I can agree with this. Sometimes though a suggestion starts off as a
complaint.

Just referring to his previous comment; which seem to come from a very
elitist point of view.

But wouldn't it be far easier to contribute if you have it setup and
running? And, if you are having trouble getting it setup and running, then
get told to go read something that you've already read, complain, and get
told stop bitching and contribute, well, seems like it is catch-22. To me,
you contribute once it's working for you; adding to the help that was
given to you- contributing and returning the help done for yourself.

Once I get the thing going I most likely will :)

My mistake, I should have worded it more towards "the majority of replies
to such questions".

I do in fact follow them this way, and the wealth of knowledge here is
astounding. However, the full scope of "help" seems to only begin with
advanced questions. The basic questions get passed over quite often, again
with the majority seeming to be sarcastic.

I don't consider it a tip. I was thinking more along the lines of:

"When configuring Postfix for MySQL, use the virtual maps in the manpage,
replacing each with the proper MySQL syntax, as shown in this example"

That one line would have saved me a lot of pain and frustration. If by
chance I missed it, I would be happy to know where.

Yeah, it may be line noise, but to me all that I read was more specific in
saying "this line does this". Maybe I am having more of a difficult time
because I am used to sendmail?

This is also what makes it more confusing, since there are really no
references to these setups in the postfix docs.

I can understand this now, as I said above a simple line stating this fact
would relieve quite a bit of confusion.

But as I also said, maybe I missed it. I have been through a jumble of
texts trying to figure out where to start and trying to grasp the basic
layout of the MySQL tables.

All in all, I think this will be a great solution, and I would love to see
some more specific documentation! I would love even more to get it working
and write my own howto!

I appreciate you taking the time to reply so thoroughly and allow us all
to get a better grasp on things.

Thanks,
