Domain not able to send to my comcast.net address

Richard,  I have the same problem sending to comcast.net addresses.  Ionos is my server and I use Outlook MS 365 (not 2024).  My husband uses Comcast email.  He contacted a support rep and was told it is not a Comcast problem.  A ticket was opened.  We're in [Edited: Personal Information].  This started just after the most recent hurricane.  Can you help?  [Edited: Personal Information]

Running into the same issue sending to comcast.net email addresses -- I also have Ionos as my domain provider, but am sending via Gmail (using Ionos SMTP servers for authentication).  For me, the problem appears to have started last week around 10/15.

We would be more than happy to look into this for you @user_uwqzkc

Thank you for reaching out to us @bbunch67! Are you seeing an error message or error code when trying to send emails to Comcast email addresses using your Gmail with IONOS as your domain provider?

No error code has been included with the Comcast emails being returned (would have been helpful). However, as of yesterday the emails are now going through.
