    Mail Error

    Hi Guys,

    Need some help, when we have users subscribing to our mailing lists, they get an email with the below:

    Any ideas on how to fix this? 

     

    The mail server has encountered errors processing your request:

     

     * Unrecognized command "".

     * Unrecognized command "Message".

     * Unrecognized command "".

     * Unrecognized command "Click".

     * Unrecognized command "".

     

    Please correct and resubmit your request(s). If you need further assistance, either use the Mail Server HELP command, or else contact the postmaster or administrator of this system.

    Re: Mail Error

    I assume they want to subscribe via email?!

    In that case you have to ensure they send a new mail in plain text - no html! Mail should look like this:

    SUBSCRIBE <listname> [<fullname>]
    EXIT

    EXIT is to tell mailserver to ignore eventually following signature.

    If you want to supply a link via webpage, should look like that (no blanks in parameters and CRLF has to be added!!!)

    <a href="mailto:maiser@domain.de?subject=subscribe&body=subscribe%20testlist%0D%0Aexit%0D%0A>subscribe to list testlist</a>

    But the same problem ... plain text mail expected!

    Best choice so maiser gets a plain text mail is to have formulars by ...

    • enabling the webinterface of mercury or ...
    • creating a web contact formular by your own calling a script that sends a plain-text-mail to maiser (had that with option for subscribe and unsubscribe).

    In all solutions you should moderate that list so subscribers are not automatically subscribed!

    bye    Olaf

    Forgot one, because it doesn't work with Pegasus - nice simple html form without scripting (if you want to use it, ensure to save the HTML-file with encoding UTF-8 !!!):
    <!DOCTYPE html>
    <html>
        <head>
            <meta http-equiv="content-type" content="text/html; charset=UTF-8">
        </head>

        <body>
            <h2>Subscribe to mailinglist:</h2>
            <form action="mailto:maiser@domain.de?subject=subscribe&amp;body=subscribe%20testlist%0D%0Aexit%0D%0A" method="post" enctype="text/plain">
                <input type="submit" value="Subscribe via mailclient">
            </form>
        </body>
    </html>
    This is functional - except with Pegasus. The only parameter Pegasus accepts with mailto is "subject" (no cc, bcc, body and so on) and in addition Pegasus ignores the enctype. Sad
     
    The problem with all methods based on mailto is, that they won't be functional if there is no mailclient on backend. On smartphones most people I know use webmailers.
