Hi HGW, some security software can interact with Outlook in weird ways. I found the following regarding Avast (support.avast.com/.../
"If you use an email client (such as Outlook or Mozilla Thunderbird), Avast may include an email signature at the bottom of your outgoing emails to let your recipients know that the email has been scanned for malware. This setting is enabled by default."
Disable the Avast email signature for outgoing emails and try sending a few more test messages. If you still get the 552 5.2.0 error message, disable Avast completely (just in case we're overlooking another Avast setting or tool that is impacting Outlook) and try again. Please let us know what happens! -Becky, Cox Support Forums Moderator

Hi, Becky, Avast was disabled and could send one test message, after that blocked again with same message from Cox. What now?
