22    '''the send mail tag, used like thus:
23
24    <dtml-sendmail mailhost="someMailHostID">
25    to: person@their.machine.com
26    from: me@mymachine.net
27    subject: just called to say...
28
29    boy howdy!
30    </dtml-sendmail>
31
32    Text between the sendmail and /sendmail tags is processed
33    by the MailHost machinery and delivered.  There must be at least
34    one blank line seperating the headers (to/from/etc..) from the body
35    of the message.
36
37    Instead of specifying a MailHost, an smtphost may be specified
38    ala 'smtphost="mail.mycompany.com" port=25' (port defaults to 25
39    automatically).  Other parameters are
40
41    * mailto -- person (or comma-seperated list of persons) to send the
42    mail to.  If not specified, there **must** be a to: header in the
43    message.
44
45    * mailfrom -- person sending the mail (basically who the recipient can
46    reply to).  If not specified, there **must** be a from: header in the
47    message.
48
49    * subject -- optional subject.  If not specified, there **must** be a
50    subject: header in the message.
51
52    * encode -- optional encoding. Possible values are: 'base64',
53     'quoted-printable' and 'uuencode'.
