Re: Local Deliveries Slow
I hate to post unecessarily. But this is to thank everyone especially Charles Cazabon and Dave Sill. The Big To Do patch worked and my mails are zipping through (I run a very high volume mail server). I have successfully migrated my users from Isocor (critical path's messaging soln) to qmail. This is the second instance where my life got saved because of this great list.

Basically the problem is that qmail send will only process local and remote deliveries when there is nothing left in todo. Try applying the big-todo patch; it should help significantly.

Re: Local Deliveries Slow
I have already run the make check, etc and checked the permissions as per the LWQ. I have been observing this problem on my system for more than few days. Following are the observations. 1. When the incoming rate increases, qmail-send is unable to cope up. The todo increases at an alarming rate. After this the number of local deliveries suddenly stop (around 1 per sec). 2. After shutting down port 25 (to stop incoming mails) and giving some time for the unprocessed mails to become zero, the local mail delivery again become fast (I could get a concurrency of about 160) This is the current stats I have on my mailserver. isocor:/var/qmail/bin./qmail-qstat messages in queue: 67966 messages in queue but not yet preprocessed: 42007 and this is the output of qmHandle -s isocor:/var/qmailanalog/binqmHandle -s Messages in local queue: 27999 Messages in remote queue: 1418 Has anyone observed this and have come up with any solution to this.

Hi, I am having a tough time migrating to qmail. I have applied the concurrency patch and set the concurrency limit to 250. Inspite of that I do not see the qmail-lspawn forking more than 2 or 3 processes at any given point of time. What could be the problem? My local queue is currently at 8.
