[LINK] Now that's secure - I guess

[David Boxall]

Every now and then, I get rejects like:
<bje at air.net.au>: host mailhub.air.net.au[203.11.71.23] said: 550 5.7.1
     <bje at air.net.au>: Recipient address rejected: Message rejected due 
to: SPF
     fail - not authorized. Please see
 
http://www.openspf.org/Why?s=mfrom;id=david.boxall@hunterlink.net.au;ip=180.181.128.93;r=bje@air.net.au
     (in reply to RCPT TO command)

In part, the openspf.org link text reads:
bje at air.net.au rejected a message that claimed an envelope sender 
address of david.boxall at hunterlink.net.au.

bje at air.net.au received a message from mp3.skymesh.com.au 
(180.181.128.93) that claimed an envelope sender address of 
david.boxall at hunterlink.net.au.

However, the domain hunterlink.net.au has declared using SPF that it 
does not send mail through mp3.skymesh.com.au (180.181.128.93). That is 
why the message was rejected.

I own a couple of domains and have accounts with several ISPs. Mail from 
all of my (potentially infinite) email addresses goes through skymesh.

I guess nobody who uses Sender Policy Framework will get messages from 
me, unless I use a Skymesh address.
