I see no manual about what available options can be configured when sending email form the router. The obvious - server, from, to, subject, body.
What if I need to use "smtp auth" to send mail to the mail server? Especially if you cannot use a static IP on the router WAN interface and therefore cannot be authenticated via IP address?
I see no detailed documentation on the "e-mail" command. Please advise where I might find out more and if smtp auth can be supported.
