We are currently programming an application to handle our email since commercial email programs (i.e. Outlook, etc.) don't cut it anymore for us. Does anyone know what security mechanism is required to make a successful connection via SMTP to ESMTP Exim 4.69?...
We've tried Indy 10's OTP, MD5 and SHA1 hashes, and use the same settings we have in Outlook, but we keep getting the following message when we try to connect to the SMTP server through our application (our account works fine with Outlook):
220-We do not authorize the use of this system to transport unsolicited, and/or bulk e-mail.
Any help, comment, hint will be appreciated...
Note: we are newbies at programming, please be kind...
This is the full response from the mail server:
