sending mail from ruby...

[sergio_101]

i am having problems sending emails with ruby on rails.. it seems that this problem has just sprouted out..

when the system sends out an email, my log shows this:

Net::SMTPFatalError (550-"The recipient cannot be verified. Please check all recipients of this
550 message to verify they are valid."
):

it appears that exim is verifying that the address is valid first, then sending..

the addresses that i am sending to are valid and they work...

does anyone know either:

how to address this problem

or..

how to turn off this verification?

thanks!
