Hi, I tried to create an email account with the name firstname.lastname@example.org. On ISPConfig - User &Email, the username is prefix as web1_ . Is there anywhere I can fix this not to have a prefix? I just need username as dstme instead web1_dstme. Please help, thanks again. I have another problem, I tried to test sending email from one account to email@example.com but failure notice return. But there is no problem sending out from firstname.lastname@example.org using ISPConfig. Any thing that I set wrongly on ISPConfig?
