expected cname for to match sendgrid.net
Hi!
In your do admin panel go to Network > Domains > yourdomain.com
Then, create the following cnames:
Source Target
mail u2210027.wl.sendgrid.net.
s1.domainkey s1.domainkey.u2210027.wl.sendgrid.net.
s2.domainkey s2.domainkey.u2210027.wl.sendgrid.net
Notice two things:
In the source don’t put the whole domain aka mail.yourdomain.com; just the subdomain aka mail
In the target append a dot
