Hi guys,

I hope this would be the right community. My MX is listed on a blocklist which is normaly down.
This old acticle, points this out

But today morning nobody could send an email to our company, Error 550 domain is blocklistet on

So if the blocklist is down, noboby could manage it.Thats my problem.

Similar to, there a lot of helpfully answers like " keep calm or dont care about", well my boss keeps an other opinion.

Hope anybody has an hint.
