Ideally it would be great if someone had worked with both programs and could compare how much effort it took to reach the same result. i've worked with both and more programs, as I said before. That should give you a good basis to remember some circumstances where something was very easy to configure in one product and much more difficult in another. That is what I am looking for, the gotchas that you encounter when you start to learn a program.
Sorry but I don't understand much of your words... sorry! My English comprehension is bad sometimes...
Don't worry, many of the posters here don't use English as their first language. I don't either. What I meant is if you know a how-to where some of the problems are described that Qmail beginners will probably experience. For example: When you only define a relay domain in relay_domains in Postfix, no recipient validation is done, since the relay_recipient_maps parameter is empty. Of course, the documentations tells you to set up relay_recipient_maps, but as a beginner you might forget to do so.
release. That is not important. I assure you I have used Postfix and I missed mails, because of smtp deliveries if some cases. However that thing never happened with qmail, independently the type of delivery, domain existance or not, etc. That is also what I am looking for. Can you remember under what circumstances it happened and how long ago (which Postfix version)?
Uf... I'll try to explain as good as possible in my bad English. As smtp local server, I tried to send mails and none of them reached its target; qmail does: it sends any mail I want it does, even with "fake" accounts, with my regular MUA.
Did you find out the reason? Postfix logs everything, so you should be able to find the cause of the problem. The only situation where I definitely lost a mail was, when I severely misconfigured my machine: I send the mail to a nonexisting recipient address. Okay, so Postfix tries to bounce the mail back to the sender address. Unfortunately, I also used a nonexisting sender address. In that case, Postfix sends the undeliverable mail to the 2bounce recipient (postmaster). Well, you might guess it, postmaster wasn't set to a valid address either. (^-^) The result was, that Postfix finally deleted the undeliverable mail out of the queue. So it took some real effort to lose the mail. That was in the very beginning, when I started to learn about Postfix and send a few testmails. At least I could reconstruct what happened in the log.
Grin! If Postfix has (copied) all those features you like I don't need to learn Qmail. (^-^)
Ha, ha, ha... sharp!
Of course, why would I spend so much time just to do things a different way? If I don't gain something I don't have yet, it is not worth the effort.
Uh, which one? The only one I can remember was a TLS problem for Postfix 2.1. At that time Postfix itself had no own TLS implementation, so the support was added with a 3rd party patch. That was also origin of the security bug.
Sorry, I can't remember: my memory is not as good as for remembering every issue with all programs I don't use... But I can recall several holes.
Since I do use Postfix I do monitor the security lists closely, and I can't recall any security exploit for Postfix aside of the mentioned third-party patch.
That is exactly my point. I like to learn new things, but I also like to know what I am about to start, especially when I decide to learn a new MTA. A good start is important. What mailinglist/website would you recommend for a QMail beginner?
First, to install qmail/vpopmail, www.shupp.org/toaster And then, if you like, there are many mailinglist and websites to find for information. But I assure you if you install qmail, you won't need anything, because you will forget you have a MTA installed and working.
Where are good sites with accurate documentations and how-tos? I just saw http://cr.yp.to/qmail.html, which had some nice information, though it seemed a bit old (they were talking about the situation in 2001).
Yes, this is the "strange" Dan Bernstein site: the beginning of all, but shupp.org wil be definitive for you. It's easier than done. Other, www.inter7.com, and much more.
I'll take a look at them. As it happens, I just read a request for help in the German opensuse list. He is looking for a mailing list on Qmail. Can you recommend one for him? For the moment, I refered him to http://www.mail-archive.com/toaster@shupp.org/info.html. He is trying to find out how to add a custom header (x-original-recipient) to each mail. I know how to do this in Postfix, but not with QMail.
I must say pop mail server was the only thing makes me use qmail, because the typical "popper" is definitely bad (in my opinion, anyway). After that, all my servers intallations, after having sendmail and postfix and deleted it them, all customers phoned and saying surprised: "Why mail goes now so faster and so good, have you changed anything?" And I don't lie. Every time I did, people praised the new service. And I can say they have been many times.
I don't use POP3, I am very happy with Cyrus (IMAP). So mail is passed from Postfix to Cyrus. The resource usage by Postfix on the Server is negligible, the deciding factor on resource consumption is always the imap server (in my case Cyrus). -- Sandy List replies only please!
