I thought verify=sender did a callout to the sending server to verify that
the sender existed.
The spec:
verify = sender/<options>
This condition is relevant only after a MAIL or RCPT command, or after a
message has been received (the acl_smtp_data or acl_not_smtp ACLs). If the
message's sender is empty (that is, this is a bounce message), the
condition is true. Otherwise, the sender address is verified.
Did you mean verify = recipient
