RE: [PIUG List] E-mail spoofing - apologies

Hello, All,

Despite the many protective devices at our disposal, the sad fact remains
that, if you cruise the very public internet highway, hobo's will read
your tag number. what they do with that info is then pretty much out of
your control. The only totally secure system is the one that is entirely
locked down.

... such is the price of freedom and celebrity. I get junk mail all the
time ... Outlook filters work for some; the rest gets filtered to trash
the same as for the junk I fish from my US Postal mailbox.

wish there a better way,
rick

RE: [PIUG List] E-mail spoofing - apologies






Alan:

One of the problems with that approach is that, for a variety of good
reasons, sometimes a user can have different email addresses with
different domain extensions that don't match the sending ISP portal.
For example, my local ISP is dejazzd.com. and while I have email
addresses that end in @dejazzd.com, I also have addresses that end in
@ptd.net and @we-buy-books.com that I append to emails that I send
through my local ISP (dejazzd.com)

I understand the need to stem spam but the tighter you restrict your
rules, the more that legitimate mail gets throttled.
