Save and close all windows. Try again. If the problem continues then the problem is that your Internet Service Provider is blocking port 25 on the outgoing mail server. ISPs do this to prevent spam on their network. When this happens you will need to use the mail server that they provide you instead of your own. The mail server is generally smtp.yourISPname.com, however, it could be different so please contact your ISP to get the details. If you do not want to use your ISPs server for SMTP, and the ISP is blocking port 25, you can switch the port to 587 for your outgoing mail and use mail.yourdomain.com for the SMTP server name.

SEARCH Knowledgebase: Email Issues Email won't send. I get Outlook error 0X800CCC0E (port https://www.virtbiz.com/support/index.php?/Knowledgebase/Article/View/12/8/email-wont-send--i-get-outlook-error-0x800ccc0e-port-25-is-blocked 25 is blocked) Posted by VIRTBIZ Support - AC on January 11 2007 10:50 PM Many corporations and Internet Service Providers https://www.rackaid.com/blog/cannot-send-email-how-to-fix-email-sending-and-receiving-errors/ have decided to limit their users' use of outgoing e-mail. The reasoning for this action is that if they control each outlook cannot outgoing e-mail message, they can cut down on the amount of SPAM that originates from their network. Even though you are not a spammer, you must adhere to their rules. PLEASE NOTE: The inability for you to send email from another outlook cannot connect ISP is not under our control, and does not indicate a problem with the service that we provide. We provide Submission Port service to customers unable to send email using Port 25. You can configure your Outgoing Server (SMTP) to use port 587 instead. If this still does not work for you, you may be able to contact your company's Network Administrator or ISP and have them open up email relay to your server. In severe cases, you will be forced to use your service provider's email server for SMTP. You will need to contact your service provider for further assistance.

Frustrating, I know. In fact, fixing email delivery issues is one of the top three things we do for our server management customers. You can save yourself some money by checking these five items first. 1. Bad Passwords Never ASSUME, because when you ASSUME, you make an ASS of U and ME. -- Jerry Belson This sounds simple enough but many support tickets we see turn out to be simple password issues. People complain they cannot send email and assure us the password is correct. We reset the password and bang -- email is flowing again. I think the problem often stems from extra spaces. Firefox and other applications often add a spaces to copy and pasted passwords. To be certain you are not picking up a space, paste the password to your address or search box in your web browser. This is a quick and easy way to verify you've copied the password correctly. If ever in doubt, just reset your password when testing. Wrong Authentication Method Password authentication security and network security are different settings. They both must be correct.If your password fails after resetting, make sure you are using a valid authentication method. Most email clients support a variety of authentication methods such as:
Normal or Plain Password Encrypted Password Kerberos Most systems support normal/plain as well as encrypted passwords. In most cases, you should see an error about "authentication methods" if this is the problem. Password encryption and network security (Tip #5) are often confused. In many cases if you are required to use a secure network connection, you want to use a normal or plain password settings. This is not insecure because by using SSL at the network level, then entire transaction is secure. 2. Mail Server (SMTP) is Offline Sometimes mail servers crash -- not often but I see it happen on WHM/cPanel and Plesk servers. Simply restarting the service from the control panel often fixes the issue. Your email client should return a connection error. Thunderbird error due to an incorrect hostname. The clue in this message is "mail2.rackaid.com is unknown." In this case, there's a typo in the hostname. Watch carefully for such errors as they are common. If you are certain your hostname is correct, then check for DNS issues. 3. ISP Blocking Port 25 Your ISP is blocking port 25. This is a common issue on customer support desks. Many ISPs force you to use their own SMTP servers even if you have your own. U-verse, ATT DSL, and Comcast often block port 25 by default. I even see this on business accounts. You can test if port 25 is blocked by using a telnet client to connect to
