When a user tries to register on our forum. They get the following error:
"mail() [function.mail]: SMTP server response: 550 <emailaddress> No such user here in E:\inetpub\vhosts\ryarc.com\httpdocs\forum\include\email.php on line 105"
If I switch off the option to "Require verification of all new registrations by email" then it works fine, but obviously we need to leave this option enabled.
I have tried removing the smtp settings as per suggestion in a similar post http://punbb.informer.com/forums/topic/ … ail-error/ but this does not change anything.
I would appreciate any suggestions on what to chech or how to fix this issue.
Thanks
