The Mail.Fields collection contains all message body fields. The
collection can be used to determine the value of a specific field item, or to
iterate through the collection and retrieve a list of all items in the message
body. See the Collection Object
for standard collection properties and methods.
Item = Mail.Fields(key|index)
Returns a variant.
The field collection is filled only on incoming message processing, that is, eventually
during the Mailing_OnAcceptMail event if the whole
message is available, or during the Mailing_OnReceiveMail
event.
A body field is composed of a field name, followed by the : or = char,
eventually followed by a field value. The body field name is composed of any
alphanumeric char, plus the _ . - chars. It can also contains
white spaces between other chars. The field value is composed of chars remaining
until the end of line or a quoted value (using double quote as quoting char).
