acl_check_rcpt:
warn domains = yahoo.com
set acl_m_yahoo = true
acl_check_data:
deny condition = $acl_m_yahoo
condition = ${if >{$message_size}{5M}
message = Your message has a Yahoo recipient and is >5MB
The trouble with this is that if a message has multiple recipients that
have yahoo and non-yahoo addresses, then the non-yahoo addresses will
also not get the email. You could of course see that as a feature rather
than a problem...
