I followed these directions and upgraded to the 4.20 beta... everything is fine now.

If you have email problems when using MAPI:
Do you have MAPI compliant email software installed? Eudora, Netscape Mail, Lotus Notes and Outlook(*) are MAPI compliant. If you do not have MAPI software installed, simply download and install the free version of Eudora from tucows.com.
Have you setup your email software as the default MAPI server? In Eudora use Tools / Advanced / MAPI / Always. In Outlook use Tools / Options / Make Default.
Are you running as a service under Windows NT/2000/XP? If so, you must change the "Log On As" password for the IVM Service to be able to send email. To do this, after you have set Run as Service, open Control Panel / Administrative Tools / Services. Double click on "IVM Service", select the Log On tab, select this account and then enter the name and password of the user account IVM must use to send email.
Outlook Problems: 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.
If you have any of the above problems you should consider using the IVM Internal Simple SMTP. To do this, click on the Email Settings button next to email on the Mailbox Properties box. Select Internal Simple SMTP and enter your ISP's mailhost server and your email address.
If you have email problems when using Internal Simple SMTP:
Have you entered your ISP SMTP mailhost server using the Email Settings button on Mailbox Properties?
If you receive an error message when attempting to send mail with SMTP your server may require authentication (ie. username and password) to send email. Use the format smtp.yourmailhost.com:username:password for the mailhost.
