What wildcards are supported in the Whitelist/Blacklist on MailWatch? I've tried the "*" but it doesn't seem to work.

Thanks Richard.

Appears I've found my answer over on the mail scanner faq. Apparently you can't use wildcards at all. Looks like my blacklist is going to get VERY LARGE.

Hmm....feature request? Or you can perhaps use a postfix rule instead since it allows regex and wildcards?

I'd be interested in any solution. As I've mention I'm not very good with Linux (yet) so I'd need a bit of schooling on how to.

It takes some tweaking in postfix, here's the post I saw that describes how to do it.

I'll highlight the important parts...

In /etc/postfix/main.cf...

smtpd_client_restrictions = reject_unknown_client_hostname,
check_sender_access pcre:/etc/postfix/sender_access
smtpd_sender_restrictions = reject_unknown_sender_domain,
check_sender_access pcre:/etc/postfix/sender_access

In /etc/postfix/sender_access
'
Reject anything from example TLD

Thanks, I'll post back results.

OK. The information you've provided. Is this added to the existing main.cf or does it replace the two lines in the file?
Also sender_access is blank. Am I adding the /\.example$/ REJECT ? Or what? What I want to reject at this time is China (.cn), Russia (.ru), Palau (.pw) and .asia. How would I format that into the sender access?

Thanks.
Richard

Went ahead and "added" the lines after the other smtpd lines and added /\.pw REJECT plus the others in the sender access file. Hope this is correct.

As a follow on is there a way to report number of rejected emails? By domain?

Thanks.
Richard.

FYI; .asia didn't get blocked. Do I need to restart anything?

Follow up, after configuring it blocked ALL email coming in so I know I did something wrong.

Feel free to share your postfix edits...

I followed the instructions in Shawn's link above, to block the .top TLD, and it worked without any problems. The sender_access file already exists. I just copied and pasted the additional four lines to the end of the /etc/postfix/main.cf file: and populated the sender_access file (which was blank) with I then restarted postfix, and no more .top messages.
