I believe they do it on purpose :-(

Can't help you there, I'm afraid.

I know, I know, I'm just grumbling aloud, letting steam out.


Worse, all Spanish ISP's and mail accounts I have do the same, meaning I
can't relay any of my redirector addreses like sourceforge or ieee.

It would probably be the best solution to use a virtual private server,
they cost about 10 Euro per month, that will give you a fixed IP, correct
dns/reverse dns and probably a domain name of your choice.

I have thought of that, but the expense is not justified (yet).


/etc/postfix/sender_relayhosts:
user@xxxxxxxxxxx [relayhost]

But... I have a doubt. Will that relayhost be used for all mail sent from
user@xxxxxxxxxxx, or only to those destinations in the transport file?

Yes, it will be used solely based on the sender address then (if the
address is found in the sender_dependend_relayhost_maps).

Pity. Seems I can't get all :-}


Meaning, I want to send all my email direct, except to those destinations
I define in the transport file which sould use a relay choosed on the from.

Alternatively, send always via relay defined in sender_relayhosts, except
to some destinations I want to send direct.

Okay, this might get really geeky and cumbersome, but you could
theoretically set up two instances of Postfix (not listeners!), where the
first instance is trying to send directly with "soft_bounce=yes" and
fallback_transport = smtp:[ip-second-instance], so rejected mails will
will be transfered to the second instance.

This instance knows, that all mails have to be relayed via a relayhost, so
it is configured to use sender_dependent_relayhost_maps with soft_bounce=no.

Uau...

That would probably do most of what you want to achieve, but it is quite a
bit of overhead to set up and manage. I have a few doubts, if it is
really worth the effort.

Yes... very doubtfull... :-?

My current procedure is easier to maintain: change the configuration when
I have to send an email trhough a different route. And, it wouldn't solve
the problem of sending emails with redirector aliasses.

The advantage now is that I have learnt a an alternative place to set it
up, based on "from" instead than in "to", and I can at last use a method
to relay (almost) everything. I could create now an script instantly
setting up/down relaying. It's something.

Another method would be to have a fixed IP, and use it for sending, but
that would be a different can of worms, I guess.



Got it, thanks. :-)

Okay, unfortunately I've seen too many ISPs who silently delete unwanted
mails.

Me too :-/

At least, my main one doesn't do it, but someplaces I send to do. They
accept the email, but it never reaches the destination. Worse, their users
think that the problem is mine because I'm a geek or something. Of course,
as I use linux, I must have done something wrong. :-(

Nowdays, email is less reliable than surface paper mail.
