'Limilabs.Client.IMAP.ImapResponseException' in Mail.dll

Answer 1

Please use:

imap.UseBestLogin(serverInUsername, serverInPassword)

instead of:

imap.Login(serverInUsername, serverInPassword)

AUTHENTICATIONFAILED means that Authentication failed for some reason on which the IMAP server is unwilling to elaborate. Typically, this includes "unknown user" and "bad password". Please make sure the password is correct.
