History
ColdFusion MX 6.1: Added support for multipart mail mesages with Text and HTML parts. Changed the attachment name separator: the TAB character is now the separator between attachment names in the attachments and attachmentfiles query fields if a message has multiple attachments. This behavior is identical to ColdFusion 5 and earlier versions.
ColdFusion MX: Changed the attachment name separator: the comma separates names in the attachments and attachmentfiles query fields if a message has multiple attachments.
Usage
The cfpop tag retrieves one or more mail messages from a POP server and populates a ColdFusion query object with the resulting messages, one message per row. Alternatively, it deletes one or more messages from the POP server.
To optimize performance, two retrieve options are available. Message header information is typically short, and therefore quick to transfer. Message text and attachments can be very long, and therefore take longer to process.
cfpop query variables The following table describes the variables that provide information about the query that is returned by cfpop:
Variable names | Description
--- | ---
queryname.recordCount | Number of records returned by query
queryname.currentRow | Current row that cfoutput is processing
queryname.columnList | List of column names in query
queryname.UID | Unique identifier for the e-mail message file
Query message header and body columns The following table lists the message header and body columns that are returned if action = "getHeaderOnly" or "getAll":
Column name | getHeaderOnly returns | getAll returns
--- | --- | ---
queryname.date | yes | yes
queryname.from | yes | yes
queryname.messagenumber | yes | yes
queryname.replyto | yes | yes
queryname.subject | yes | yes
queryname.cc | yes | yes
queryname.to | yes | yes
queryname.body | not available | yes
queryname.textBody | not available | yes
queryname.HTMLBody | not available | yes
queryname.header | not available | yes
queryname.attachments | not available | yes
queryname.attachmentfiles | not available | yes
If the mail message includes a part with a Content-Type of text/plain, the queryname.textBody column contains the part's message content. If the mail message includes a part with a Content-Type of text/HTML, the queryname.HTMLBody column contains the part's message content. If no Content-Type matches these types, the columns are empty. The queryname.Body column always contains the first message body found. The queryname.attachments column contains a tab-separated list of all the attachment names. The queryname.attachments column contains a tab-separated list of the locations of the attachment files. Use the cffile tag to delete these temporary files when you have processed them. To create a ColdFusion date/time object from the date-time string that is extracted from a mail message in the queryname.date column, use the following table:
Locale | How to create a ColdFusion date/time object from queryname.date
--- | ---
English (US) | Use the ParseDateTime function. If you specify the pop-conversion attribute, the function adjusts the date/time object to UTC.
Other | Extract the date part of string; pass it to the LSParseDateTime function
Note: | To set the default display format of date, time, number, and currency values, use the SetLocale function.

    <h3>cfpop Example</h3>
    <p>cfpop lets you retrieve and manipulate mail in a POP3 mailbox.
    This view-only example shows how to create one feature of
    a mail client, to display the mail headers in a POP3 mailbox.
    <p>To execute this, un-comment this code and run with a mail-enabled CF Server.
