I receive Unroutable address bounce back error message.

May 15, 2010     0 comments

The error "Unroutable address / Unroutable mail domain" is a general error which can be caused by several things:

  • A misspelled email address; for example, you have sent the mail to friend@laws-hyostun.co.uk instead of friend@laws-hosting.co.uk, please check very carefully the spelling of the email address of your recipient and try sending the message again;

  • You have a script that is expliotable by spammers;

  • The mail server cannot determine the correct route for sending your email message because of a DNS configuration error with the recipient's MX records; in this case the support for the remote server should be contacted for additional assistance.
