Bug#1041073: exim4: Add CLI option to retry delivery for a particular recipient of a mail

[Matthew Vernon]

Source: exim4
Version: 4.96-15
Severity: normal

Hi,

The exim CLI tool has a number of options for selecting particular
messages for {,re-}delivery attempts; but in all cases it will retry
all undelivered recipients of those messages.

It would be nice to be able to specify a subset of undelivered
recipients to retry - e.g. "attempt delivery of message XX-YY-ZZ to
reciepient foo at bar.com".

I sometimes find certain large mail providers get unhappy with
messages that contain a number of their recipients on the same mail,
and being able to just try to deliver to one or two of them at once
can help unwedge stuck mails...

Thanks,

Matthew
