RE: [Mailman-Users] Return to performance
Thank you all for the suggestions and references. I made some quick changes, especially the O Timeout.iconnect=5s sendmail option seemed to really help. I'm down to 4 to 10 minutes with most messages at 6. One question: Should I be looking at a better MTA? What is the fastest that works with RedHat 9? (I guess that is two questions...) Thanks!

[Mailman-Users] Return to performance
Dear all, In my last post on performance you gave me a lot of good advice. Some things that helped: Set SMTP_MAX_RCTPS back to default of 500 (I found a posting that said 3 to 5 was better, must have been an old version) Upped my RAM to 1.5 GB Rearranged how the machine saw the internet so my firewall was less of a choke on flow. I implemented all that I could and my send times are now down to from 5 to 30 minutes. I'd like to see better. Some facts on my setup: OS: Redhat 9 Mailman Version: 2.1 Hardware: 2.5 Mhz Athlon Drive: Single 40 GB MTA: sendmail (default with Redhat) (SMTPDirect) DNS Helper: pdnsd Network Connection: Full T1 from Sprint Usage: Average 12 Messages a Day, 8 in a four hour window from 6AM to 10AM Pacific Standard Time Subscriber: Around 2000, around 1/2 overseas When I check times I look at the time from when Mailman received the message till it shows up on my company mailserver (different machines on two different networks) 99.9% of my recipients are outside my LAN I am looking at disk utilization and see if that is hurting me as well. Something else that puzzles me is that some of the recipients seem to have very slow mail receivers, especially in India and China. Is there a way to find slow connections and group them together so they don't slow down everyone else? Thank you in advance for any and all advice! As I said earlier, this really is a very cool piece of software. I just want to make sure I am getting the most out of it.

RE: [Mailman-Users] Slow Performance on Mailman, Next Steps?
Dear all, I changed my SMTP_MAX_RCPTS to 500 as suggested. Now I'm averaging 20 minutes and as fast as 10. I suspect my firewall is a problem. It is issuing warnings about being overwhelmed. In that I've been away from Unix for almost 7 years now and I'm new to Linux, I really don't know what tools I could use to find my bottleneck. Any suggestions?

Dear all, We moved our mailman list over from yahoo to my server this week. No a painless move but it went OK. (This is some pretty good software!) My big issue is performance. Our list has 2300 subscribers and we do about 20 to 50 e-mails a day, nothing too big. Messages were taking 3 to 4 hours to be sent. I went through the FAQ on performance and have done the following to get down to 30 to 90 minutes: 1: Put in a DNS server on my machine with caching (pdnsd) 2: Used the following mailman settings: DELIVERY_MODULE = 'SMTPDirect' SMTP_MAX_RCPTS = 3 SMTP_MAX_SESSIONS_PER_CONNECTION = 100 3: Turned off the logging Some other facts: a: I'm running RedHat 9 Linux b: We are getting lots of bounces: 258 have been put on hold because they went over their bounce score c: I'm using a 2+GHz AMD machine. Lots of horse power and it seems like I'm not using much. CPU is sitting at between 5% and 10% So, my obvious questions are: I: Any suggestions on my mm_cfg.py settings? II: Anything else you can recommend? III: My assumption is that since I'm using SMTPDirect it doesn't matter if I use the default stuff that comes with Redhat or should I load something better? IV: Is it the bounces that are my problem? Thank you in advance for any advice!
