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
