The documents that Paul referenced in his last message -
probably mentioned this somewhere - but I'll add that (in
addition to the link above and doing confirmed-opt-in "COI")
you should strongly encourage your customers to
captcha-protect their signup forms to prevent bots from
signing up spamtrap addresses.
That has been happening OFTEN in recent years - and those who
don't do COI and don't captcha-protect their forms (or some
equivalent only-a-human-could-have-done-this protection) - are
OFTEN getting blacklisted due to spamtrap addresses sneaking
into their distribution lists.
Is this deliberate enemy action or collateral damage ?
I'm finding it difficult to see why a general spam bot
would sign spam traps up to a mailing list,
so guess that I am missing something ?
