Error: Connection Failed While Sending
Posted by Laura Schindler, Last modified by Jen Ferraz on 30 March 2011 10:20 AM

The error message changes from client to client, but the common thread is that you receive an error about not being able to send, connection failed while sending, the connection to the remote server could not be established, or similiar text.

When this type of message occurs, there is a very good chance that your own internet service provider (ISP) is blocking your connection to us for sending email. ISPs known to do this on a wide-scale are Earthlink, SBCGlobal, Cox, and regional AOL dial-up as well as many smaller ISPs.

Email clients use a protocol known as SMTP to send messages to email servers such as ours. Some ISPs block SMTP conenctions from leaving their networks as a way of forcing you to use their own mail servers exclusively. The reason for doing that is most often to prevent their customers from sending junk email. If your internet provider is doing that, please email saas@mivamerchant.com


For technical users who would like to verify that their ISP is blocking outbound mail sending, here is how you do it:

On linux or other unix-like operating systems, just type the following at a command prompt:

telnet mivamerchant.net 25

For windows users, open a command prompt and type just "telnet" followed by the enter key. Next, type "open mivamerchant.net 25" followed by the enter key.

At this point you should see something similar to the following:

Connected to mivamerchant.net.
Escape character is '^]'.
220 mail.mivamerchant.net ESMTP

If you instead see it just sit there, or get a connection error, it is most likely your ISP blocking the connection.

This error can also occur if your antivirus or personal firewall software is blocking outbound connections. Please check your settings.

If your ISP is blocking port 25, our servers also support the alternate port 587 for sending.  This change will need to be made in the Advanced settings of your email client software.  Please contact support if you need assistance with this.
