Recipients with unquoted commas

Daniel Nashed  26 August 2013 10:40:02

There is an issue that is hitting almost every customer who receives messages from other mail-systems.

Many applications send mails in the following format Doe, John <john.doe@acme.com>.
The comma is a delimiter for separating addresses in Notes.
So the correct address would be a quoted address "Doe, John" <john.doe@acme.com>.

If you reply to an unquoted address you can run into very odd unpredictable results because Notes treats the entry as separate addresses and will lookup the first part in your Domino directory.
Unquoted addresses with a comma are not really RFC compliant but some email applications send mail that way.

There is a notes.ini setting that I did not notice before even it is around since 7.0.2.

notes.ini RFC822StripUnquotedDelimiters=1 on your SMTP Server should avoid those issues and also helps for encoded sender names that contain umlauts and other special characters.

IMHO this setting should be default.

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. This fix requires setting the Notes.ini variable "RFC822StripUnquotedDelimiters=1".
