We have just received the below email from Port25.
Port25 just launched PowerMTA v4.0r13.
Below are a few highlights of this build:
modified DKIM signing to ignore “d=” and “s=” tags (in addition to “i=”) from the x-dkim-options header when looking up the key to use for dkim-identity-fallback, making it easier to ensure that a key is available for fallback signing
fixed vulnerability in web monitor that allowed HTTP headers to be injected when passed in a certain request parameter
fixed bug leading to DSN reports being dropped before the normal “bounce-after” interval when unable to deliver them
fixed .NET API rejecting “/” in job IDs
fixed SNMP daemon startup issues on 64-bit Windows
