You've just reiterated the point everyone has already made... dump it to your MTA and allow it to handle the spooling and delivery.
but what exactly does it mean to "dump it to your MTA and allow it to handle the spooling and delivery"??
but *that's* what i'm asking about. i already know i need to give it to
the MTA (hence my original query) but i just don't know *how*. do i make
files and put them in a directory? and if i do need to make files what
is the format for an outgoing email or where can i read about the
format? OR do i use the commandline to individually send each email?
etc.
You've gravitated into questions specific to your programming task (which aren't kosher for this list). I don't know any php, so I won't be a lick of help. But, hopefully I can get you started in the right direction. First, the php Mail functions chapter:
http://www.php.net/manual/en/ref.mail.php
The RFC draft on SMTP pipelining:
http://public.research.mimesweeper.com/Standards/IETF/Draft/draft- freed-smtp-pipeline-02.txt
And a brief explanation of how pipelining is supposed to work:
"[T]he SMTP service whereby a server can indicate the extent of its ability to accept multiple commands in a single TCP send operation. Using a single TCP send operation for multiple commands can improve SMTP performance significantly."
In short, rely on your programming language's interface to the mail subsystem. If you have special needs (like pipelining), then use the extended interface available which supports those advanced features. I can't tell you where to find the answer, but I hope you can find it given this information. And one last thing, a way of telling if your MTA supports pipelining:
bash-2.05b# telnet localhost 25 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 mail.dixongroup.net ESMTP Postfix EHLO localhost 250-mail.dixongroup.net 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-XVERP 250 8BITMIME
Notice the 250-PIPELINING? :)
