Hi all
I hope this question hasn't been asked before...

Our mailprovider is going to change its smpt-behavier concerning mail relaying.
Actually we use one single smtp-account to send mails from any of our mail-addresses.

The mail provider wants us to send each mail with the individual(!!) account of each sender.
I hope this issue is clear

I have found some descriptions with different relay host for different domains.
For example pommes@mayo.de via smtp.mayo.de and mayo@pommes.de  via smtp.pommes.de
But nothing how to use an individual account.
Maybe i do not know what to search :-)

Any help welcome.
