Unwhitelisted

3 more unwhitelisted messages allowed for this newsgroup until the end of its cycle.

One problem with that configuration is what to do about any wanted but unknown and unwhitelisted mail, which will be in that Junk filter buried in the spam which wouldn't be any fun to dig thru' to find.

The crutch of the matter is, Postfix is not *bouncing* this mail, it's giving a 4xx (temporary) rejection and inviting the client to try again later (which is what a greylist policy daemon would do anyway with a new, unwhitelisted triplet).

Note that my private addresses are unwhitelisted and yet have essentially zero spam.

The first time that an email from an unwhitelisted source has an unrecognized triplet the email is rejected and the triplet is added to the grey list.

I suggested compelling same-old-same-old helmet articles to carry the string "helmet thread" or suchlike in the Subject line, and when unwhitelisted people initiate such threads without such a string, explain the requirement along with an indication that it's a bit of a bleeding ulcer and here are the stock arguments.
