300 is not a standard code. The real error code was 554 (earlier in the message). I don't know about other MTAs but in Postfix when you configure reject reasons you can put any text in the message at that point. The '300' is probably meaningful only to whoever set up the server. -- Jim Garrison (j...@acm.org) PGP Keys at http://www.jhmg.net RSA 0x04B73B7F DH 0x70738D88 _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
