I have a AUTHINFO file in my mail directory that have the usernam and password information.
AuthInfo:localhost.localdomain "U:root" "I:myuser@att.net" "P:password" "M:LOGIN PLAIN"
AuthInfo:localhost.localdomain "U:user@verizon.net" "I:user@verizon.net" "P:password" "M:PLAIN"

I am using DNS from --> no-ip.biz.
define(`SMART_HOST', `smtp.verizon.net')dnl define(`RELAY_MAILER_ARGS', `TCP $h 465')dnl FEATURE(authinfo)dnl
