How to test the validation function of batv-milter

[kinglok]

Hi Andrew,

Thank you for developing batv-tools. I've managed to install batv-tools ver 0.4 to the postfix 2.9.6 on the debian wheezy mail server. I run batv-tools as milter in postfix.

/etc/postfix/main.cf:
smtpd_milters = unix:private/batv-milter
non_smtpd_milters = unix:private/batv-milter

When checking maillog, I can see the address is signed with "+" subaddressing correctly. But how I can test the validation function?

Here is my test case:
I've tried to send to an non-existent gmail account and there is no X-Batv-Status in the email header in the reply email. How can I trigger it?

Thanks a lot for attending.

Hi,

Is the test bounce coming from the same postfix server that's running batv-milter? If so, the problem is that by default postfix doesn't apply milters to bounces that it generates itself. This is actually OK for batv-milter because you can trust any bounce from your own server. For testing, you need to cause a different server to generate a bounce to you. I should set up a special email address people can use for this, but in the meantime I'll privately email you an address which I know causes bounces.

It is also possible to make postfix apply milters to its own bounces by setting the postfix option internal_mail_filter_classes = bounce. However, the postfix documentation says "It's generally not safe to enable content inspection of Postfix-generated email messages. The user is warned." I only learned about this option recently and I'm planning on asking the postfix developer why this option is not safe before I recommend that people enable it.

Hi,

Thank you for replying. I confirm that there must be internet_mail_filter_classes = bounce for checking batv status of the bounced mail from other server.

Thanks.
