This was just discussed on the list yesterday.  Dovecot caches user
information in memory and does not support roaming users.  You will
need to switch to SMTP authentication.

POP-before-SMTP is *bad*.


Is there a simple resolution to resolve this issue?  I have looked at
SMTP-AUTH but not sure it will work with vpopmail.


It works.  Just be sure that you have clear passwords enabled in
vpopmail if you want to support CRAM-MD5 authentication.

Matt what smtp-patch do u suggest!  Can u point me to a current howto?



After reading http://www.fehcom.de/qmail/smtpauth.html this  
morning, I'm hoping for a good answer to Davis' question as well.   
Do you think the guide at the bottom there is the way to go?


Is migrating to postfix (still with vpopmail) a viable / advisable  
alternative?


thank you all very much,
Joe








I use qmail-toaster (http://qmailtoaster.com), which includes the  
following qmail patch:

Robert Sander - qmail-remote-auth
http://www.ornl.gov/lists/mailing-lists/qmail/2002/03/msg00091.html

You also might consider using spamdyke (http://spamdyke.org), which  
provides a vpopmail authentication mechanism (when configured  
appropriately). I highly recommend using spamdyke, whether you need  
it for authentication or not. It can stop 80+% of spam before even  
receiving (or scanning) it. It will lighten the (scanning) load on  
your server considerably.

Looking over the docs, spamdyke looks perfect!  I'm downloading and  
installing now.  I love that I can try it without recompiling Qmail,  
and if there are any problems, simply switch right back to the current  
"no smtp-auth" setup by updating the run file.  If it works, this is a  
much better solution than I hoped for!  Thanks Eric.
