This works great as you described, thanks.
Just for the record, I did the following:
Introduced new RCPT ACL:
warn !condition = ${if def:acl_m_valid_SRS}
verify = recipient/callout=20s,use_sender,defer_ok
set acl_m_valid_SRS = $address_data
condition = ${if def:acl_m_valid_SRS}
logwrite = Valid SRS address, skipping greylisting.
Then, I added !condition = ${if def:acl_m_valid_SRS} to the appropriate
greylisting stanza in the DATA ACL.
Best,
Peter
