We send lots of newsletters and other subscription-type emails. Our qmail server seems to max out at 10,000 outbound messages per hour. I already have concurrencyremote set to 120, and reverse DNS lookups and other slowdowns turned off. The CPU (a dual UltraSparc) is not maxing out; it looks like we've reached a limit of the SMTP protocol and the number of connections allowed. I can see that separating outbound and incoming mail on different servers would help; most of the bounces come in while the bulk of the subscriptions are going out. We are going to add some servers, but I'm wondering if 10,000/hour is a typical limit, or is there some way I can send more messages in an hour? Thanks! ===== Greg Jorgensen Deschooling Society Portland, Oregon, USA [EMAIL PROTECTED] __________________________________________________ Do You Yahoo!? Yahoo! Messenger - Talk while you surf!
