The MUA lacks locking.  I would have to write it.

maildrop or procmail would solve the POP3 requirement.  stunnel is a 
more general solution available to other protocols.  As mentioned 
in the previous message, once stunnel is working the MUA can SMTP in 
Stunnel directly to the remote MTA.  If eventually I can remove exim, 
so much the better.

The MUA understands mbox and not maildir.

I see.  If qpopper can do it via locking why not make your local MUA to
do the same.

maildrop package comes with lockmail for such need.  (I suspect procmail
comes with similar util.)  You just have to use such thing.

Also, use of maildir format instead of mbox avoids locking issue.

Ideally the one mbox should work, but I'm not sure that the MUA and 
getmail will each respect access by the other.  qpopper will respect  
getmail in access to the mbox and respond to the MUA with POP3. This 
at the cost of a second mbox and delays up to the retrieval interval 
of qpopper.

Thanks.  Stunnel appears to be the right answer here.  The example 
in http://en.wikipedia.org/wiki/Stunnel with substitution of POP3 
for SMTP, is exactly the scenario I've described.

Further, the SMTP example allows the MUA to submit to the remote mail 
server directly rather than through exim4 on localhost.  The whole 
setup is simpler with Stunnel.

If Stunnel fails I'll consider that.

Thanks to everyone for all the feedback,... Peter E.

Cool :)
Are you able to compare getmail with mpop?

When I gave up fetchmail (a fine day :), a few years ago, mpop came
out trumps for me at the time - unbelievably fast!

I'm wondering what getmail could provide as compared with mpop.

I am soon to move from a webmail MUA back to mutt (it's been too long, I know).

TIA
Zenaan

You are using getmail + qpopper + some local MUA

Just make things simple by dropping qpopper.

By the way, mbox spool is not always good for you if you use noatime
filesystem.  getmail supports maildirs etc which may be better if your
MUA supports it.

I actually use mailfilter to split mail into many different mail box.
See:

It puts the emails to the user's mail spool via the local MTA (I use
postfix for it). Dovecot is also installed as an IMAP server so the user
can read it via IMAP also. Of course POP3 can be also provided.

Another candidate solution:

Move to a MUA which can do SSL/TLS.

But I bet thats the fixed thing in this scenario?

I'am using popa3d (Tiny POP3 daemon, designed with security as the
primary goal) and stunnel for SSL on server-side and mutt on client
side. I suppose all modern email client support mbox format (and POP3 of
course)

POP3 softwares.

2014-01-18 Thread Peter Easthope
Problem
Given a remote POP3 server which provides SSL.  Also a MUA on a
local host, which retrieves by POP3 when activated by the user and
lacks SSL.  Try to move messages from the server to the MUA.

Candidate Solution
Let getmail, in the POP3-over-SSL instance, retrieve messages from
the server and queue in an mbox file.  Run qpopper to allow the MUA
to retrieve from the mbox on demand.

Questions
1. Rather than getmail and qpopper, can one software do this task?
   If so, which is recommended?
2. The documentation for qpopper suggests that it can only acquire
   messages from a spool.  If the answer to 1 is "no", is there
   some way to pipe messages directly from the retrieving POP3 to
   the delivering POP3?

Thanks, ... Peter E.
