For what it's worth I always make sure the sender verification rejects
at the recipient.

deny    message = REJECTED - Sender Verify Failed - The email server for 
the domain [$sender_address_domain] tells junkemailfilter.com that the 
sender's email address [$sender_address] is not a valid. 
$sender_verify_failure
        log_message = REJECTED - Sender Verify Failed - The email server 
for the domain [$sender_address_domain] tells junkemailfilter.com that 
the sender's email address [$sender_address] is not a valid. 
$sender_verify_failure
    !verify = 
header_sender/callout=2m,defer_ok,mailfrom=sender-verify@???
    condition = ${if eq{recipient}{$sender_verify_failure}}
        condition = 
${lookup{$sender_address_domain}wildlsearch{/etc/exim/acllists/noverify.txt}{no}{yes}}
        condition = 
${lookup{$sender_host_address}wildlsearch{/etc/exim/acllists/noverify.txt}{no}{yes}}
