Access Policy Email Agent does not send email if the remote server does not provide a 200 OK response to VRFY request.
The Access Policy Email Agent does not send mail messages or log an error about mail not being sent.
The version of CURL included in 13.0.0 uses VRFY requests to confirm recipients are valid before sending mail. Many servers consider VRFY a potential leak of information and will respond '252 - Not verified' and the BIG-IP system will not send the message.
None.
The APM Email agent no longer attempts to verify recipient addresses and will blindly send emails to the requested addresses. This is correct behavior.
The APM Email agent (v13.1.0 and later) will not verify recipient addresses before sending email messages. This is correct behavior.
