Almost five years ago, I became unable to post questions here by e-mail.
The
e-mail bounces with, for example:
The following message to <debian-user@lists.debian.org> was
undeliverable. The reason for the problem:
5.1.0 - Unknown address error 550-'5.1.7
<prvs=752320ad2=skdeb@syrano.acb.uc.edu>: Sender address rejected:

This commenced about the time my employer started prepending a bounce
address validation tag ("prvs=752320ad2=" in the above example) to my
e-mail address on outgoing mails. This fails with the debian lists but
nowhere else. I have circumvented the problem ever since by posting via
gmane.org.
