I've noticed the following happening; Thats the ngrep transscript:
250-alioth.debian.org Hello postfix at mail.outgesourced.org [85.88.5.80].
250-SIZE 52428800.
250 HELP.
MAIL FROM:<room_0000000001.pkg-cita...@mail.outgesourced.org>.
250 OK.
RCPT TO:<pkg-citadel-de...@lists.alioth.debian.org>.
451 DEFER_IF_PERMIT Greylisted, see http://postgrey.schweikert.ch/help/lists.alioth.debian.org.html.
421 alioth.debian.org lost input connection.
And now the other part of the problem:
inside of the smtp queue these start to grow in numbers:
166796
23:1723:17w.goesgenspkg-citadel-de...@lists.alioth.debian.org
DEFER_IF_PERMIT Greylisted, see http://postgrey.schweikert.ch/help/lists.alioth.debian.org.html
any ideas?
