SL Mail V1.2

Updated: 10-2-2011

Second Life mail client

Send and receive email from within Second Life from and to any address.

Implemented with Address Book function (in a notecard named 'Address Book') to stores addresses by name and to compile groups of named addresses. Current version is stand-alone (no server functionality) and uses chat commands only.

URL: slmail.info (website coming soon!) url slmail.info no longer used for SL Mail, and was taken for some other purpose.

Release Notes V1.2

SL Mail V1.2 Release notes (edition 2, 4 sept 2007)

IMPORTANT NOTICE

Development of SL Mail was abandoned midyear 2008. The domain slmail.info was abandoned and is now taken by another domain holder (ISS) who has nothing to do with SL Mail.

SL Mail is considered for redevelopment under the same terms, using a version of the Serverless Key Exchange script. This allows mail clients to exchange their key adresses to other rezzed mail clients in world, and send each other info about the public name they use, and other info that could be usefull. This protocol does not use a central server.

See: Serverless Key Exchange

Future annoucements about SL Mail development will be made here.

DESCRIPTION

SL Mail V1.2 is a simple tool to send and receive mail from within SL. You can either compose a message yourself using chat recording, or choose a notecard from inventory to send. The Address Book functionality allows you to use short names for mail recipients stored in a notecard. The current version does not have a persisent mail address. Watch out for the upcoming next release (V1.3) which will facilitate persisent in-world mail addresses and will be enhanced with many new features (See: Requests For Change (RFC).

COMMANDS

Command	Description
@Help	Show Help about available commands
@Record	Starts a chat recording (for owner only).
@Stop	Stops the chat recording without sending

@Send	If recording, stops the recording, and sends the mail (need to supply mail address and subject first!)
@Send <notecard>	Sends the content of the notecard, instead of the chat recording.
@Ignore	Ignores your current chat recording.
@Mail <address>	Define the mail address to send to.
@Mail	Shows the current mail address to send to.
@Subject <subject>	Define the subject of the mail.

@Home	Show the HOME address.
@Info	Shows the mail address the object this script is running in uses (e.g. <object-key>@lsl.secondlife.com).
@Read	Reads the current message from the mail buffer (the mail buffer gets filled with mail you receive)
@Select <msg>	Select a message number from the availabe messages in the mail buffer.
@Next	Make next message the current message.

Note:

ADDRESS BOOK FORMAT

A notecard of the name 'Address Book' is read during initialization which may contain Address Book items and Groups. The notecard is split in two sections, which need to be defined in that particular order.

[ADDRESS BOOK]

Defines the section in which you can put names for mail addresses, like this:

Name1=account@thisdomain.com

Name2=user@otherdomain.com

etc.

[GROUP]

Define groups of previously defined names under a new name, like for instance:

MyGroup=Name1, Name2

Note that names of groups and individual mail adresses share the same namespace and must be unique.

So when you filled in your mail adresses in the Address Book, you can now use:

@Mail Name1

To send mail to <account@thisdomain.com>

or you can use

@Mail MyGroup

To send mail to <account@thisdomain.com> and <user@otherdomain.com> Mails will be sent one after another.

Notes:

• Names for Addreses and Groups are case insensitive (e.g. "mary" == "MARY")

• The special address 'Self' can be used in commands where otherwise an address specification can be used. 'Self' is case insensitive (e.g. "self" == "SELF")

LIMITATIONS

The current version is limited by the following:

• Chat recording lines are limited by the 255 byte limit

• Output of lines from the mail buffer are also limited by this 255 byte limit

• Incoming mail is limited to a 1000 (1024?) byte limit

• Outgoing mai is limited by a 4096 byte limit, which includes the standard mail header (region/location info on the first two lines)

We are making adjustments to this release to help overcome these limitations. At least the line lenght limit can be overcome by introducing a line continuation character (for example a hyphen '-') that when used at the end of a line appends the next line, so lines longer then 255 bytes are possible then.

To overcome the outgoing mail length limit, the mail can be broken textualy into parts, and each part can be send seperatedely, with an indication in the subject or in an introduced primary line of the mail body to indicate that the mail was split into parts. For incoming mail and at least to receive mail from other SL Mail programs, a protocol will be introduced to receive mail in parts that are joined together after receiving them to form a single mail.

These enhancements will be made available in the next release (V1.3) of SL Mail

BUGS

Report any bugs you find in this release to Logic (IM: Flennan Roffo).

REQUEST FOR CHANGE (RFC)

Do you have additional wishes for enhancement of this product? Contact Flennan Roffo and we will see if they can be implemented in the next release.

Existing RFC's are:

• Menu support for commands.

• Lines on incoming/outgoing mail longer than 255 bytes.

• Send messages longer than 4096 (minus SL mail header) bytes.

• Receive messages longer than 1024 bytes.

• Permanent mail addresses for the SL Mail client (like: <Flennan.Roffo@somedomain.sl>)

Add your RFC!

//
//  Notes:
//  1. Group and Name share the same namespace, and must be unique.
//  2. It is allowed to have a name in the addressbook with multiple addresses, seperated by comma's.
