Hi, Recently I am considering to move to another MTA. At one time I was wondering what mail server big ISP are running. I can't decide postfix or qmail. Which one is best MTA for me? -- Byung-Hee

If you're uber-paranoid about security, go with qmail.> Which one is best MTA for me?The only person who's going to be able to answer that question is you.

Hi!> Recently I am considering to move to another MTA. At one time I was > wondering what mail server big ISP are running.

It's the best MTA for me ;-) Maybe your question could be answered in a more helpful way, if you stated - which MTA you are currently using - what you don't like about it, so you want to switch We are an ISP and we run Sendmail. Works great. I don't like qmail, because for me it's architecture is even more arcane than Sendmail's. And it doesn't log all information Sendmail does - which is important for us when tracing "lost" mails. (remote MTA queue ID, for example) I hear lots of good things about postfix, but switch for the sake of switching? I already have enough work ;-) Kind regards, Patrick M.

I and one of our sys-op has accomplished all of the necessary migration work (coding to re-implement our features, testing, and migration itself) within three weeks, so once you have confirmed what your requirement is, it's not very hard to do. I do not want to say simply that you will want postfix, but I would like to explain the reasons why we have did the migration: - Performance. qmail uses about 3 times of file I/O operation for each mail delivery, compared with postfix. For a busy MX server this means that you have to prepare more servers to do the same job. - Features. Most of extension to qmail has to be done by patching. It's true that there is a lot of qmail patches floating around, but you have to carefully maintain a local qmail tree. Postfix has a lot of built-in anti-spam and other features, and it is relatively easy to implement new feature with Python/Twisted through Postfix's interface - no patch needed for postfix itself. - Manageability. Our system administration team used to be very familiar with qmail. However, for large ISP/ICPs, qmail fails to solve the following essential problems that postfix does not have: - Hard to reconstruct mail queue after damage In postfix this can be done with 'postfix check'. - Have to watch its queue situation Once you got the queue stuck with a lot (200,000+) e-mails that can not be delivered temporarily, e.g. due to a backend hardware issue, all e-mails would be delivered very slowly, and incoming e-mail would make the situation worse. We used to have a monitoring script that adds an ipfw rule to block all subsequent incoming mail to work around this issue. With postfix, stuck e-mails are stored in separate queue. - and a lot more... - Maintainability. Extending postfix for your own need is easy, our new anti-spam system is primarily written as a policy/filtering/table lookup daemon with Python/Twisted, making the code much more easy to understand and maintain. It's not easy for someone to be able to pick up the qmail patch due to the coding style and lack of comments. More importantly, postfix is being actively maintained, but qmail is not. I'm not sure about the problem you are having. If you are going to set up a new mail server (cluster) then don't use qmail, it would be a nightmare if your system grows. Postfix is a good choice, and there are some other choices, e.g. sendmail, exim, etc. Cheers, -- Xin LI <delphij@delphij.net> http://www.delphij.net/ FreeBSD - The Power to Serve! -------------- next part -------------- A non-text attachment was scrubbed...

Thank you for your advices, both in the maintainability and security you replied. And I believe Exim is best MTA as well, indeed :-) Sincerely, Byung-Hee
