A day or two ago I tried sending an email to a friend who happens to use the Road Runner ISP for his mail service. Now this ISP doesn’t like dynamic IP addresses (using the increasing inaccurately named Dial Up List) so I have to punt the email through my ISP’s mailserver first. Now that server is telling me this:
The reason for the problem: 4.3.2 – Not accepting messages at this time 554-‘5.7.1 – ERROR: Mail refused – <18.104.22.168> – See http://sendersupport.senderscore.net’
So their ISP mailserver is refusing connections from my ISP’s mailserver for some reason, probably on some spam list. There’s a URL to look up the problem, so going there gives you three things:
- A redirection to https://sendersupport.senderscore.net/
- A badly configured webserver that uses the above URL with a certificate for www.senderscore.net
- A page that says “It works”
Either Road Runner or Senderscore, preferably both, need to get a clue. Oh and going to https://www.senderscore.net/ gives connection refused. A bit of digging around shows the correct URL is https://senderscore.org/
Now I just realized that my SSL certificate for https://enc.com.au/ expired on the weekend so I know these things can happen, but I’m one person (who was away for a while), why can’t companies get their act together?
