Re: [IMail Forum] Time to fix "Refuse NULL <> Senders" option! on Saturday
10:15:07 AM
We have turned this on several times only to see listserver
emails blocked that were legitimate emails. We liked the spam
that was blocked, but along with it we found tons of emails
in our log that were legitimate listserver emails. At first
we thought this was all spam, but upon closer look we found that
many listserver or newsbot emails have null senders, including
many from the likes of ZDNet and other major news organizations.
So look closely, with null senders on, you may be blocking
legitimate mail.
