    I was probably not being clear, an explanation of Fetchmail's default
behaviour with users that do not appear in the system can be found here;
    However, this behaviour is changed very easily as a kind correspondent
on the Fetcmail list informed me.  Supposing our cyrus user is called
'auser', simply add < smtpname "auser" > to the command line or fetchmailrc
and  the mail is delivered to cyrus mailbox user.auser.  Thanks to yourself
and this other gent I am now rolling along at a great pace - just got to get
some kind of mail filtering going on.  Talking of mail filtering, you don't
know of any howto's etc dealing with sieve do you?  I have a
manage-sieve-perl script installed on my server, and a sieve daemon?
listening at 2000 but I haven't a clue how to use it and there seems to be
no official documentation.  Certainly b-all in the on the man page.
Thanks again for your help.
