SMTP Engine
Posted: Mon Aug 17, 2020 9:09 pm
so i bee spending alot of time to the SMTP engine last few weeks and theres some things im gonna add to it.
anyone else see anything it needs please lemme know. Currently i am modifying the current galico smtp
engine with the following:
AUTH command to authenticate your session complete with a level 4 config option to allow/disallow unauthenticated transactions.
Ability to authenticate with the "smarthost" currently if you have to use a smarthost to process mail it just asks for the address and
not a name/password/port to authenticate with the smarthost.
when done the smtp server will support the following commands:
HELO
It’s the first SMTP command: is starts the conversation identifying the sender server and is generally followed by its domain name.
EHLO
An alternative command to start the conversation, underlying that the server is using the Extended SMTP protocol.
MAIL FROM
With this SMTP command the operations begin: the sender states the source email address in the “From” field and actually starts the email transfer.
RCPT TO
It identifies the recipient of the email; if there are more than one, the command is simply repeated address by address.
SIZE
This SMTP command informs the remote server about the estimated size (in terms of bytes) of the attached email. It can also be used to report the maximum size of a message to be accepted by the server.
DATA
With the DATA command the email content begins to be transferred; it’s generally followed by a 354 reply code given by the server, giving the permission to start the actual transmission.
VRFY
The server is asked to verify whether a particular email address or username actually exists.
TURN
This command is used to invert roles between the client and the server, without the need to run a new connaction.
AUTH
With the AUTH command, the client authenticates itself to the server, giving its username and password. It’s another layer of security to guarantee a proper transmission.
RSET
It communicates the server that the ongoing email transmission is going to be terminated, though the SMTP conversation won’t be closed (like in the case of QUIT).
EXPN
This SMTP command asks for a confirmation about the identification of a mailing list.
HELP
It’s a client’s request for some information that can be useful for the a successful transfer of the email.
QUIT
It terminates the SMTP conversation.
just a quick disclaimer..... this is just a modification of the current severely outdated smtp addon that comes with the galacticomm ico.
it is not intended to be a rip-off or clone of the current smtp addon just a modification to make it better.
when done i will have versions for both ico3 and ico2.
