As you've been very helpful in the past, can I ask the best way forward in addressing this problem.
In an attempt to reduce spam delivery to a local charity mail server, I added
FEATURE(`require_rdns')dnl
to the sendmail config. It did help. However, it also blocked some important clents as well...
barnardos.org.nz - sends via 122-56-8-123.cid.global-gateway.net.nz logon.i.govt.nz - has no IP address ecan.govt.nz - sends via onyx.crc.govt.nz which has no IP address
whitelist. Though those govts should have an public facing dns entry... but a quick search back though the archive would show that there are some big providers with helpdesks that fail that one, so again... white list. D
probably being the most important.
How do you address this problem. I'm certain they all must have been repeatedly contacted?
TIA for all ideas,
Steve
