Hardly.

Postfix works and isn't particularly hard if you take the time to read and
understand the docs.

The point is, an mta is something you need to set up. Be it sendmail, exim,
postfix or exchange.

then you set it up. Nothing shocking here. This is a normal step in
provisioning a host. It's like not specifying an alias for the local root
account to send system messages somewhere else where they get read. and the
local root account accumulates messages nobody reads. Then you login to run
some maintenance and the first thing you see is 20000 unread messages.

RTFM :-)

It is not that hard:
http://www.postfix.org/BASIC_CONFIGURATION_README.html'What delivery
method: direct or indirect'.

Or http://lmgtfy.com/?q=postfix+how+to+send+mail+through+isp if you think
the docs are hard to find, then you get a link to the postfix.org site
http://www.postfix.org/SOHO_README.html where you can read 'Enabling SASL
authentication in the Postfix SMTP/LMTP client' to relay e-mail to another
server with authentication enabled. Very easily explained.

Of course you can always find an obscure howto somewhere on the net and
then complain that it does not work. I prefer to stick with the official
docs.

Running an internet facing stmp server is another matter. But running
postfix with a smarthost is a piece of cake.

I mean, simpler than

relayhost = yourispmta.domain.tld

 is hard to find, isn't it?
