I know that Roundcube is imap, but the set-up on T-Mobile also asks for a port number in addition to imap. I am not a super techie, so I don't know why the port is also needed.
sorry but this is info you should not get from a maillist that is unpaid :)
imap 143 pop3 110 imaps 993 pop3s 995 smtps 465 smtp 25 submission 587
imaps and pop3s can use ssl / tls as to get this to work, currect settings is comming from you mail provider, not maillist :)
