Umm, that's not XML.  It appears you sent your mail as html mail, but in
a manner that renders poorly when html is stripped (most people read

Also, pastebin content tends to be transient; if the output is short, it
would be better to paste it into the body of your email, so that it will
survive in the archives alongside your email instead of suddenly
