Hi,
I was also looking at the prefork version from the 0.3x branch.
I just downloaded the 03x branch, and implemented the config as I was using
on 0.32. Some things won't work:
- It seems like config/smtpgreeting is ignored
- Quit doesn't work
It says: "221 closing connection. Have a wonderful day." But doesn't
disconnect.
- TLS doesn't work
Logdebug output:
-----------------------------------------------------
dispatching STARTTLS
tls
220 Go ahead with TLS
TLS setup returning
Plugin tls, hook unrecognized_command returned DONE,
500 Unrecognized command
dispatching EHLO [x.x.x.x]

Plugin tls, hook ehlo returned DECLINED,

Tested it with both Thunderbird and swaks, the output from swaks:

=== TLS started w/ cipher AES256-SHA

~> QUIT
<~* 250 <[EMAIL PROTECTED]>, sender OK - how exciting to get
mail from you!
=== Connection closed by foreign host.
-----------------------------------------------------
I've disabled all other plugins, and I've also tried to manually patch the
0.32 branch, but got the same results.
Am I missing somehting here? :)

Yes, I saw something like that (a little less, but my machines are
a little less also)

I'm sorry, I'm missing something.
I don't know anything about subclassing modules.
This is what I've done:
I've svn co 0.3x
Then copied config.sample to config (commented out almost all plugins file)
Then started the preforking server
./qpsmtpd-prefork --port 2525 --max-from-ip 5 --user leoh
connect to port 2525
But when you send the quit command, it never releases the connection
