Our users are experiencing problems setting up their membership using the public registration. They are getting messages that their email address is not valid when registering. We have tried setting it up for them manually. That doesn't work. We get the same mesasge even though we have picked sign up and go under vistors may sign up as site members. Is there a work around for this problem? Or is there a fix? Have attached the environment settings for the site. This problem does not occur with all company email addresses but it does with some....e.g. Name@mergerworld. com (i have substituted Name for user privacy.)
