RE: E-mail- Batch is SLOW

Paul,

I had to write an email throttle to do the opposite of what I am about to
recommend to you, because many ISP's flag as spam a sender when too many
emails are received too quickly.

If that is not a problem for you, you may want to verify that your sending
computer has reverse-lookup email authentication configured  (PTR record).

Optionally you may want to send through a relay such as PostCast, or IIS and
allow those to handle delivery. I've used both of these. Sending to them is
like printing to a spooler. Both have email logs that help fix other email
sending problems (blocked, bad ehelo, helo, bad PTR, etc.)

Subject: E-mail- Batch is SLOW

I posted a question about this 1-2 months ago and thanks for the feedback  
then. I have further isolated the problem.
 
I am using 4D Runtime 2003.6.  When my clients send group e-mails  
(100-500) short e-mails (less than 500 characters), it can take hours when
they  are
using authentication. When the few that don't have to use authentication  
(they can do it either with or without), it take about 15 minutes.
 
So here is the scenario:
 
One of my customer sends 100 e-mails ( 500 characters) with authentication:
 takes 2-3 hours.
Same customer sends 100 e-mails(500 characters) without authentication:  
takes 10 minutes.
Same customer send 100 e-mails(500 characters) with authentication from  
OUTLOOK: takes 10 minutes.
 
Below is my code that I loop when authentication is required. Am I missing  
something? I have also tried just using the authentication on the first
e-mail  and not the subsequent ones but get an error message on the
subsequent  
ones.
 
  If  (vEmailResponseTimeOut<5)
$Error:=IT_SetTimeOut  (15)
Else
$Error:=IT_SetTimeOut  (vEmailResponseTimeOut)
End if  

Case of
:  (Not(ErrorCheckingMail ("New";SMTP_New ($smtp_ID))))
:  (Not(ErrorCheckingMail ("Set Port";IT_SetPort  (2;vEmailPort))))
: (Not(ErrorCheckingMail  ("Auth";SMTP_Auth  
($smtp_ID;vEmailUserName;vEmailUserPassword;0))))
:  (Not(ErrorCheckingMail ("Host";SMTP_Host  ($smtp_ID;vEmailSMTP;0))))
: (Not(ErrorCheckingMail  ("To";SMTP_From ($smtp_ID;vEmailFromDefault;1))))
:  (Not(ErrorCheckingMail ("New";SMTP_To  ($smtp_ID;$1->;1))))
: (Not(ErrorCheckingMail  ("Body";SMTP_Body ($smtp_ID;vEmailText;1))))
:  (Not(ErrorCheckingMail ("Subject";SMTP_Subject  
($smtp_ID;vEmailSubject;1))))
: (Not(Attachments  ($smtp_ID)))
: (Not(ErrorCheckingMail ("Send";SMTP_Send  ($smtp_ID))))
: (Not(ErrorCheckingMail ("Clear";SMTP_Clear  ($smtp_ID))))

End case
 
Thanks for any help.
