Perhaps Chris could send you the email settings he uses (off list)? I host my own mail server but send most * of my emails via my ISP's smarthost.
The details I use for sending via the Smarthost are details that were current years ago. They are no-longer listed, but they still work. Chris's settings may not be listed but may be valid and usable.
Thanks for the suggestion Steve (Chris, over to you).
[* my email server allows different smarthosts for different destination addresses]
Do any of the people you buy services from have an email smarthost you can use?
My domestic ISP (Plusnet) may have a relay host (or so it would appear from the support forum discussions between customers, even though they don't advertise it) but that would mean me tying myself to their infrastructure when I may not stay as their customer in future. And it might also mean that I would have to move my mail server onto my internal network when I already have a good, fully functional server on the wider internet.
None of my VPS providers seem to have a relayhost service (which is odd, because Hetzner in particular could probably benefit from one).
But one piece of good news is that Mimecast have at last responded positively to my request that they look at their blocklist and they say they have de-listed my mailserver (not yet tested though). Cloudmark have (auto)responded to my request for the IP address to be checked saying:
"Please note that after the reset, Cloudmark will continue to gather statistics for this IP address. If spam is still being sent from this source or if we receive additional spam complaints for this IP address, its reputation will be negatively impacted.
Please be aware that you will not receive a notification upon remediation of the IP. If we require additional information, we will contact you."
But of course there was no spam from this server, they simply blacklisted the IP address, so I am hopeful that the problem at ntlworld will now be fixed.
(Now just checked and I can send to ntlworld. Hooray for common sense.)
As a last resort, which I'm sure you won't want to do, but I believe that you can send via GMAIL. You'd have to set it up for each of the email addresses you want it to send from.
No - I won't go there. I am still exploring the paid for third party relay mechanisms though - they may yet be necessary.
