For any incorrectly configured protocol, inbound mail may fail.

Common Causes of Comcast Email Not Receiving on Phone and Computer
-
H3: Full Mailbox or Storage Limit Reached

One of the most common reasons is a full inbox. When storage runs out, Comcast **automatically rejects all new emails**.

Fix:

* Empty spam, trash, and sent folders

* Delete large attachments

Incorrect Server Settings (IMAP/POP/SMTP) H3
Wrong server settings block incoming mail.
Correct settings:
| Type | Server           | Port | Security |

| ---- | ---------------- | ---- | -------- |

| IMAP | imap.comcast.net | 993  | SSL      |

| POP  | mail.comcast.net | 995  | SSL      |

| SMTP | smtp.comcast.net | 587  | TLS      |
H3: Spam Filters & Block Lists
Filters may block important senders unintentionally.

Fixes:

* Check spam folder

* Mark messages as “Not spam”

* Review block lists

* Reset filters

H3: Email Forwarding Errors

The forwarding rules can send emails to another account silently.

H3: Comcast Server Outages or Maintenance
