It seems like we are doing something wrong. We are using exim on a
whm/cpanel setup to filter spam for another server for a few domains.
By default in recent exim config file, the recipient verification is
turned on for non local domains:
#recipient verifications are required for all messages that are not sent
to the local machine
#this was done at multiple users requests
require verify = recipient
message = "The recipient cannot be verified. Please check all
recipients of this message to verify they are valid. Details:
$acl_verify_message"
I am just trying to add "/callout=20s,defer_ok" next to the recipient
(entire line looks like this: require verify =
recipient/callout=2m,defer_ok). Here is what we get as soon as we apply
the new config:
<hidden@validsender-email> temporarily rejected RCPT
<hidden@validrecipient-email>: expected "sender[=address]", "recipient",
"helo", "header_syntax", "header_sender" or "reverse_host_lookup" at
start of ACL condition "verify recipient,defer_ok"
Any help would be greatly appreciated.
