We know we have a problem. This problem was detected on 14 July and we're working on solving it. Before 14 July our e-mail system was OK. Yes, we've been blacklisted before. But definitely not continuously. If it had been continuously, it is logical we wouldn't have been around any longer - sort of makes sense doesn't it?
The bulk of my correspondents are on ATT systems and the periodic tests I've made to them since 2014 have always bounced with the same blacklisted-IP error message, so I reasonably assumed the problem there was continuous. When I mentioned it last year, you said it wouldn't be corrected until you got some different IPs this year, in January, IIRC. I tested again at that time and the mail still bounced and it does as of today.
Other majors handle what they misperceive as spam in proprietary ways that remain mysterious to me. Gmail vaporizes some putative spam and passes others to the spam box. Why? I dunno. Etc., etc., etc. To some extent this stuff remains an unavoidable pain for most email users.
Ours is a shared server with an overall majority of WordPress and Joomla Websites, notorious for being hacked and infected. A large percentage of our customers are here to try out new things and do make mistakes as they go along. So there is no guarantee we won't be blacklisted again. As such recommend if you are looking for a spam-free e-mail service that you look for e-mail hosting elsewhere.
I understand this, which is why I have kept my parked site monitored, comment-blocked and religiously security-updated so I wouldn't be part of that problem, as I know from my logs that these sites are maliciously probed pretty much nonstop. So far, mine's stayed clean as far as I can tell.
I wanted to use my own Gigarank site's mail system purely for the control it would afford me over that of my ISP and other mail hosts which are becoming more and more intrusive, inconvenient and obstructive. Doing mail here is fast and trouble-free from my mail client, but delivery to my correspondents is weirdly unpredictable, except that it's predictably never reached those on ATT's mail systems.
This is why I asked about this. I had assumed that these were low-priority issues you had forgotten about.
