The message field will look like this:
 
Object-Name: Name of the object that sent the email<br />
Region: The name of the Region (PLUS, in round brackets, the region_corner _coordinates)<br />
Local-Position: the local position of the object sending the email<br />
 
message_text
 
(Note: to be clear, the labels Object-Name:, etc, are actually returned to you as well.)
 
 
To get just the pure message text, minus the headers, do this:
 
<lsl>
message = llDeleteSubString(message, 0, llSubStringIndex(message, "\n\n") + 1);
</lsl>
 
 
To get just 1 of the header items, do this:
 
<lsl>
list TempList = llParseStringKeepNulls(message, ["\n"], []);
string objname = llList2String(TempList,0);
string tmpregion = llList2String(TempList,1);
string localpos = llList2String(TempList,2);
</lsl>
 
To get a pure region name, do this:
 
<lsl>
string right (string src, string divider) {
 
                integer iStart = llSubStringIndex( src, divider ) + 1;
                string result = llGetSubString( src, iStart, llStringLength(src) - 1 ) ;
      return result;
}
 
string left (string src, string divider) {
                integer iStart = llSubStringIndex( src, divider ) + 1;
                string result = llGetSubString( src, 0, iStart -1) ;
      return result;
}
 
list TempList = llParseStringKeepNulls(message, ["\n"], []);
string tmpregion = right(llList2String(TempList,1),": ");
tmpregion = llStringTrim(left(tmpregion," ("),STRING_TRIM);
</lsl>
 
 
 
This application uses email to have objects check with a central server to see if the owner has the latest version. In the objects:
<lsl>
string version = "1"; //
string type = "lolcube";
default
{
    on_rez(integer start_param)
    {
        llEmail("5a634b27-f032-283f-2df2-55ead7724b23@lsl.secondlife.com",
            version,
            (string)llGetOwner()+","+type);
    }
}</lsl>
The server:
<lsl>
default
{
    state_entry()
    {
        llSetTimerEvent(15);
    }
   
    timer()
    {
        llGetNextEmail("","");
    }
   
    email( string time, string address, string version, string message, integer num_left )
    {   
        if ((integer)version < 2)
        {
            list info = llCSV2List(llDeleteSubString(message, 0, llSubStringIndex(message, "\n\n") + 1));
            llGiveInventory(llList2Key(info,0),llList2String(info,1));
        }
       
        integer i;
        for (i = 0; i < num_left; i++)
        {
            llGetNextEmail("","");
        }
    }
}
</lsl>

Description

Event: email( string <span title="In the (string)llGetUnixTime format" style="border-bottom:1px dotted; cursor:help;">time, string address, string subject, string message, integer num_left ){ ; }

Triggered when task receives email

• string time – In the (string)llGetUnixTime format
• string address
• string subject
• string message
• integer num_left – The number of emails left in the email queue

Caveats

  • The email queue is limited to 100 emails, any email after that is bounced.
  • Due to bug SVC-23 (present since 2005), objects may stop receiving emails completely until either the region is restarted or the object crosses a region boundary (resetting the script doesn't help). Emails sent may eventually be received after a restart/region-cross. Hence, don't rely on this event for reliable inter-region messaging.
  • The entire incoming email is limited to 4KiB.
