Re: [Nmh-workers] preventing change of current folder with rcvstore?

The pithy ruminations from rader(_at_)hep(_dot_)wisc(_dot_)edu on 
<Re: [Nmh-workers] preventing change of current folder with rcvstore? > were:
=> 
=> I think you have a weird rcvstore?!  Mine doesn't change the
=> default folder.


Hmmmm......

        /usr/libexec/nmh/rcvstore
        rcvstore -- nmh-1.3 [compiled on x86-4 at Thu Jun 19 13:40:10 EDT 2008]


Hmmm.....

        [bergman(_at_)mirchi .procmail]$ folder +junk
        junk+ has 3 messages  (1-3);        (others).
        [bergman(_at_)mirchi .procmail]$ echo hello | /usr/libexec/nmh/rcvstore 
+inbox
        [bergman(_at_)mirchi .procmail]$ folder
        junk+ has 3 messages  (1-3);        (others).
        [bergman(_at_)mirchi .procmail]$ echo hello | procmail
        [bergman(_at_)mirchi .procmail]$ folder
        junk+ has 3 messages  (1-3);        (others).
        [bergman(_at_)mirchi .procmail]$ 


You're absolutely correct.

[Scratches head]

So, what's causing the default folder to change? I assumed that it was 
rcvstore, as called by procmail, but that's clearly not the case.

Thanks,
