I experienced strange problems with some ASP scripts at a clients hosted web server. The script sends e-mails after completed execution and occasionally (quite often) some of the e-mails are not delivered or are delivered much later than expected. When running in a hosted environment it is also very hard to track as you have very limited access to the server itself. After digging in some Microsoft documentation I noticed that it is possible to direct the traffic to the SMTP server of your choice instead. CDOSYS will execute a little bit slower but now I have the opportunity to target the e-mail to the SMTP server of my choice.

    Set oCdoMail = Server.CreateObject(“CDO.Message”)

    Set oCdoConf = Server.CreateObject(“CDO.Configuration”)

    sConfURL = “http://schemas.microsoft.com/cdo/configuration/”

    with oCdoConf

      .Fields.Item(sConfURL & “sendusing”) = 2

      .Fields.Item(sConfURL & “smtpserver”) = “smtp.themailserverofyourchoice.com”

      .Fields.Item(sConfURL & “smtpserverport”) = 25

      .Fields.Item(sConfURL & “smtpauthenticate”) = 1 

      .Fields.Item(sConfURL & “sendusername”) = “accountname@themailserverofyourchoice.com“ 

      .Fields.Item(sConfURL & “sendpassword”) = “verysecretpassword” 

      .Fields.Update

    end with

 oCdoMail.From = ”fromemail@someserver.com”

 oCdoMail.To = ”toemail@someserver.com”

 oCdoMail.Subject = ”Subjct of the message”

 oCdoMail.HTMLBody = “Some message including some HTML coding”

 oCdoMail.Configuration = oCdoConf

 oCdoMail.Send

 Set oCdoConf = Nothing

 Set oCdoMail = Nothing
