Whether I can make such a policy stick is another > question entirely. I sent more than 20 mails in the last hour. Given that I have a local mta each of those results in a seperate connection attempts to the machine I use as smart-host. I'm sure I could batch them all up and send them at once thereby returning to my uucp days, but bleh, that really breaks up the pattern of back-and-forth communication that we've gotten used to. There's a bunch of forces pushing in various directions that make email less usable for me and I assume everyone else... The big one is spam, restricitive mta behavior is another, and there are others. When my mta becomes more selective about what senders I choose to accept mail from or in this case when or how often, then eventually I lose mail from people I would otherwise have communicated with. That's frustrating becuase it's as disruptive, if not more so than having a mail box full of crap. Eventually I suspect I'll be forced to abandon the rfc2821 email system as a communications tool entirely, and brick myself up in the cellar, but I actuallly liked it as a tool when it worked. joelja > -- -------------------------------------------------------------------------- Joel Jaeggli Unix Consulting [email protected] GPG Key Fingerprint: 5C6E 0104 BAF0 40B0 5BD3 C38B F000 35AB B67F 56B2
