In PHPmailer is there anyway to remove the required “from email” address as your sending it?

I am asking because I am using it to send text through a gateway and the email characters count as characters and they are subtracted from the 140 we are limited to in a text. I want to put a shorter email address or maybe even a number.

    SMTP requires a sent from email address. It can be any valid email though.

    Check out the RFC for SMTP: http://www.ietf.org/rfc/rfc5321.txt
    I know its long and complex, however it should give you a good idea about what is required for email communication, and what you can omit.

    Since you need an email in the send from field, try something small like n@reply which is valid via the RFC 822 SMTP header format. (http://www.ietf.org/rfc/rfc0822.txt)
