That is a real problem. You see, I have several addresses, and some of
them, like the sourceforge one, or the ieee one, do not have an smtp
server (and most nor a pop server either, they act as redirectors). To
send with my "from" set to "something at sourceforge" I have to use my own
postfix, or a good or permissive relay. Of course, a permissive one is not
often good, for other reasons.

It has happened to me, often. The problem when using my provider smtp (two
providers, not only tiscali) is that many times I never know there was a
problem, till my correspondent complains I did not sent him the expected
file or whatever.

I know, I appreciate the idea. :-)
I just try to explain the difficulties. I sometimes have to use one of my
providers smtp server, but then, is only one mail in a very long time
(fortunately), and have to send it from Mozilla, setting it up temporarily
not to use the local server but a remote one.
I know I can set up different transports for postfix based on recipient,
but the transport chosen must be selected from a pool based on the sender
address as well. That I still don't know if it is possible, and how.
Let me clarify further the issue.
I connect using a modem. The providers I use are also telephone companies.
It happens that in Spain, telephone calls are charged by the second (first
minute in advance), and that applies to internet dialup. Thus, the
providers get their money through the phone charges of the dialup calls.
In that environment, the "accounts" themselves are free. There is no
written contract signed by both sides. The user can be anonymous, in the
sense that the given name can be false.
It is possible to pay "flat rate", a month in advance, allowing to
use inet from 18:00 to 8:00, usually (ie, non peak hours). The
performance is very similar, and not really cheap.
I get only what they offer. Not being fully reliable, I have got two
accounts at two different companies (terra and tiscali). I have to be able
to work with either one transparently.
That means I have to use postfix to be able to send from one account when
connected via the other account, and also, to "send from" the rest of the
accounts that don't belong to any provider. There being no contract, they
are not under any obligation to accept email coming from an IP that it's
not theirs, nor with a different "from" address.
Or use only mozilla to send (and possible receive as well, pop before smtp
auth) using a diferent smtp server of each account.
