I am anew user of Pegasus, and am running Windows XP2, using GMX email...I also run Outlook and Thunderbird, as well.
I can download mail with no issues, but cannot send out anything - keeps coming back as a delivery failure with the following message:
"Delivery has failed on the enclosed message for the following
reasons reported either by the mail delivery system on the mail
relay host or by the local TCP/IP transport module:
550 5.7.0 Need to authenticate via SMTP-AUTH-Login {mp-us005}"
Can anyone help me decipher this and explain how to fix this? Is it Pegasus or GMX causing the issues?
I appreciate any help I can get.
Thanks, in advance.
