Currently pigeonhole supports reject which would generate a NDR for each message. (If I understand the current documentation)
Using Dovecot LMTP it would be more optimal to kick a 5xx back to the primary MTA to reject the delivery rather than generating more back scatter NDRs. Anyone know if this is possible now (to forgo the NDR)'s or do we need to wait for ereject ? If so, how much work is involved? -- Robert inoc.net!rblayzor http://inoc.net/
