Virtual servers will not go online with 4.7.676 installed, Microsoft told us to remove Avast! and the mail was flowing again. Seems somehow Avast! is interferring with SMTP flow.
Again this 2k3 server w/ avast un-installed works fine.
4.6.566 sort of works, however we’re starting to get the same errors.
Same problem here.
2-node cluster. Server1 without Avast runs perfectly. Server2 with Avast 4.7 fails after a couple hours. Server2 with Avast 4.6 runs a bit better, fails after almost a day.
