Exim4 ACL to reject a random 5% of non-TLS deliveries
Raw
exim_acl_reject_plaintext.config
## %5 rejection of plaintext transmission
## add to acl_smtp_mail or later (eg acl_smtp_rcpt, acl_smtp_data)
## change "defer" to "drop" to force a permanent rejection code
defer !encrypted = *
condition = ${if eq{${randint:20}}{2}{true}}
message = 4.7.0 Unlucky! Try STARTTLS command before MAIL
