Re: I got those SMTP high CPU blues - guess why

Jeff, they got me about a month ago.  I turned off relay blocking several
months ago to test something (I don't remember what), and forgot to set it
back up.
One day I got a bounced email saying that an NT email server had rejected me
as an open relay.  I forgot about killing relay blocking and just kinda blew
it off as NT, then that afternoon, I was at the console doing something,
after hours, and the CPU started working like mad.  There shouldn't have
been anything going on, so I checked.  SMTP was real high on CPU.  I
suspected what it was, checked netstat, and ended SMTP long enough to freak
out whatever was abusing me, then restarted it and re-set up relay blocking.

I had to get ORDB to re-check me to get me un-blacklisted.

Can I just go out and set up my smtp server in an email client as just
anybody, without a userid/password on their system?  Does SMTP check? Or
just POP?  Or is there some more "hacker-type" stuff I'd have to know.  It
just seems like it'd be harder for a "professional" spammer to peddle his
trash.
