I try to configure routing on my home MTA. It should send every message using
relevant smarthost, e.g. message from ichthuss@??? using
smtp.gmail.com, message from foo@??? using smtp.mail.ru etc.
I have several accounts on some servers, so authenticator for smtp.gmail.com
should use different user names and passwords, depend on "From:" message
header. But I can't find a way to use sender address in authenticator (like
$address_data in transport). So, is there way to use several accounts on same
server, depend on sender address?
