I submitted a command to ListProc and got this funky email back...




Youth Guardian Services uses software called Listproc to handle the subscription (and mailing) processes of the YOUTH Lists. Listproc has a limited vocabulary - it can only understand a few key phrases and words. Anything else submitted to it will generate an error message.

If  you submit a request to the Listproc, and it doesn't understand what you submitted, you will get an email back with the subject saying:

"Error Condition Re: Invalid Request"
 

Upon opening the message, there will be the following:

>Do You Yahoo!?
Unrecognized request "DO"

If you wish to contact a person, please send mail to
list-admin@Youth-Guard.Org.
To get general help on Listproc, please send the command:

    HELP

in the body of the message to listproc@Youth-Guard.org.

PS: Any subsequent requests you might have submitted in the same
message have been ignored.
 

You may not recieve an error message exactly like this one - the line beginning with the ">" indicates the line in your email that caused the Listproc Error. There are several errors you may receive. The most common ones are listed below. You can click on the one that is most similar to the one you received to read a more detailed explanation.

1.     ><HTML><FONT FACE=arial,helvetica><FONT  SIZE=2 FAMILY="SANSSERIF"
        FACE="Arial" LANG="0"><B>subscribe youth17-21 </B>Adam</FONT></HTML>

6.     >Do You Yahoo!?
       Unrecognized request "DO"

7.     >__________________________________________
       Unrecognized request "__________________________________________"

8.    I got an error message, but it doesn't look like any of the ones above.
 




><HTML><FONT FACE=arial,helvetica><FONT  SIZE=2 FAMILY="SANSSERIF"
FACE="Arial" LANG="0"><B>subscribe youth17-21 </B>Adam</FONT></HTML>
Unrecognized request "<HTML><FONT"

This error message is generated mostly from AOL users who have defined various colors and fonts to use with their AOL e-mail. However, in order to do this, AOL uses HTML in the email, and that in turn confuses the Listproc software. The Listproc is trying to interpret the HTML code, but it cannot. Please note, however, your subscription request has been submitted to the Subscriptions Manager, and will be processed in the next few days. There is no need to resubmit your request.
 




>This is a multi-part message in MIME format.
Unrecognized request "THIS"

This error message is generated because the email client you're using (Outlook, Outlook Express, Netscape Messenger, Eudora, Opera, etc) has been set to send outgoing mail as HTML or Rich Text mail. MIME is the standard format used when sending e-mail - it allows other email clients to interpret what you've sent. But MIME format confuses Listproc and it generates an error message. Your request has been submitted to the Subscriptions Manager and there is no need to submit it again.
 




>subscribe youth17-25
SUBSCRIBE: Unknown list name YOUTH17-25

>unsubscribe
UNSUBSCRIBE: Missing list name

 In order to be subscribed or unsubscribed from a YGS email list, Listproc has to know which list to perform the action upon. Misspelling the list name will cause an error like the first one; leaving out the list name will cause an error message like the second one. Valid list names are:

      Please note - those are the list names as recognized by Listproc. Anything else will not be recognized. So 'Youth 13-17' or 'PFLAG DISCUSS' won't
      work.

      If you receive an error message like this one, your request has not been submitted to the Subscriptions Manager. You must resubmit your request  in
     order to be subscribed to a YGS email list. If you wish to be subscribed to a YOUTH list (YOUTH13-17, 17-21, 21-25 or STR8), please visit our
     subscriptions page. Using this page will ensure that your email is in the correct format and will not cause any errors to be generated by ListProc.
 




>suscribe youth13-17
Unrecognized request "SUSCRIBE"

This error message is also a very important one to take note of - Listproc is unforgiving of typographical errors. The word 'Subscribe' must be spelled correctly; capitalization has no effect, but the letters must be in the correct order. The same goes for 'Unsubscribe'. Once again: If you receive an error message like this one, your request has not been submitted to the Subscriptions Manager. You must resubmit your request  in order to be subscribed to a YGS email list. If you wish to be subscribed to a YOUTH list (YOUTH13-17, 17-21, 21-25 or STR8), please visit our subscriptions page. Using this page will ensure that your email is in the correct format and will not cause any errors to be generated by ListProc.
 




>Do You Yahoo!?
Unrecognized request "DO"

>__________________________________________
Unrecognized request "__________________________________________"

These error messages are usually generated by the use of web-based email systems, such as Yahoo.com or Hotmail.com. Yahoo and Hotmail both insert line at the bottom of every email you send - even if you don't know it. Yahoo inserts the 'Do you Yahoo?' line, and Hotmail inserts the '_____________________________' at the end. In either case, these errors may be ignored. Your request has been received by the Subscriptions Manager and will be processed normally.
 




There is one other type of error message that you may receive, but it cannot be listed. That's because those errors are specific. These kinds of errors are generally caused by submitting a real email to Listproc, as if you were writing to a person. However, Listproc isn't a person, and can't understand what you're saying. It will just take the first word of what you say, see if it matches a command, and if it doesn't - it will generate an error message to you, similar to the ones listed above.

For example, you can get an error message like this:

           >Hi! My name is Jack and I'd like to be subscribed to the youth 13-17 mailing list. My birthdate is
          Unrecognized request "HI!"

Listproc is trying to make sense of what you wrote - but it can't. Notice it will only pick up the first word - that's because as soon as a space appears,
Listproc stops, tries to process what came before and sees if it's valid. If the command is valid, it will move on to the next word and continue on its way.
But if the word before is invalid, it grinds to halt and sends off the error message, never processing anything after the first word. That's why in the error message
email, it says:

          PS: Any subsequent requests you might have submitted in the same
          message have been ignored.

This prevents Listproc from generating an error message for every word in your email.
 

Each error message is also sent to a real person at Youth Guardian Services - that person will get in touch with you if the error requires intervention.
 

If you have tried to submit a request to Listproc, but can't seem to get it to work right, email list-admin@youth-guard.org and someone there will be able to help you out. Most of the guidelines here, however, should help resolve most matters.

Hope to see you on the lists!
