Temat: [exim] Problem routing dependent upon a whitelist
Hi,

I'm trying to write a router that will catch all emails NOT to OR from an email address on a white-list. I'm using a router rather than an ACL as I don't want Exim responding with a 500 error to the sender connection. Rather, just have Exim dump the email with a '/dev/null' transport (I'm writing an database email archiving tool for specific users).

The router definition is:


nonwhitelist:
debug_print = "R: not white-listed for sender or recipient"
driver = accept
senders = ! lsearch;/etc/exim4/local_MM_whitelist
condition = ! ${if eq {$local_part@$domain}{lsearch;/etc/exim4/local_MM_whitelist}{1}{0}}
transport = dump_mail
no_more

If the sender is on the whitelist, it works fine - but the condition to pick up the recipient - 'condition = ...' - always causes the email to be matched and dumped. (the whitelist is in ;/etc/exim4/local_MM_whitelist).

Any thoughts welcome.
