SMTP Question

Hi,

How can I test our smtp server (used for applications)  to verify settings are ok.  Seems much of the emails sent are ending up in spam.  This is setup in IIS.

Thanks

Hi,

1. Test you mail server settings at

2. Check your mail content against spam filters - send test mail to dedicated address at http://www.isnotspam.com/ and view the results. IsNotSpam online spam checker was created to help you test email and newsletter content, and alert if it is likely to trigger spam filters.

Chances are the emails are the issue, not the configuration of the SMTP service.  As long as you are not configured as an open relay (only internal users/services can use the service), its more likely that one of the following issues exists:

1. Your external IP address for the SMTP service may have a bad reputation.
2. Your SMTP service IP may be blacklisted
3. You're emails are setting off SPAM filter alarms due to format, content, envelope info.
4. If you are using TLS/SSL when sending emails, your certificate may be the issue

As mentioned above, check out the mxtoolbox site.  Test you DNS, you SMTP Server, you IP for blacklistings.  Then post the results.
