I mean an address like '[EMAIL PROTECTED]' which, if you received a probe for that address, would not cause _further_ callouts. To do a header_sender callout with a null sender is broken, as Steve B discovered. The RFC2822 sender address may never be used as an RFC2821 sender, and may reject all bounces. -- dwmw2 -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
