I'm using SA-Exim 4.12/2.2, SA 2.60-CVS.

1: My own ACL rules for the above are quite unlike those you quote - and
mine are "lifted" directly from the original. Best is, that the
originals work perfectly.

2: Unscanned mail should go exclusively to postmaster or abuse and the
sender should only get one chance to do this. Exim 4.12's present ACLs
are perfectly capable of coping with this.

3: This is Marc Merlin's baby, IMHO, and *no-one* else's. All questions
about it should be addressed to him, or those monitoring SA-Exim results
daily, especially when quoting his config directions. There's always his
dedicated mailing list for this.

Best,

Tony
