Can you only send out email from the username specified in the ActionMailer smtp_settings?

I would guess that this is more of a SMTP issue that it is ActionMailer. Some SMTP's do not require Username/Passwords to send outgoing mail and so you can set the From address as you like.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
