Avoiding local maildrop when using CDOSYS

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
