Comcast Email Issues
Comcast Email Issues
Well to start the new year off right, it would seem that Comcast/XFinity is rolling out some less-than well known or publicized updates for their Internet customers. Which of course is causing more than a few Comcast Email Issues. While the reasons for this change are many and understandable, the fact that it is not more openly communicated leaves most of us scratching our heads over the weekend. Especially with their customers.
Anyway, many ISPs (Internet Service Providers) such as Comcast have been blocking Port 25 for some time now. This isn’t new news to us. However, it would seem that Port 26 is now being blocked as well. This is what has caused the latest wave of Comcast Email Issues.
Some background to the Comcast Email Issues
For years, it has been well known that spammers use Port 25 to send out hundreds or even thousands of unwanted emails every day. They have even gone as far as creating malware, viruses, worms and so forth to forcefully take over your computer and your email to do their dirty deeds for them – mostly without the knowledge of many people!
To combat this, many ISPs have been blocking the use of Port 25 which allows for an unsecured connection to the ISP’s SMTP (i.e. out-going) email server. It would appear that Comcast is no longer supporting the use of Port 26 as a workaround for sending email through your domain-based email server using a third-party application such as Outlook or Thunderbird. We cannot confirm this as of yet, however the Comcast/XFinity website does clearly recommend the use of Port 587.
Port 587 forces the use of a SSL/TSL (i.e. secure) connection in order to send any email. That means if you are a Comcast customer, you must change your settings to use Port 587 and use your XFinity username and password in order to send email using Outlook, etc.
How to fix the Comcast Email Issues
Unfortunately, not all web hosting providers support the use of Port 587 for POP3 email accounts, so you have basically these choices:
- Use web-mail instead (if its supported)
- Switch to IMAP (if its supported)
- Switch to Gmail
- Fire Comcast and/or your current web hosting provider
- Resort to snail-mail
Fortunately however for our business web hosting customers, POP3 and IMAP are both supported as well as using Port 587 with authentication via your ISP.
