actual external source IP:host be used in exim instead of the IP of the
proxy that is connecting to it.
- 2. When built with OpenSSL the smtp transport now supports options
+ 2. New verify option header_names_ascii, which will check to make sure
+ there are no non-ASCII characters in header names. Exim itself handles
+ those non-ASCII characters, but downstream apps may not, so Exim can
+ detect and reject if those characters are present.
+
+ 3. New expansion operator ${utf8clean:string} to replace malformed UTF8
+ codepoints with valid ones.
+
+ 4. New malware type "sock". Talks over a Unix or TCP socket, sending one
+ command line and matching a regex against the return data for trigger
+ and a second regex to extract malware_name. The mail spoofile name can
+ be included in the command line.
+
+ 5. When built with OpenSSL the smtp transport now supports options
"tls_verify_hosts" and "tls_try_verify_hosts". If either is set the
certificate verification is split from the encryption operation. The
default remains that a failed verification cancels the encryption.
