754507 - Does not download from POP3 caused by firewall and no error message like "Timed out. Could not connect"

Status: UNCONFIRMED

(MailNews Core :: Networking: POP, defect)

Description

[Thomas]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 20120423122843

Steps to reproduce:

Click on "Get Mail".
It was working for several years and it stopped working out of the blue.
I deleted the popstate.dat but with no result. Compacted everything, but no change.


Actual results:

In the status bar I can see "Connecting to my-server...", but TB is not downloading any messages. But there are messages that I can see through webmail.


Expected results:

Should connect and download messages.

What is appearing in the error console? If nothing is meaningful there, try logging the connection: https://wiki.mozilla.org/MailNews:Logging

Use POP3:5 as the value for NSPR_LOG_MODULES.

I think I found the problem: the service provider has started to block POP3 with a firewall. So now I am using IMAP and TB is working again.

I think it is still an annoying thing that TB is only showing "Connecting to my-server..." and is not showing some helpful error message (like "Timed out. Could not connect." or something like that).

Really good provider that did not inform you about his decision months before applying it:)

Anyway, TB should inform about timeouts like that.
David Bienvenu, would a firewall dropping packets make a problem (in contrast to the server rejecting the connection on POP3 port properly)?

timeouts should work, but our connect timeout is a couple minutes, I think.
