Yes – I suspect that SPAM filters are to blame for “missing emails” when you don’t get a bounce or undeliverable response.
They vary from filters on Microsofts outlook, to commerical parsing engine to subscriptions to brightmails anti-spam service. (where they block known spams)
:shooter:
I use the latter and it’s stemmed to torrent of SPAM at my published email addressesfrom 250+ per day to just 30 or so. And probably half of those are SPAM that hasn’t ben identified yet.
