Sendmail sending blank emails.

[kumarlimbu]

Hi everyone,

We have setup sendmail on a linux box as our SMTP server. This server is responsible for sending emails to users whenever anyone register. These emails will be used for validation purposes.

What we have found during the course of time is that around 30% of new users do not validate their email, which we feel is quite high. We have also received complaints from users who say that they received blank messages on their validation email.

Whenever I am testing the app, I have never encountered any problem in creating an account and validating. Has anyone encountered similar issues with blank email being sent? Does anyone have any suggestions where we should look to begin troubleshooting this problem?

Thank you for your time.

intuitively i guess your web site and not sendmail causing the problem.
  i would turn debugging on for my test site and register n times
looking for the behavior.

intermittent problems are a pain.  good luck,
eric c.

I would agree here. One thing that would help is if you could have one
of your users send you back the email they received with the Internet
headers included. One well documented problem with Outlook is that a
digitally signed message using PGP/MIME will show up with an empty body
and 2 attachments (the body and the signature). While this specific
problem is not your case, it is possible that there could be an error
in the content-type or other header element where most email clients
handle.
