Well, my opensuse alias is not in the logs, that's whey it passed. So, it is using my ISP "from" in the envelope, but the "from" header is my alias. Not something you can do on the MUA...
Yeah, I guess most MUAs will use the same address in the envelope and in the header. You could do it with some magic in a local MTA.
I think tricks for doing that were posted years ago on the old suse mail lists, because the list server checked the envelope address only.
My trick is to send via another /ISP/, gmail. Gmail has an automatic form you can fill to authorize an account with them to send for another address.
Ah, problem solved.
Yes, of course.
My intention was solely to remind those with a fine mail provider that not every provider works that way. None of the different mail providers I have tried in Spain allows sending with a different "From". I have to use an American mail provider. Sorry for the confusion.
This has caused me many problems in the past, because Postfix did not support the situation. There was one relay host and that's it. Now, there is a configuration in postfix that tells which smtp server to use for each different from, and what password to use in each case.
