I have a dilemma. I have an Imail 7 server set that get a couple hundred thousand emails a day (call it Server A). I also have another one that gets about 80,000 a day( Call it Server B). My Server B works flawlessly. But Server A, Works about 60% of the time. I mean just the smtp doesn't work well. I try to telnet to it and I get "Connection fail" about 40% of the time.
3rd hand quote for Ipswitch to one of my clients having problems like yours (very hot Imail box couldn't accept much-lower-mail-rate-than-yours, many connection refused errors):
"default setting on the queue service of 4 listen pipes can go to 20 and had me increase it to 10... "
I look in logs form other server and it is a mix of the 10054 errors and the MX Fails errors. I check DNS and made sure those were all good, swapped from Netgear, to Intel to 3Com 3905 NICs and no avail. Also made sure power management is off.
Any ideas?
offload SMTP + DNS in/out from Imail to an SMTP gateway like IMGate, that will reduce the load dramatically, primarily by blocking 80% of incoming mail .
