Hi all,
I've been trying the https://www.invaluement.com/spdata/sendgrid-id-dnsbl.txt list but lately, I've been getting 'Couldn't connect to server' errors, fairly regularly. The site says: 'can set them up for frequent downloads (every minute!) using CURL or WGET - only using the setting that only downloads when the server versions are newer.' I am doing that, once per minute... are others having this issue? thanks -- micah
