Keeping up with new spam domains is a low-intensity task that many self-hosters probably get frustrated with. Let’s help each other by sharing spam domains as they appear.
I have set up monitoring that collects all domains with a counter for each one, making it easy to spot new spam domains as they appear.
I’ll try to keep the list below updated - it will be a best effort thing though.
Here’s my current spam domain list:
cellcom.quiktxt.com
email.uscc.net
fido.ca
messaging.sprintpcs.com
mobile.celloneusa.com
msg.telus.com
myairmail.com
mymetropcs.com
pcs.rogers.com
sms.ntwls.net
sms.wirefree.informe.ca
tmomail.net
tms.suncom.com
txt.att.net
txt.bell.ca
txt.bellmobility.ca
vtext.com
Feel free to add new domains in the comments - sharing is caring.
