My new format webmail is full of spam email. All of this spam was filtered out in the old version, but now my inbox is full of junk. Will this be addressed or updated or will I have to pick through all the junk in order to find legit mail?
Check your settings in webmail. Make sure that "Enable spam filtering" and "Save a copy of emails marked as spam" are both selected. See https://www.xfinity.com/support/articles/spam-filters-and-email-blocking-new-experience.
