Re: [Exim] combined conditional statements

I use something similar to check and see if there is a valid sender domain

and MX record because I would rather deny at rcpt rather than bounce on
delivery

deny message = Bad E-Mail Address $local_part@$domain!\n \
               Cannot Find Mail Domain: $domain, or MailHost Record For: \
               $domain in DNS search.\n Check The Email Address and Try
Again
    domains = !+local_domains
    set acl_c4 = ${lookup dnsdb{a=$domain}{$value}{NO-A-RECORD-FOUND}}
    set acl_c5 = ${lookup dnsdb{mx=$domain}{$value}{NO-MX-RECORD-FOUND}}
    condition = ${if and {\
                    {eq {$acl_c4}{NO-A-RECORD-FOUND}}\
                    {eq {$acl_c5}{NO-MX-RECORD-FOUND}}\
                    }\
                    {yes}{no}}

 but I would think


    condition = ${if or {\
                    {eq {${lookup dnsdb{a=$domain}{$value}{NONE}}}{NONE}}\
                    {eq {${lookup dnsdb{mx=$domain}{$value}{NONE}}}{NONE}}\
                    }\
                    {yes}{no}}

will work, but I would still make that ${if and{\  if you are looking for a
way to check for undeliverables
