SPR# CEMABAVNMT RFC822 addresses with unquoted commas and semicolons in a friendly part causes an issue on the Domino server mail addressing. RFC822StripUnquotedDelimiters serves as a work around in fixing the issue
From the SPR# JALS658T7S – Mail is parsed into two separate addresses on a reply/reply with history.
This fix prevents splitting of RFC822 addresses caused by unquoted commas and semicolons in a friendly part. This fix requires setting the Notes.ini variable “RFC822StripUnquotedDelimiters=1”.
But on some cases, setting the parameter to RFC822StripUnquotedDelimiters=0 will workaround the issue for inbound SMTP when User in the TO field goes to the BCC field when entering a Domino 10.0.1 server
Permanent fix will be available in Domino 10.0.1 FP2. SPR# CEMABAVNMT
