Retrieving Messages
You
have seen that ColdFusion can send email via the
cfmail tag. In addition to sending email,
ColdFusion can also retrieve email messages using the Post Office
Protocol (POP3) via the cfpop tag. Using this tag,
ColdFusion can retrieve message headers, message contents including
multi-part messages (this is new in ColdFusion MX 6.1), and file
attachments. In essence, this allows you to use ColdFusion to create
a web-based email system, like Yahoo! Mail or Hotmail. The
cfpop tag can also create applications such as
auto-responders and mailing-list managers.
Retrieving Message Headers
The
cfpop tag can retrieve just the header portion of
email messages stored on a POP server. This is useful when you want
to retrieve summary information such as the message title for more
than one message. Retrieving just the message headers allows you to
avoid the overhead associated with retrieving the entire contents of
each message you retrieve. In the context of a web-based email
client, this technique is used to build a list of messages in a
user’s mailbox. You can retrieve the headers for a
group of messages by setting the action attribute
of the cfpop tag to
GetHeaderOnly as shown in Example 13-8.
