If email is not being sent correctly please review the "Email Settings" (available from the software's Settings or Options). Most problems relate to email settings not being configured properly. Usually it is because the ISP SMTP server has not been entered.
The MAPI option is only available with some Windows based programs.
When the MAPI option is selected, email is sent using your default email program. The emails will be available in the history of the client (ie in the Sent box)
You must have MAPI-compliant email software installed. Eudora, Mozilla Thunderbird and Outlook(*) are MAPI compliant. If you do not have MAPI software installed, simply download and install the free version of Eudora from www.tucows.com, or Thunderbird (also free) from www.mozillamessaging.com/en-US/thunderbird/. You have to setup your email software as the default MAPI server. In Eudora use Tools / Options / MAPI / Always. In Outlook use Tools / Options / Make Default. In Mozilla Thunderbird go to Tools, Options and tick 'Use Thunderbird as the default mail application' in the General tab.
Outlook Problems: Some versions of Outlook cause problems because the automated send feature is disabled or it prompts you every time it needs to send a message (which defeats the purpose of automated email!). The easiest solution to this problem is to simply download the free version of Eudora from tucows.com. You will still be able to use Outlook as your main email application but you can setup Eudora simply for sending automated mail.
Thunderbird: similarly you will need to allow the sending of email by other application. The first time an email is sent you will be prompted if this is to be allowed. You should tick the checkbox to allow this always.
This is the process where the email is sent using a SMTP server. The SMTP server usually is provided by your ISP. Its role is to relay emails for you.
The most common reasons for SMTP to fail are:
When this option is selected the software sends the email directly to the remote person's email address. No outgoing server relays the email.
Possible problems with this option include:
