Excessive recursion error with plussed addresses

[William K. Hardeman]

Howdy all,

I've run into a problem where I can't get addresses with plussed parts to 
deliver. I'm getting an "excessive recursion" error in ruleset 3 (canonify) 
in my sendmail. Sendmail version is 8.12.6.

I'm using the virtusertable feature to support several domains, and the 
error only occurs when I use either
*+ at wkh.org	%1+%2 at wkh.org
*+ at wkh.org	%1%3 at wkh.org

If I remove those lines, emails are delivered without a recursion error, 
but only to the user's INBOX. I don't have any related aliases set in my 
aliases file for the addresses I've been testing, and there are no other 
lines in my virtusertable relating to @wkh.org for the address I've been 
testing.

I've also verified that my DNS tables are correct. All of my MX records 
point at A records.

Does anyone have any idea of what I could try looking at next? I'm 
completely stumped.

Thanks,
Will
