Ok, i've read the stuff about Pop3/Imap configuration for email clients, but i'm none the wiser - i cant get it to work in Windows Mail.
In virtualmin I added a new user through the Edit Users section. I also enabled Mail Client Configuration under the Email Messages menu.
In Windows Mail i've put mail.domainname.com for both the Incoming Mail (Pop3) and Outgoing Mail (SMTP) fields. In the Email Username field i put the username as it appears in Virtualmin, (i.e. user.mainuser). And obviously i put the password i just set in virtualmin for this new user. I select 'Logon using clear text authentication' and I check 'My Server requires Authentication'.
But this isnt working for me - the Windows Mail error says the host mail.domainname.com could not be found.
Not sure what i'm supposed to do here - is there something else i need to install in virtualmin for email to work, or is mail.domainname.com the wrong structure to use in those Pop3/SMTP fields?
