i'm aware of this common convention (without commenting on how useful it
is at actually defeating spammers), but i'm surprised to see it
happening with two mail servers that both have sent messages to GnuPG
mailing lists in the not-too-distant past.  it's possible that both of
those mailservers have changed at the same time, i guess.  there
certainly was a recent change for my own mail relay.
