To set up a moble device, simply enter the information below into the device.
Email type = IMAP is preferred, but POP will work.
Incoming Server = imap.1and1.com for IMAP - if for some reason you must use POP, the incoming server will be pop.1and1.com
Outgoing Server = in all cases is smtp.1and1.com
Username and Password = Username is your email address. Password is the same as the one you use to access your email
Authentication = User Authentication for Outgoing Mail shoud use Username and Password (the same as your Incoming username and password). Some devices have an option for Same as Incoming; this works.
