Had a new box on the net for all of two hours, and this pops up on in my maillog: Jun 22 22:18:41 x sendmail[509]: WAA00509: SYSERR: putoutmsg (autumn.news.erols.com): error on output channel sending "250 <relayfinder@fnord.net>...

[207.96.89.34], stat=Deferred: Operation timed out with luser.oneill.net. It looks to me like someone on the host at erols tried to relay through me, and then mail the potential results to themselves at fnord.net (relayed via oneill.net). Is someone attempting to perform a community service here and scan the entire Internet for relays, or are they collecting relays for evil purposes? I can see it now; buy "10 million relay sites on a cdrom for $9.99". Ryan Brooks ryan@inc.net
