I upgraded our firewall to v.8.202 yesterday morning. Told it to go straight from v.8.103 to v.8.202 via Up2date. The update has appears to be working fine. Greylisting, for e-mail, is enabled.
Yesterday I traded several e-mails with my business rep at our wireless carrier, one of the majors. All of his e-mails were delayed from 10 - 30 min from the timestamp. Not thinking about the upgrade, I assumed the problem was on his end.
This morning, I was again experiencing the same problem and decided to check the SMTP logs. Turns out my business rep friend was being greylisted, which is weird to begin with, because I trade e-mails with him probably at least every 2 months. And if he wasn't already greylisted, he should have been after yesterday's e-mail exchanges.
Anyway, I went ahead and added him to our exception list.
I then disabled and re-enabled greylisting. I'm under the impression that that will reset our greylist back to scratch - can someone confirm this?
Is anyone else experiencing any similar issues with greylisting after upgrading to 8.2xx?
