But moreover, believe it or not I've found a fair
number of servers
that take the temporary rejection as a permanent one and never try
again. Customers won't accept this.
Customers have no choice. Greylisting is not the only thing that can
produce a temporary rejection...unless you're running a very
exceptional MTA!
Yes, I know it's easy to say in an ivory tower
mentality "well,
that's their fault", but in a business setting we don't have the
luxury of the ivory tower.
I actually think you don't have the luxury of not, in the long term.
It's decisions like that that are breaking email, worse than any
spammer overload. Tolerating nonconformance only encourages more
nonconformance. (I actually had someone use the term "broken spam
filters" for the filters I have in place that reject gross labeling
errors, like "text/plain; charset=ISO-8859-1" on mail containing octets
which are not 8859-1 printables. Just amazing.)
