Re: ESMTP AUTH and qmail
If you are doing load sharing between machines. then your best bet is to use the ucspi-mysql.patch That was released about 2 weeks ago.. This allows you to look off a Mysql TABLE instead of using the CDB file.. (I have ran into many problems with my machines.. Doing DNS load balancing for SMTP) I was running into NFS file locking problems when I implemented the POP3 to SMTP authenication.

The tcprules .cdb file is generated/updated atomically, so why not share a single copy of it among your SMTP servers? Have relay-ctrl share a directory across the POP3 servers, putting their entries in a common directory, and updating the same .cdb file. Then it should work fine, no matter how the connections get distributed. Of course, there's slightly higher risk due to having the NFS server which hosts this directory and .cdb file as a single point of failure.

ESMTP AUTH and qmail
Is there a patch for qmail that enables the ESMTP AUTH authentication scheme (RFC 2554)? I've looked about at qmail.org, but didn't see anything obvious (forgive if I overlooked). My original plan of using something like relay-ctrl for SMTP-after-IMAP fell through when I remembered the system I am putting together will use multiple load-shared machines, which means the machine handling a user's outgoing message may not be the same machine handling his/her IMAP connection. So, I need something that works with SMTP directly, or otherwise doesn't require something that might break when multiple servers are involved. Thanks for any help! ---Kris Kelley
