|
<h3>MSGMail</h3>
|
|
<ul>
|
|
The MSGMail device is used to send mail messages to a recipient by connecting
|
|
to a SMTP server. Currently MSGMail supports only servers, that allow SSL secured connections
|
|
like Googlemail, GMX, Yahoo or 1und1.
|
|
MSGMail requires the perl pacakge <b>MAIL::Lite</b>.
|
|
For SSL support, Net::SMTP version 3.06 is required. On systems with an older version of Net::SMTP,
|
|
MSGMail requires the package <b>Net::SMTP::SSL</b>.
|
|
<br><br>
|
|
|
|
<a name="MSGMailDefine"></a>
|
|
<b>Define</b>
|
|
<ul><br>
|
|
<code>define <name> MSGMail <from> <to> <smtphost> <authfile></code><br><br>
|
|
Specifies the MSGMail device. At definition the message counter is set to 0.
|
|
From, To, SMTPHost and the authfile (see attributes below) need to be defined
|
|
at definition time.
|
|
</ul>
|
|
<br>
|
|
Examples:
|
|
<ul>
|
|
<code>define myMail MSGMail from@address.com to@address.com smtp.provider.host /etc/msgauthfile</code>
|
|
</ul><br>
|
|
|
|
<a name="MSGMailSet"></a>
|
|
<b>Set</b><br>
|
|
<ul><code>set <name> add|clear|list|send [text]</code><br>
|
|
Set is used to manipulate the message buffer of the device. The message
|
|
buffer is an array of lines of data, stored serial based on the incoming
|
|
time into the buffer. Lines of data inside the buffer could not be deleted
|
|
anymore, except of flashing the whole buffer.<br>
|
|
<ul><b>add</b><br> to add lines of data to the message buffer. All data behind
|
|
"add" will be interpreted as text message. To add a carriage return to the data,
|
|
please use the CR attribute.
|
|
</ul>
|
|
<ul><b>clear</b><br> to flush the message buffer and set the line counter to 0.
|
|
All the lines of data are deleted and the buffer is flushed.</ul>
|
|
<ul><b>list</b><br> to list the message buffer.<br></ul>
|
|
<ul><b>send</b><br> to send the message buffer.<br></ul>
|
|
<br>
|
|
Examples:
|
|
<ul>
|
|
<code>set myMail add Dies ist Textzeile 1</code><br>
|
|
<code>set myMail add Dies ist Textzeile 2</code><br>
|
|
<code>set myMail clear</code><br><br>
|
|
Full working example to send two lines of data to a recipent:<br>
|
|
<code>define myMail MSGMail donald.duck@entenhausen.com dagobert.duck@duck-banking.com smtp.entenhausen.net /etc/fhem/msgmailauth</code><br>
|
|
<code>attr myMail smtpport 9999</code><br>
|
|
<code>attr myMail subject i need more money</code><br>
|
|
<code>attr myMail CR 0</code><br>
|
|
<code>set myMail add Please send me </code><br>
|
|
<code>set myMail add 1.000.000 Taler</code><br>
|
|
<code>set myMail send</code><br>
|
|
<code>set myMail clear</code><br>
|

</ul><br>
|
|
</ul>

|
<b>Attributes</b>
|
|
<ul>
|
|
Almost all of these attributes are not optional, most of them could set at definition.<br>
|
|
<li><a href="MSGMailFrom">from</a><br>
|
|
sets the mail address of the sender</li>
|
|
<li><a href="MSGMailTo">to</a><br>
