How can I block mails fom host without DNS name and valid MX?
I check sources for qmail-toaster and I find CHKUSER_SENDER_MX is defined in
chkuser_settings.h. Why not block host whitout DNS?
I do on my production servers, and also block non existent rDNS sources.
I get complaints all the time from other admins who do not have rDNS set
up. Some people are for it, some are against.
Obviously on the mailing list I'm a little more lenient since if you're
asking questions you probably have a problem (that is 99 time out of 100
a configuration issue) and would probably not be able to send to the
list otherwise.
