(MacAfee instructions below)

"... Now from David This might be too specific an issue, but I'll mention it anyway. Setting SmtpMail.SmtpServer using the server name gives:
Could not access 'CDO.Message' object.
innerexception: The transport failed to connect to the server.
Setting SmtpMail.SmtpServer using the IP address gives:
Could not access 'CDO.Message' object.
innerexception: The message could not be sent to the SMTP server. The transport
error code was 0x800ccc15. The server response was not available
I tracked this issue down to McAfee VirusScan Enterprise 8.0 VirusScan Console, Access Protection, Properties, Port-Blocking tab, Rule:"Prevent mass mailing worms from sending mail" This blocks outbound access to any port 25 on the network. Edit button shows a list of excluded processes to which new processes can be added. Regards, DavidG ... "
