Problem logging into sieveshell

[Jim Norton]

Hello all:

I am trying to get the sieve vacation thing working.
However,  sieveshell seems to be unable to log me in.

I never get a fail message,  it just asks me for a 
password 4 times then fails.

I am of course able to log directly into the imap server
via telnet hostname.com imap and then login.

Is it possible to enable sieve scripts without using
sieveshell?

Or,  does anybody have an idea about failing to log into
sieveshell?

Thanks,
Jim
