[IMail Forum] VALFROM failure

[Matt Warren]

Hello,   We have been having issues with receiving xml attachments recently from some users.  To test I sent out the offending xml file through our iMail server to my home isp account and checked the headers.  One that sticks out is:   X-IMAIL-SPAM-VALFROM: (b29700a300001fa8)    Which I found by definition means: The message failed the “MAIL FROM” address validation.   I am not too familiar with how to interpret this information.  Can anyone point me in the right direction?   Thanks!   Matt Warren IT Technician 414-847-1207 Ken Cook Co.
