Hello, I was wondering if it is possible to setup a linux account to allow a login in the format <forename>.<surname> such as 'joe.bloggs'. When trying to setup a username $useradd joe.bloggs it flags an error, stating that this username is invalid. Is there a way that I can allow a pop3 login in this format. I've tried adding information to /etc/mail/aliases and /etc/mail/virtusertable i.e. virtusertable [email protected] joe.bloggs aliases joe.bloggs: joe-bloggs but that does not seem to work. Am I going about this the wrong way? Best Regards, Mark Starmer
