Be aware of Soundex

We just ran into an issue where I user was removed from the Domino directory and the server had setup Fullname than local part for Mail lookup configured.
What happened is that the wrong user got the e-mail!

@Soundex

Returns the Soundex (the Lotus Notes phonetic speller) code for the specified string.

The phonetic name can result in the same short "hash" value for multiple names. There are a lot of collisions even for names that are not the same!.

I can only recommend to stay away from Fullname than Local Part for mail lookups. But if you can't you should be aware of @Soundex.

@soundex ("nsh@nashcom.de") for example returns N200.

I opened a support ticket and they pointed me to the following AHA entry. https://domino.ideas.aha.io/ideas/DOMINO-I-548

IMHO this feature request to allow Soundex to be completely disabled makes a lot of sense!

Hi Daniel,

I ran into the same problem some time ago:

https://blogbyrainer.wordpress.com/2018/05/17/addressing-users-in-ibm-notes/

I opened a case and received the information that it´s working as designed. But to be honest >> I'm with you to disable this "feature" ;-)

Best regards, Rainer

I have raised a change request to IBM to disable/remove @soundex and I noticed that you (Daniel) have commented & voted as well, thx! If others are keen to have this disabled, kindly vote to get the ball rolling.

Soundex should Never, Ever, Ever be used for routing email! It should be eliminated from all views used by the router.

@Richard, I agree at least 100% !!!

I will bring this up next week at the factory tour.
