Hmm. It seems, it sometimes does (look at the code for maprrouter() and
the handling of db expansions). I'm sure there are points in favour of not
removing duplicates, but it would be great if this could be configurable.
(I'd do it, but I'm just a beginner with zmailer, and I don't want to make
disastrous mistakes).

Thanks, found it, changed it, great :)

Well, it seems there is another problem. I prints the verifiyed address
just fine, but then emits "5.4.0 Unable to verify that address":

expn test1@uni-paderborn.de
250-Ursula Schwolle <ulla>
250-Swen Thuemmler <swen>
250 Ursula Schwolle <ulla>
501 5.4.0 Unable to verify that address

Another problem: this does not work from remote:
220 uni-paderborn.de ZMailer Server 2.99.42 #1 ESMTP+IDENT ready at Wed, 27 Nov 1996 15:23:44 +0100
helo linux.uni-paderborn.de
250 uni-paderborn.de Hello linux.uni-paderborn.de
vrfy test1@uni-paderborn.de
Connection closed by foreign host.

All I get is a closed connection :(

Yep, Sunsoft. Next compile will be with gcc.

Great. But I'm still puzzled by the warning from scheduler. According to
the manualpage, the expample code should work. Hmm.
