Hi Frank,
Indeed, it looks as if my ISP broke something - this morning, things started
working again!
A close look at tcpdump on both success and failures revealed a difference
in the TCP window size:
Good:
17:17:50.752336 pop-server.110 > client.3339: P 111:128(17) ack 50 win 17471
(DF)
[...]
0x0020 5018 443f dbf6 0000 2b4f 4b20 3138 3636 P.D?....+OK.1866
0x0030 206f 6374 6574 730d 0a .octets..
Bad:
16:31:23.011154 pop-server.110 > client.3330: P 111:117(6) ack 50 win 5840
(DF)
[...]
0x0020 5018 16d0 1747 0000 2b4f 4b20 0d0a P....G..+OK...
My TCP is a bit rusty, but I wouldn't be surprised if it's an MTU problem.
I duplicated the problem with a straight 'telnet pop-server 110', so I don't
think it's a mail client problem.
I like the fetchmail suggestion, though.
Thanks,
Rony

I don't know of your answer, however, you could try setting up fetchmail to
get your mail and put it in a local user mailbox and set your own box to
serve pop3 for your client.. I have done that before sucessfully.
it seems most likely that your isp as changed something? what are you using
to check your mail? kmail, evolution, netscape mail, do they all not work?

Subject: [expert] POP3 fails suddenly under Linux (Mandrake 8.1)
Hi,
This is probably the wrong forum, but I'm out of ideas...
Setup: Dual boot machine connected to Internet via Alcatel ADSL modem, pptp
under Linux (Mandrake 8.1), or win2k.
For browsing and sending e-mail, both OS's are fine.
For the last few days, however, I am unable to retreive e-mail via POP3 on
Linux, while win2k works fine.
Tcpdump shows that the "RETR 1" command is accepted by the pop server,
which replies "+OK" and stops. (I don't have a sniffer for win2k.)
This used to work fine under Linux, and I have changed nothing in my
configuration. Before I get totally paranoid here, I'd appreciate any ideas,
hints or clues. Booting win2k to read mail is a bummer!
Thanks,
Rony
