I installed 7.300GA on two boxes Saturday afternoon, a few hours after first installing 7.202. I made very few changes to the new "default" settings.
Box 1:
HTTP, SMTP and POP proxies are running here. Reject Malware and SPAM at SMTP were both on. All SPAM checks are on, including the new HELO/RDNS test, except Greylisting.
When I looked in on box 1, the swap file was over 30% of 1Gb overnight (about 20 hours). These swap files have never grown like this before. No one was in the office. There were 1280 inbound e-mail attempts and 1250 of those were confirmed? SPAM. So about 30 possible good messages - all very small.
I restarted the SMTP, POP and HTTP proxies, but that didn't clear anything. So I restarted the box and checked again. Swap was back to zero.
Then I changed from SMTP Profile mode to SMTP Simple mode. 5 hours later - early Sunday evening, swap file is again climbing - at 12% of 1Gb - and growing.
Box 2:
HTTP and POP proxies are running. No SMTP proxy running here.
No growth in the swap file at all. Still at zero.
Question:
Is this normal behavior for the new SMTP proxy? It's definitely different than in the 7.2x versions.
