If 587 is always auth'ed; then there will be no spam splashback provoking calls to block it. (Individual customers may get zombied; but that's easy to track and treat...) If a provider runs an open 587 port, and thus gets used as spam source; they will soon meet Mr. Linford and/or Mr. SPEWS. In either case, why will the clued ISP's want to block 587? -- A host is a host from coast to [email protected] & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
