Hi there,

I'm using the Chilkat Mail Component (for C#) to send and receive mails using SMTP and POP3, both using SSL. Sending via SMTP works fine, but I keep getting an Authentication Failed - Error trying to get mail via POP3 - when there a special characters (like §,$ or Ä,Ö,Ü) in my password. When there is no special character in the password, it works. I tried to decode the password to UTF8 - doesn't work, then converted the password to a Base64-String (and using the PopPasswordBase64-Property), but that failed, too. (In every case of this, sending via SMTP works. Same user, same password.) Fetching mails via Thunderbird is working with those passwords.

Are there any restrictions to the Pop3-Password? How does it need to be converted or encoded?

Thanks in advance,

SVe
