A quoted-printable message with a trailing blank encoded as you
describe has the same problem in Mailman through 2.1.9. I have fixed
it for 2.1.10.

Even if you had spelled out 'subscribe', your message wouldn't have
been treated as administrivia. In order to be administrivia, the
'subscribe' would need to be the first word on a line and followed by
no more than 3 additional 'words' on that line. Additionally, it would
need to be among the first 5 non-blank lines in the message body. So,
only the second 'su_______' would qualify except it is too far down.
