I'm pretty biased towards from FreeBSD because of its development environment and the thoughtfulness of their engineering team (Linux is pretty hackish).

qmail is slow
Hi! I'm running qmail-1.03 + big-concurrency.patch + big-todo.103.patch + big-dns.patch + qmail-1.03-qmtpc-mailroutes.patch + badrcptto.patch + ezmlm, Daemontools-0.70, Ucspi-tcp-0.88, Qmail-conf-1.03, djbDNS-1.05 on Linux Debian 2.2rev2. Kernel 2.4.4. The Qmail was installed on a partition with reiserFS (17GB). The servers is a Dual PII 450 Mhz, RAM 512 MB. - conf: /var/qmail/control/concurrencyremote - 500 tcpserver accept incoming conection - 500 I have a central server with Qmail and Ezmlm and 4 server with qmail. MX Central Server | | | roundrobin dns in /var/qmail/control/mailroutes | | | ||||__Mail Relay1) |||___ MailRelay2)to ||MailRelay3 )remote host |_MailRelay4) Well, when the Qmail of Central Server send a list (for example) about 45.000 email subscribers, the Mail Relay's servers send about of 20 email at the same time. Its very slowly! But, when the Central Server finish, the qmail of Mail Relay send 500 mails at the same time. Why? How can I do for the Qmail process send/receive have the same priority? I need the qmail send a constant of 500 mails. Any idea? Thanks 4 all!

Because qmail-send is single-threaded, and must split its attention between processing new messages and passing processed messages to qmail-rspawn. How can I do for the Qmail process send/receive have the same priority? I need the qmail send a constant of 500 mails. Any idea? Don't pass the deliveries off to relays. In doing so, you're taking one message with 45000 recipients and making it 45000 messages with one recipient. How can I do this? without ezmlm? You might also want to set up a second qmail installation on the central server to do nothing but handle messages injected via SMTP. That will allow the qmail-send sending the ezmlm messages to go full speed by offloading bounce messages delivery to another qmail-send process. Ummmh..
