acl_check_rcpt problem and Blank FROM address

Helo everyone

I recently installed a new exim-mysql server and made provision for users to
log into a web frontend and define their own denied senders and denied
domains.

But I have discovered that some emails get delivered to some clients and the
from field is blank. (F=<> in the log file).

This causes my server to reject the email with a 550.

Here is what I have in my ACL:

deny message = Sorry, I am not allowed to deliver mail from
($sender_address) to ($local_part@$domain).
condition = ${if eq {${lookup mysql {SELECT sender_address FROM deny_senders
WHERE sender_address = "$sender_address"
AND local_part = "$local_part" AND domain = "$domain" AND active =
"YES"}}}{$sender_address}}

So I see many emails get rejected with:
Sorry, I am not allowed to deliver mail from () to (someone@somewhere.org)

Can someone please tell me what the best way of fixing this is.
Should I add another ACL above this one which will accept the email if the
FROM field has a bank value, and if so, what should it look like?


Thanks in advance

Wayne

Hi Everyone

Got it working:

accept
condition = ${if eq{$sender_address}{}}
