Hello list, I have just set up 2 mail-servers that act as MX for nearly 400 domains and are used by a restricted group of clients for sending mail to the world The "problem" is that sometimes the smtpd connection is slow (about 3 or 4 seconds) to send an email. By the hardware point of view the servers are powerful. Suggestions? -- Andrea Berardi aka Syneus Linux Registered User #395193 http://counter.li.org/
