NOTE: Text Messaging to Cell Phones via SMTP(email) is no longer recommended. Cell carriers filter 'email-to-text' messages, and in many cases messages are delayed (from 10 minutes and up to 48 hours) or discarded as SPAM or for violating the carrier policies. Please see information on the InfoRad Messaging Gateway for reliable cell phone text messaging. InfoRad Messaging Gateway Information

If you still desire to send text messages to cellular phones using email services (your carrier has whitelisted you or you have carrier Enterprise Messaging services utilizing Internet email), the link below will show you a couple different ways to do so. We recommend that you use your own outgoing email server as a Messaging Service. Click the following link to set up Pagers and Cell Phones via the Internet.
If you do not know your Internet Service Provider (ISP) and if you use Outlook or other email client to send out email, then try our Interactive HowTo's and follow the one for Outlook 2000.

This is a popular error among InfoRad users who are sending text messages to cell phones via Internet email. Continue Reading If you are sending text messages via Internet SMTP or email. Otherwise, Refer to SNPP Below.

• The most common occurrence is InfoRad users that are connecting directly to cellular company email servers (Ie. Verizon's smtpsp.vtext.com). Therefore, we recommend that you either setup the InfoRad software to use your own outgoing email (SMTP) server or use some other 3rd party, commercial email server that you can depend on (Like maybe Google's Secure SMTP Server).
  
  
• Another common occurrence is caused by an Internet Service Provider or network that does not allow you to connect to email servers outside of their own domain. We recommend that you first try using the email server provided by your Internet Service Provider. Click Here to view InfoRad's list of ISPs. If you use Outlook, then you may find this information in Outlook normally under Tools, Services (Outlook 2000) or Tools, Email Accounts (Newer). You would need to know your outgoing email (SMTP) server address and whether or not it requires authentication. Once you have that information, for any Receiver that uses an email address for the Receiver's ID, you can enter a New Messaging Service using the email server information you obtained from above (ShowMe).
  
  
• Some Cases show that the connection to the email server is being blocked by some firewall or antivirus software. If you are familiar with configuring your antivirus or firewall software, then add an exception for the InfoRad software (normally, Winpage.exe is the executable and port 25 for SMTP). An alternative is to try disabling the antivirus software from scanning outgoing email. However, you may want to keep it scanning your incoming email. Sometimes, there is a website url sjbl.org in the response coming back from the hardware (in the error message itself) that provides you with a link to which you can browse and have yourself removed from the Spam blocking list. If this is the case, then we would caution you to investigate this issue further before you find yourself on this list again and not be able to have yourself removed from it. Check with your local Internet Service Provider and/or antivirus software to find out what their rules are concerning Spam. You may have to follow these rules to prevent yourself from ending up on such a list.
  
  
• Sometimes an email server will tell you that the email address you entered is incorrect. For instance, setup a Receiver to send to XXX5551212@vtext.com and select Verizon PCS – Internet SMTP for the Service (make sure that you also have your own email address entered under Setup, Internet Settings, ReplyTo Address). Send a test text message and you’ll get error 6203 indicating that XXX5551212@vtext.com is not a valid Verizon (vtext) email address. To fix, correct the email address and try again.
  
  
• One instance can be caused by not having a ReplyTo Email Address entered under Setup, Internet Settings. (Show Me)
  
  
• Other cases have shown that an this error can occur when an email server (Messaging Service) requires authentication but either the InfoRad Wireless software does not have SMTP Authentication enabled or an incorrect username and password is entered (under Edit, Messaging Services for version 9.7.X and higher. Version 9.6.X does not support SMTP Authentication. You will need to upgrade your software. Call (800) 228-8998 for upgrade options).
  
  
• 7/17/07 - A Customer was receiving error 6203 when using own exchange server as a Messaging Service to send to cell phone emails. The Response from the email server showed WSAEWOULDBLOCK, which is a Windows Sockets Error 10035 according to Microsoft ( Refer to http://msdn2.microsoft.com/en-us/library/ms740668.aspx ). To fix, the customer changed from using the loopback address (127.0.0.1) to the network IP of the exchange server.
  
  
• 11/27/07 - Make sure you check that the Messaging Service is setup correctly. This is what happened when I had the wrong SMTP Server Address entered for the Messaging Service (it should have been mx1.business.mindspring.com instead of mx.business.mindspring.com). The Receiver ID, of course, is techsupport@inforad.com. I received error 6203 and the Response from hardware (in the error message) showed the following:
  
  VerifySmtpConnection: Checking connectivity to SMTP server mx.business.mindspring.com:25 smtp_host: mx.business.mindspring.com smtp_port: 25 WaitForData timed out. Failed to get initial response. The SMTP server may be denying access for this domain.
  
  Another clue indicating that you may have the Messaging Service setup incorrectly can be found in the Response from hardware (in the error message). It is similar to the following:
  
  SendEmail: SMTP_Connect: Connecting to SMTP server mail.earthlink.net:25 smtp_host: mail.earthlink.net smtp_port: 25 smtp_user: NULL trying_auth_method: NONE InitialResponse: 220-pop-cowbird.atl.sa.earthlink.net ESMTP Exim 3.36 #1 Tue, 27 Nov 2007 08:58:54 -0500220-NO UCE. EarthLink does not authorize the use of its computers or network220 equipment to deliver, accept, transmit, or distribute unsolicited e-mail. login_method: NONE or already authenticated CONNECTED to ESMTP server mail.earthlink.net:25 subject: from: recipients: 550 Authentication required. Help at http://www.earthlink.net/go/emailsettings Failed when sending RCPT TO: bad_address: XXX5551212@email.com Send failed.
  
  Therefore, to fix you would go under Edit, Messaging Services, and edit the Messaging Service being used for that Receiver(s). Check the box for "My server requires authtentication" and enter a valid email address and password.

If you're sending via the Internet SNPP (supported by Nextel or Alltel phones and numerous paging companies - ShowMe), then it could be that you have an incorrect Receiver ID entered. Make sure that you are using the ten-digit phone number of the pager or cell phone. Do not use dashes, spaces, or parentheses. When this error happens, the explanation text sent by the SNPP server will be included on the error screen along with this error message. That explanation should provide more detail on why the transaction failed. The explanation might be, for example, "550 Error, pager ID must be 10 digits" or "550 Error, pager ID cannot be identified" and so on.

• Click Edit, Receivers and make sure you have the correct seven or ten-digit phone number entered. Do not use dashes, spaces, or parentheses.
