All Dynamic IP addresses blacklisted by Trend Micro!

[MrFizz]

My emails to two colleagues in France have just started bouncing and when I investigated I discovered that I had been blacklisted by Trend Micro. When I followed Trend Micro's procedure for requesting removal from their blacklist, I was told that they refused and stated "we need the IP to be static in order to remove it in our list". As most home PCs/Laptops use dynamic IPs, there must be billions of home users with dynamic IPs (anyone know how many?) and, according to Trend Micro, they could all potentially end up being blacklisted black-listed, bringing email communication for ordinary people and professionals who work from home to a crashing halt. Is this even legal? How on earth can I extricate myself from this situation before I lose more email contacts?

TrendMicro is entitled to blacklist whatever IPs it likes, just like it's entitled to bundle AiProtection on Asus routers even though it's so badly written it causes Kernel Panics on many of those routers!

if you've paid for a Trend Micro service and you believe you can justifiably claim that it's no longer fit for purpose you may well be able to claim at least a partial refund!

Are you using a VPN? if so it's more likely that it is that which has been detected and blocked

[MrFizz]

No, never use VPN, and I have had a couple of back & forths with Trend Micro, when they have never mentioned anything other than my dynamic IP being the problem.

[Crimliar]

The thing is that an IP address is just an IP address, Trend Micro don't have any magic powers that tell them if an IP address is static or dynamic.

The fix may be as simple as rebooting the router so that you have a different dynamic IP address and then try again!

*You may notice that I'm far from enamoured by TrendMicro!

[MrFizz]

I'll try rebooting the router, thanks.

[MrFizz]

As you might imagine, I'm not enamoured by Trend Micro either! 😁

Who is using Trend Micro? 

If it is your colleagues in France there should be away for them to "white list" your email address.

see link

Safelisting procedures for external domains/email addresses - Hosted Email Security (trendmicro.com)

If it is a business that your colleagues email addresses are with they may have to contact their systems administrator to have your email address white listed.

No, that's not how it works. There are lots of blacklists that will blacklist ALL ISP dynamic IP addresses. This is to prevent (in the "olden days") trojan/virus controlled computers sending spam emails directly from their computer rather than using the ISP mail smart host (in this case mail.btinternet.com).

Of course it's legal, any blocklist can block whatever they want, and if people wish to use that blocklist then that's up to them.

If you have Gmail, send to one of your colleagues using that.
