It would be enough if SIMS had a toggle for this. Mail claiming to be from mail.hotmail.com that resolved to foo.barr would be rejected, but mail that claimed to be from mail.hotmail.com and was from foo.hotmil.com would not. I certainly wouldn't want a broken SMTP that rejected mail because the server names didn't match exactly. > But I don't see this (or any other feature) being added to a future > version of SIMS because, I hope I'm mistaken but I don't think there > will be any further version of SIMS.
