How to define the Logon-User-Name for the Mail-Server?

I need to know, how I can store the Logon-User-Name for the Mail-Server, when that is different to the EMail-address?

Thank you very much!

Hi,
that depends on your account type, you can change your authentication credentials in Tools > Accounts under the respective POP/IMAP/SMTP/AirSync/Mail tabs, by changing the option from ‘Use identity credentials’ to ‘Use these credentials’ and writing down your logon user name and password.
