• Can Receive But Not Send Email

    There are a great many reasons a user may not be able to send email but can receive it just fine.  This will focus on some of the more common issues mostly involving Outlook and Outlook Express. Below are some common questions you can ask yourself to assist in troubleshooting:

    1. Has the ISP\email provider recently changed?
    2. Has the email account info been changed recently?
    3. Any system changes that have taken place?

    To troubleshoot #1, first check if your internet is even working then contact your email provider, perhaps they are having email issues (make sure you can answer the questions #2 and #3 to assist in support). Sometimes your email provider may not be your ISP, if this is the case it is possible your ISP requires all SMTP traffic to authenticate and relay through them and not your actual email provider. This has been the case with quite a few ISP’s to restrict SMTP traffic due to worm activity.  You should be able to get this information from your ISP technical support (Rogers and Bell usually require relaying through their SMTP) .  To check your SMTP authentication read this.

    For #2, very simply have you changed anything such as your email address or password, or has your ISP.

    #3, has any new software been installed or updated.  Most importantly, has your antivirus or firewall been updated or changed and are they performing correctly.  Sadly anti virus and firewalls are the most common cause of stupid email problems. There are some good methods from Microsoft for advanced troubleshooting here.

    Below is a list of the numerous different errors and codes you may receive when you can receive but not send email.

    • No connection could be made because the target machine actively refused it.
    • sending reported error: [ERROR]. The server connection refused from [IP ADDRESS]
    • The server could not be found. (Account:account name, POPserver:’mail’, Error Number: 0x800ccc0d)
    • Task ‘server name – Sending and Receiving’ reported error (0x800ccc0f): ‘The connection to the server was interrupted. If this problem continues, contact the server administrator or Internet service provider (ISP). The server responded: ? K’
    • Your server has unexpectedly terminated the connection. Possible causes of this include server problems, network problems, or a long period of inactivity. Account. account name, Server: ‘server name‘, Protocol: POP3, Server Response: ‘+OK’, Port: 110, Secure(SSL): No, Error Number: 0x800ccc0f
    • Task ‘SMTP server name – Sending and Receiving’ reported error (0x80042109): ‘Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact the server administrator or Internet service provider (ISP).’
    • The operation timed out waiting for a response from the receiving (POP) server 0x8004210a
    • A time-out occurred while communicating with the server 0x800ccc19

    Other codes:
    * 0x800ccc15  * 0x80042108  * 0x800ccc0e  * 0x8004210b 
    * 0x800ccc0b  * 0x800ccc79 * 0x800ccc67  * 0x80040900 
    * 0x800ccc81

    Pre Outlook 2003 problem:

    (0x800ccc15) means SOCKET_CONNECT_ERROR -    Unable to open Windows Socket:

    This behavior can occur when connecting to an Internet mail server using a SOCKS proxy server, even though you can successfully connect to the Internet using the SOCKS proxy server.   This was fixed in Outlook 2003.   To fix, uninstall Outlook, change all the files which contain "mapixxx.xxx" to "mapixxx_old.xxx" and then reinstall Outlook.

    • I spent weeks trying to figure out what was happening. My internet was working fine, but not my e-mails. At the end of the day, it is NOT Norton, Outlook, your ISP, Windows Explorer, etc. It is simply your modem. Go and unplug it for a minuite, make sure your connections are tight, then plug it back in. That should fix the problem.

    • That is GREAT advice!
