535 relay not permitted - Incorrect authentication data

    535 relay not permitted - Incorrect authentication data

    Hi,

    I am running Pegasus Mail v4.41 on Win XP and have for some days troubles in sending Mails. Receiving mails works (sending and receiving mails using the webmail-interface is ok also).

    After sending a new mail I get a window with the error "Incorrect authentication data" and shortly after that I get the message back with "Mail Delivery Failure - 535 Incorrect authentication data".

    I contacted my ISP to make sure to use the right server, port, login name and password (login name and password are the same for the webmail-interface and there it works). I also sent them the connection log. They told me a) to use SMTP Authentication and b) to disable CRAM-MD5-Encryption.

    I activated the SMTP Authentication with <username> and <password> but I still get the error.

    Now I don't know how to disable CRAM-MD5-Encryption. Is it possible? If so, how? If not, what else can I try?

    I searched the forum - especially for "535" and for "CRAM-MD5" but I couldn't get an answer that works for me.

    Can anyone give me some helpful advice?

    Thank you very much,

    Peter
