Email send by groups.io are bounced


 

To whom it concerns,

I received a mail that my MTA (mailserver) is bouncing emails send by MTA's from groups.io
It looks like that at least 1 MTA is on the blacklist

Below a small excerpt of what is send to the MTA of groups.io

And an excerpt from my MTA logfile:

RDNS of the IP-address show? that it is the web01.groups.io

So if somebody is missing mails, this is probably the cause.

Yes, we have been having trouble with Spamcop and Spamhaus for some time now. The creator of groups.io has been working with both to get them to get us off the list of blocked servers, but this has not been straightforward and is still an ongoing effort.
