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.
