Hello All,
I have been using mailman+sendmail on a CentOS Linux VPS box, with 2 x Intel(R) Xeon(TM) MP CPU 3.66GHz CPUs, and 2 GB RAM. The list is of around 65000 users.
Form the past few weeks server seems to be very slow in delivering mails. I have been receiving mailer approximately with 2 hours delay.
*******Mailman is taking 30979.910 seconds for 65660 users******* Oct 31 10:02:28 2010 (7270) <201010310625.o9V6PY9t028494@xyz.com> smtp to xyz for 65660 recips, completed in 30979.910 seconds
*******Whereas another server with came Specs and configuration is just taking 12517.834 for larger (79579) number of users.*******
Oct 31 19:10:25 2010 (12027) <201010311653.o9VGrCqX024525@abc.com> smtp to abc for 79579 recips, completed in 12517.834 seconds
Can you please suggest me how to improvise the performance of mailman or how about if I want to migrate the mailman from Sendmail to Exim ?
Regards, Ajay
