Using v.2.90, installed 20051024 --
When adding a new user through the Create Mailbox screen, the Primary Email Address does not get Enabled even though this is the default condition for the radio buttons.
https://...s.com:10000/virtual-server/edit_user.cgi?new=1&dom=1130293625...
save_user.cgi is called to process the form and the user is setup in the system, however the mail server will reject messages for the username@domain.tld. By going back into the user record and and once again using:
https://...s.com:10000/virtual-server/edit_user.cgi?dom=113029362526041&...
you'll find the the No Radio button is seleted. Change to Yes and click save. Mail server will immediately begin accepting messages for the username. Additional visits to the Edit screen continue to show the Primary email address enabled? as NO. But mail will continue to work OK.
I'll try and get a little time to look at edit_user.cgi and save_user.cgi, and will update my comments with a proposed solution.
