Well, Eric mentions the problem of multiple 'Received' headers, which is true. If they were all packed into distribution format, there would be many header lines; but why not compromise? Any consolidation you can do on the mailer entries will reduce network load. Recall the 'exit type' as declared by mailer: Type 1 (DEFRT ) makes 1 copy per recipient... Type 2 (BITNET) makes 1 copy per node... Type 3 (BSMTP ) makes 1 copy per destination mailer Thus, if you have multiple nodes at your site (as most sites do) you should point ALL your :mailer tags to the primary mailer. With this minimum of effort you can condense multiple-recipient mail within your site to one copy, and it works fine with MG MODULE, provided you have the appropriate MAILLCL file. Beyond that would require custom profiles. If there was some simple means of just consolidating Bitnet<->EARN and Bitnet<->NetNorth traffic it would reduce the critical links between them. This would involve pointing all NetNorth nodes to CANADA01 on the Bitnet side, and so forth. This is probably too involved and complicated for a quick solution, but worth consideration, especially as it is in line with domain addressing. But you can consolidate your site mail NOW. And it is SIMPLE. And above all, it works. <Jeff> ****************************** * Cardinal Rule of Management, Number 3: * Walk softly, or your employees will hear you coming. * (National Lampoon, April 1987) ******************************
