Received a conduit error in SMTP Gateway:
"Network error occured, Unknown SSL protocol error in cnnection to aztec.brightmail.com:443 (35), check you network connection settings, check you proxy settings (if applicable), and check to ensure that port 443 (HTTPS) is open..."
This conduit error is normally generated and commonly ignored whenever the antispam rulesets are up-to-date.
I hope conduit error checking will be improved and will ony show relevant errors that need attention.
