pop server access?

pop server access?

[Norbert Koch]

Hi Lars, 

have you made any changes regarding the pop server access? I can't get
onto the server after the installation of 0.35.

Hmm, any point I can start debugging?

TIA, norbert.

This patch was applied to make things work under Emacs 20.3:

It looks a bit weird to me, now that I think about it.  Why has the
`pop3-read-point' setting moved downwards?  I'll move it back up.

Ratinox, I know you don't like Muletilations of pop3, but it is
necessary it it's going to work in that release.

Hmm, the problem still exists after an update to 0.36. C-g comes up
with

At this point the system seems to hang (well, I don't know for how
long, I'm sort of impatient :-).

Any leads? Tia, norbert.

Could it be that you run Emacs in unibyte-mode, then?  It was I who
made the bug report, after detecting that pop3.el did not work in
multibyte-mode (CRLF pairs from the pop server were translated into
mere CR's).  Switching to unibyte made it work for me before the fix.

Probably because I submitted a bugreport and patch to rms, which was
based on the pop3.el of Emacs 20.3, where the setting is positioned
down there.  I don't know why.

Hi,

odd enough this works like a charm. I'm also able to pop my mail using
earlier, ie pre 0.35, versions from pgnus. All the fuzz has begun
happening using 0.35/6, damn :-(

Hi ratinox,

first of all, thanks for the time you spend on helping me solving this 
problem (it still exists on 0.39)

So, here we go. I've written a simple test mail and retrieved it by
telnet.

I've now updated to qpopper-2.52 and pgnus-0.40 and still run into the
same troubles.

The one thing that strikes me is that I'm the only one who has this
problem. Therefore, I guess, the real culprit must lie somewhere else
in the system configuration, although I can't remember of any other
things I could have changed in the meantime.

Oh what the hell, I postpone the issue for a couple of days. Maybe,
(the) something slips back into my mind :-)

Cheers, norbert.

Yup, no help with it.

<offtopic>
since you reminded me ... I had to switch back to the old qpopper
version, since nobody here was able to retrieve mail with the new
version installed. It didn't accept any passwords. I have shadow
password enabled. Do you know about any problems with this (not
shadowed passwords, fetched via NIS, seem to work)?

L8er, norbert.

This bug is because of MULE. Stainless Steel Rat fixed it in FSF Emacs
20 by adding 
	(coding-system-for-read 'no-conversion)   ;; because FSF Emacs 20
	(coding-system-for-write 'no-conversion)  ;; is st00pid

But Norbert Koch's pop3 does not work because of XEmacs 21.2.

My solution is using "binary" as the coding system. "binary" is alias
of "no-conversion" in FSF Emacs 20, "nil" in XEmacs 20 (hope it works
in XEmacs 21). The patch is attached.

[I think in this case FSF for being a changing target to stay
compatible with and ignoring the prior mule implementation in Xemacs.
However it does't really matter.]

Sigh, it just that
there is

binary    -- Fully transparant
raw-text  -- just EOL conversion

These work in both Emacsen.

On FSF Emacs no-conversion == binary and the documentation talks about 
no-conversion in that context.

On FSF XEmacs no-conversion == raw-text and the documentation talks about 
no-conversion in that context (minibuffer also shows the raw text
coding system as NoConv).

So if we could just get both .texi files to just talk about binary and 
raw-text and let no-conversion die that would be very nice.

Jan

P.S. To add to your pain there is also EOL conversion in non-mule
Emacsen (for DOS/Win support).
