Undeliverable Mail \ Unknown Exception

Report · Dec 04, 2009

I am seeking assistance in identifying the cause of an issue that results in undeliverable email when using cfmail. On occasion (4 to 12 times in a 24 hour period) an email will be determined to be undeliverable and will be transferred to the /Undelivr directory. Entries exist in the exception.log, however they are of no help in identifying the issue. The first three lines of the entry appear as follows:

"Error","scheduler-6","12/03/09","06:04:44",,""
javax.mail.MessagingException:
at com.sun.mail.smtp.SMTPTransport.issueCommand(SMTPTransport.java:879)

Note that there is no detail message in the “javax.mailMessagingException:” line.

A corresponding message is written to the mailsent.log. It appears as follows:

"12/03/09","06:04:44",,"Moved undelivered mail: Mail19743.cfmail to /usr/apps/coldfusionmx/Mail/Undelivr directory" "Information","scheduler-6"

Finally, the message in the mail.log file appears as:

"Error","scheduler-6","12/03/09","06:04:44",,""

The email messages that are deemed to be undeliverable are successfully delivered when they are re-spooled for delivery.

In an effort to determine if the problem is associated with the SMTP server, the environment was configured to use a different server. The same problem occurred using both SMPT servers.

A summary of the environment is:

CF MX 6.1 (Java 1.4.2_11) running on Solaris 9

Thank you in advance for your assistance.

We have similar issues and did the following things to deal with it.

Set up a scheduled job that moves files from the undeliverable folder back to the spool once. If it gets sent the next time around, we are happy. There is also an email notification to people who care, and a web page that enables us to read and eventually delete the unsent message.

The messages that don't get sent the 2nd time around pretty well always have something wrong with them, such as a "from" value that is not a valid email address.
