While we're talking wanted features, I'll point out that TLB allows
configurable sized batches, or a fixed number of batches, or N addresses
per batch, or N domains per batch.

TLB sorts by reversed domain, if desired.

But what's the threshold?  One domain per batch, period?  (TLB can do that,
if you like lots of Sendmail processes.)  All domains appearing twice or
more in their own batches, everything else split into groups of N addresses
or something?  That would be an interesting addition.  Perhaps I'll add it.
