Interesting!

I believe they do it on purpose :-(

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.

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?

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.
