"Failure sending mail" error with System.Net.Mail

S

Hi all,

I'm using System.Net.Mail (Framework 2.0) to send emails on scheduled
basis. This works great on Windows 2000 server. Rently we have
upgraded our servers to Windows 2003. Since then some of the emails
are failing from being sent to people. Ratio is like 1 in 30 are being
failing, I thought it is the mail size issue and I have unchecked the
mail size limit on SMTP server. Still I couldn't figure out why few
are not going out.

Any help is appreciated.

Thanks in advance.

Shil,

What is your idea how we can help you?
We know now that it fails sometimes on server 2003 while you think it did
not on 2002 (or have you a way to proof the latter?)

Proof... yes. We do log the actions on each email that goes out. On
Windows 2000 server they never failed. Now when we have transferred
the same code (VB.NET 2.0) to the Windows 2003 server, couple of the
emails are failing to go out.
