- Coleman Kane ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Sendmail may be the ultimate mail server software ever, but you practically need a formal degree in Sendmail to get it to perform many of the complex operations that many other mailservers can do in a seemingly more straight-forward manner. For instance, Shawn O'Shea just pointed out that you can dynamically define new transports for postfix, and then address this problem by setting up a "lameservers" transport that behaves in the 5-rcpts-per-message manner using configuration options that are much more lexically understandable. Maybe sendmail *is* the best option if your primary job is a 24/7 mail relay operator... but I don't want to have to learn a (sort of) brand new language for telling my mailserver what to do. I have got better things to do with my time. I'd take the "less features, but easily configurable" mailserver over the "mailserver that you could write a .mc that would compile the mailserver itself if you wanted it to", because I'd spend less of my time administering my mailserver, and more time on Paying Job (TM), and hobby projects (FreeBSD, etc...). -- Coleman Kane signature.asc Description: This is a digitally signed message part ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
