We have recently begun experiencing a problem sending messages via cfmail.
We're not sure
exactly when this started occurring. Our users just brought it to our
attention, but the
ColdFusion logs indicate this problem has been going on for a few weeks.
We have several ColdFusion 7 applications on our intranet that, among other
things, generate notifications
to our users via the cfmail tag. Some of our applications, all in-house
developed, have been running
successfully for years. And all applications exhibit this aberrant behavior.
For some as yet unexplained reason, ColdFusion has started randomly and
intermittently
generating multiple email messages to users. Sometimes a user will correctly
receive a
single message, sometimes multiple. Multiple, meaning 2 or 3. There is no
looping involved when creating
the message, no attachments, and the message is always addressed to a single
recipient.
I don't believe it to be a CF scripting problem. As I was watching what was
happening
on the server I was capturing a copy of the mail spool file before ColdFusion
grabbed it and compared that with what was reported in the mailsent.log file.
Sure enough, sometimes a single spool file would result in
multiple messages, and sometimes only a single message--to the exact same
person. But this doesn't
happen to everyone.
I don't see anything wrong with the contents of the spool file. A spool file
that generates a single
message looks exactly the same as one that results on multiple messages--to
the same user--and it appears to happen randomly.
I can't be the only one in the world to experience this.
