Hi all, Could someone please help me with this problem? When I send email from the wijngaard domain to the sbomozaiek.nl domain the receiving server sais the recipient does not exist or the mail server is currently not accepting emails. This is the exact error message: <server01.wijngaard.local #5.3.0 smtp;553 5.3.0 j.hommes@sbomozaiek.nl>... No such user Any suggestions would be greatly apreciated. Regards, Johan Hommes
