qpopper, APOP, SSL and WebMail...


Hello,

I use qpopper with APOP and SSL. It works very well, i can fetch my mail with 
fetchmail or even directly from MUA such as kmail.
I don't know if APOP and SSL are a good idea. Maybe only POP over SSL would be 
sufficient ?

Now, i would use a Webmail. I did not find any webmail able to dialog in 
APOP/SSL. 

Can qpopper do APOP/SSL and classic POP ? 
I have "set tls-support = alternate-port" in my config file. Il try to change 
it to "set tls-support = stls" but it did not work.  Can i start two instance 
of qpopper with two different config file ?

BTW, do you know good webmail working nicely with qpopper ?

Best regards,

Curious I/O Error When Using SSL/TLS with a large mailbox

All:

I have been using SSL/TLS encryption with success for a while now,
however just today, I tried to receive a piece of email from my
mailbox which was about 20MB in size.  The POP server returned the
following error on each attempt.  The only way around this was to
retrieve the message without using SSL (i.e. in the clear).

My mail client is outlook.  Any idea why this error might be
occurring?  I am directly connected to the pop server over a dedicated
10M Ethernet, so no traffic issues.  Is there a file size limit in
OpenSSL?  I noticed that the mailbox was successfully copied to the
temp file before the errors appeared.  Lots of disk space available on
the server too, my client timeout is set to a minute (not the
issue).... thoughts?

Thanks
Keith

Re: Curious I/O Error When Using SSL/TLS with a large mailbox

I'm afraid that I don't have any solution but I too have been seeing this
problem for about a year now. I've noticed that several other people have
also posted emails regarding this same problem.

What I've discovered with this problem is that it does not actually appear
to be a qpopper problem or even a openssl problem.

I believe that it is actually an Outlook problem. I'm guessing that you are
using Outlook 2000 because I get the same problem often.

What I've noticed is this:

1) The problem is ssl related because when I get the error, I can still
retrieve
   the email if I try using non-ssl.
2) I have several MUA's on the same computer with the same network
connection
   and even though I get the error with Outlook, I can still retrieve email
   with Eudora, Mozilla, etc.
3) I can replicate this problem more consistently when the Outlook client is
   not on the same segment as the qpopper server.
4) I've called Microsoft about it but they were unwilling to help me, since
I
   was using qpopper.

An interesting thing I noticed was that if I flood the Outlook client with
network traffic and simulate congestion on that segment with something like
a ping -f outlookclient, the email will slowly start to work. LOL.

Although, it's not a great solution, you can always try a different MUA.

Stripping Domain names from the user name

I have just recently upgraded my system from qpopper 3.1 to 4.0.4

When I configured my system with qpopper 3.1 I had it configured so that if
a user entered userid <at> domain.com for their username, popper would strip off
the  <at> domain.com and just use userid as the user name.  The problem is that I
don't remember how I did this and I can't find it anywhere in the docs.  I
have looked in INSTALL, README, the FAQ and the pdf document.  I have even
looked in the config.status file (in fact I looked in all config. files)
from my 3.1 build directory and can't find anything.

Can anyone shed some light on this.

Thanks in advance!!!

In Qpopper 4.0.x there seems to be no option for that in the pre-compile
time configuration, but it can still be done.

Add the -C run-time option to your inetd.conf, something like this:

 pop3  stream  tcp  nowait  root  /usr/local/lib/popper  popper -s -C

Or if you use a run-time configuration file, add the trim-domain option to
it.

See the Qpopper Administrator's Guide for details.

It doesn't hurt to use APOP under SSL/TLS, but it isn't as important 
as in the clear.

That's what you need to do.  The Administrator's Guide (in the 
distribution) and the FAQ (on the web page) have instructions.

Isn't it dangerous to start two instance of qpopper accessing same mailbox 
even if it's not at the same time ? (pb of lock perhaps...).

I would get rid of APOP because it's useless with ssl, and I did not find any 
webmail supporting APOP...

So, two qpopper, or one qpopper managing pop/ssl and classic pop ?

Best regards,

Qpopper protects against this, by virtue of the .<name>.pop temporary
file.
