Troubleshooting "send/receive e-mail" errors in e-mail clients






Troubleshooting "send/receive e-mail" errors in e-mail clients
If you cannot send/receive e-mails using your e-mail client (Outlook, Eudora, Netscape mail etc) please check the following:

  • Check to make sure all the settings in your account are correct.
    Incoming Server: mail.vintob.com
    Outgoing Server: mail.vintob.com
    User name/ Account name: (YourEmail@DomainName.com)
    Password: e-mail password (passwords are case-sensitive)


  • You can receive but not send messages then please check the following:

    • Please check to see if outgoing server is authenticated. To send e-mails you have to authenticate (using user name and password) the outgoing SMTP server (mail.vintob.com)

    • Your ISP may be blocking port number 25. (Port 25 is the default port for outgoing server). You can perform a small check to find out if port 25 is blocked or not: (These instructions are for the Windows OS only)
      • Open your DOS prompt by clicking Start -> Run -> Type in command and click OK
      • In the window that pops up type in telnet mail.vintob.com 25 and press Enter
      • If your ISP is not blocking port 25 then the following message is displayed. If port 25 is blocked then the connection just times out
      • Now try the same check with your ISP's outgoing server. For e.g. telnet mail.vintob.com 25. If this works then port 25 is blocked
      • Try using port 587 for outgoing server. You can use your ISP's outgoing server

    • Check to see if "virus-checking of outgoing mail" option is turned off. For example in Norton Antivirus you can turn it off as follows:
      • Run Norton Antivirus. Make sure you are logged in with Administrator privileges
      • Click Options button. Select E-mail on the left navigation menu
      • Uncheck Scan Outgoing E-mail (recommended) and click OK
      • If you are using AOL, regardless of the SMTP server you configure your e-mail client to use, AOL forces your outgoing mail to use AOL SMTP server. AOL outgoing server does not currently support authenticated SMTP. Please use the outgoing mail settings provided by AOL

    • If you are behind a firewall, try turning it off and testing

    • Outlook Express for Macintosh does not have the option for authenticating outgoing mail servers. Use your ISP's outgoing server or change the e-mail client

    • Make sure you have Unchecked the box near Log on using Secure Password Authentication (SPA)


  • If you have problem receiving e-mails then try the following:
    • Open your DOS prompt by clicking Start -> Run -> Type in command and click OK
    • In the window that pops up type in telnet mail.vintob.com 110 and press Enter.
      Then type user yourname@vintob.com and press Enter. Type pass email_password and press Enter. You will see a message that says how many messages you have.

    If this works, it means you have a problem with your e-mail client.


  • Mail problems are also caused by applications or software such as Zone Alarm running on your system. To check this, please click Start -> Run -> type msconfig and press Enter. Click Startup tab and check for a reference to zonalarm or other similar applications. Also, check the firewall settings to see if the port 25 and 110 are open
