We have an e-mail issue where a mail sent from my company to joe...@joebob.domain<mailto:joe...@joebob.domain> bounces if REPLYING to joebob. If a new e-mail is composed and sent to that address, it works fine. E-mail from joebob to other domains (gmail, etc) can be replied to without issue.
Our e-mail travels though Frontbridge (Forefront) and I'm thinking it might be there, even though the error is: Requested #5.0.0 smtp;550 Requested action not taken: mailbox unavailable David Lum // SYSTEMS ENGINEER NORTHWEST EVALUATION ASSOCIATION (Desk) 971.222.1025 // (Cell) 503.267.9764
