Problems while joining/leaving this mailing list

[Ralph Seichter]

I have written to the list owners but did not receive a reply yet, and I
also wonder if anybody else has experienced this:

I tried to subscribe with new at dom.ain and unsubscribe with old at dom.ain
by sending email to gnupg-users-request at gnupg.org from each of this
addresses. Firstly, I find it very irritating that messages to the
mailing list robot are subjected to greylisting delay of at least one
hour. Secondly, I have received two replies with different confirmation
codes for each of my (un)subscription attempts -- four codes total.

It seems to me that the mailing list robot is experiencing hiccups. Can
anybody here confirm this?
