What problem are you trying to solve? If the question is "can Postfix do

I do prefer, no doubt about it, qmail.
Check www.shupp.org, and install in a twinkle the best mail server
(imho, of course).
And after, enjoy with a master piece of software.
What features were the deciding factor for you to choose Qmail? I don't
have any experience with Qmail myself, I chose Postfix because it has a
great support community, a very active development and the documentation
is extensive and accurate. Features like DSN and Policy Server/Milters
also became very important.

Do as you like. It's only my advice.

But after many years testing nearly every mail server, I don't change
qmail for anything in this world. It's simply a master piece of
software. People who knows me also know my opinion about qmail, and I
think this way from 1998-1999, when I tested the first time.

It's great that you like Qmail, but this doesn't give my any information
to compare it to Postfix. 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.

The first (beta) version of Postfix was released 1999, the first stable
release 1.0 appeared 2001, so I guess you didn't test Postfix at that time.

All features you like in a mail server, qmail does have them. So, why
don't you try and if not of your taste, install any other.
I can assure you my qmail is really the same I've got from 2002. And I
sleep peacefully while qmail works. That's not good, I know, but if you
don't want be ever watching a mail server, install qmail and forget
yourself.

I have heard the same being said about Postfix. I still wonder how anyone
can just install a mailserver and then forget about it. I am always
finetuning the configuration to adapt to new spammer tricks. agreed, it
would probably work without finetuning, but the rate of rejected spam
would probably drop a lot.

A big German ISP tested this, they simply stopped finetuning their
configuration and noticed a considerable drop in their rejection rate.

If I had to choose another MTA other than Postfix I would probably switch
to Exim.

Postfix and Exim are two great mail servers, but I still do prefer
qmail, because (and it's only my opinion) is much better in most cases.
qmail version is the same from 1998, and it does not need any more; but
there are many people around helping and making "add-ons", making it
more powerful and never, never, never has a security hole or anything
like these.
However, sendmail or postfix really have holes... or is that not true?

At least for Postfix it is not true. Sendmail had some problems with
security some years ago. In the last years I they tightened their code a
lot. Though I do remember that Sendmail had a remote exploitable bug last
year.

One good hint how secure Postfix is: Borderware has chosen Postfix as the
MTA of their Firewall.

So decide and have a try qmail, and you'll not be disappointed.

So far, this does not yet give me enough encouragement to invest the many
month of work to dig into Qmail as I did with Postfix. Before I change I
have to know if the annoyances in Postfix are worth dealing with the
annoyances of another MTA.
Every piece of software has some drawbacks, the question is rather if I am
willing to live with it or if I can circumvent the annoyance.

Since I know Postfix quite well, so I know how to work around the
annoyances of Postfix, but that is not the case with Qmail (or Exim or
Sendmail).
Recipient validation for example is very important, how and at what stage
of the smtp dialogue is it done in Qmail? I would probably have to spend
quite some hours to find the anwser. Time is expensive, I only have a
limited supply of it. (^-^)
