[Mailman-Developers] Mailman queue design problem?
Thu, 21 Jun 2001 18:51:18 -0700
As I understand it, mailman operates by receiving mail to one of 3
addresses (list, list-request, list-admin), flagging the message as a post,
request, or bounce/admin message, and adding it to qfiles. qrunner then
processes qfiles and handles everything.
This doesn't work for large lists. It has 2 major problems:
- large numbers of bounces prevent list mail and list requests from being
- a flat directory structure is a performance nightmare on non-btree dir
To be specific, the firewalls mailing list had accumulated over 20,000
bounces in qfiles, which was preventing anything from getting done, and
making the machine _very_ unhappy.
So I recommend a quick fix of splitting the queue into 3 parts, and a
medium term fix of adopting one of the tiered directory structures
(postfix, new sendmail, etc.).
