Wasn't meant to be derogatory or anything but having to send each mail
several times with slightly different wording, layout, subjects as they
keep bouncing due to being detected as spam is quite annoying.
I see two blocks from you in the logs - both because you were sending
email with a disclaimer. The last one was July 3.
If you think you are being blocked inappropriately, do what the bounce
message tells you and send email to postmaster. And, if at all possible,
leave out words like "annoying" and "broken".
