Automatic Attachment Compression in Incoming and Outgoing Emails

| Last activity: more than 10 years ago
All inbound or outbound emails would be scanned by ORF for attachments, then based on recipient and/or size of attachments, they could be compressed into one or multiple .zip files. This would reduce the load on the Exchange Store.

Run Specific Tests on Outgoing Emails

| Last activity: more than 10 years ago
Run selected content-based tests (Keyword Blacklist, Attachment Filtering, URL Blacklist etc) on outgoing emails as well. This is currently prevented by the IP Whitelist and the Authenticated User Whitelist. By ignoring these whitelists, outbound emails may be verified against malicious content (when submitted using SMTP).

Run Specific External Agents on All Email

| Last activity: more than 10 years ago
By ignoring all of the whitelists in ORF, run selected External Agents on every email seen by ORF. This would allow anti-virus software to run on outbound emails, too. This is is currently prevented by the IP Whitelist and the Authenticated User Whitelist. By ignoring these whitelists, outbound emails may also be verified against malicious content (when submitted using SMTP).

Sender Callout Verification

| Last activity: more than 10 years ago
Add a new test for Sender Callout Verifications. This type of test connects back to the email sender's server and attempts to find out if the sender is valid, by starting an SMTP conversation (no email is actually sent). If the sender's email address is rejected as invalid by the sender's email server, the sender email address is considered forged and the email is blacklisted. [Note from Vamsoft: The value and side-effects of this anti-spam technique is disputed in the industry. For instance, simultaneous Sender Callout Verifications from thousands of servers (as a result of a major spam breakout with forged sender email addresses) can result in a kind of Denial Of Service attack performed against the forged sender's email servers].
