Yes, it should be a "simple" fix in sendmail....

However, when you are in "cloud computing" things are not that simple.

Your issue is noted and I have discussed email errors with the ISP in the past with no definitive resolution as I cannot correlate complaints with specific log entries from the server side.

That specific point does need to be resolved and now that I have a definitive error message from a user log, I may be able to get it corrected through the ISP.

Keep in mind, when I look at email error logs, I am looking at more than a thousand entries per day. My sampling has noted they correlate to know spam sites which means I do not worry about them.

Thanks for your log entry.
