[mailop] Help with identifying invalid email domains

[Omid Majdi via mailop]

Hey all,

I'm looking to see if anyone has compiled any lists of invalid email domains? 
Examples of such would be typo domains and/or domains that accept all 
local-part addresses such as gmai.com, gmail.co, googlemai.com, or proton.com. 
If there's any resources someone could share for known invalid domains that 
would be incredibly helpful.

Thanks,

[mailop] Anyone from Spectrum / Charter.net on list?

Looking for anyone on list (or a contact) for Charter.net. We're experiencing 
some intermittent deliverability issues, potentially related to a limit of 
concurrent connections placed on us.

Thanks!

[mailop] Anyone from Centurylink.net (or related) on list?

[Omid Majdi via mailop]

Hey there,

We've been receiving some rejected messages from Centurylink.net along with a 
few other domains with the exact same rejection message which seems to suggest 
they are all related:

centurylink.net
tds.net
cableone.net
wowway.com
embarqmail.com

I couldn't find any postmaster addresses publicly available, but reached out to 
some abuse addresses I was able to find, but haven't had any response. Any help 
would be much appreciated.

[mailop] Anyone from Zoho on list?

[Omid Majdi via mailop]

Apologies for the additional noise, but also looking for anyone on list (or a 
contact) for Zoho. We're experiencing some deliverability issues, potentially 
related to a block list that we believe we are now removed from.

Thanks!
