Hi - well still no joy with this one, out of ideas. What I have found
though is that plently of people have had problems with SM and
firewalls. Not many answers to those who have. And none who have found
an answer have the exact same problem that I'm facing ;-)

Again testing on my servers internal address works but composing /
sending from my public facing IP *appears* to fail. Thought a snippet of
the Apache logs might be of use. The 1st is from the test against the
internal IP of my server:

192.168.246.174 - - [01/Jul/2005:13:24:24 +0100] "POST /src/compose.php
HTTP/1.1" 302 5 "http://172.27.14.1:100/src/compose.php?mailbox=INBOX";
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
192.168.246.174 - - [01/Jul/2005:13:24:25 +0100] "GET
/src/right_main.php?mailbox=INBOX&sort=6&startMessage= HTTP/1.1" 200
5158 "http://172.27.14.1:100/src/compose.php?mailbox=INBOX"; "Mozilla/4.0
(compatible; MSIE 6.0; Windows NT 5.0)"

The 1st line is when I click on "Compose" and the 2nd line is when I
click on "Send". This test works perfectly well, in fact all of the SM
install works.

Now compare this against when I use the public facing IP:

**my-ip-here** - - [01/Jul/2005:13:24:53 +0100] "POST /src/compose.php
HTTP/1.1" 302 5 "http://mydomain-here/src/compose.php?mailbox=INBOX";
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"

So I get the 1st line as with the internal IP test, but the 2nd line is
missing when I click "Send", the bit that calls "GET
/src/right_main.php?mailbox=INBOX&sort=6&startMessage= HTTP/1.1" that
just times out. And I get "Action canceled" in IE. I do receive the
email though!! And clicking refresh refreshed the screen.

Looking at these logs then maybe the problem is somewhere to do with the
call to "GET /src/right_main.php?mailbox=INBOX&sort=6&startMessage=
HTTP/1.1" and the firewall??

Anyway as ever, any help would be much appreciated.

Thanks - Julian.

Subject: Problem when sending an email


Hi - hoping someone can help me with a problem with a recent
squirrelmail build I have done, platform is:

Red Hat Enterprise Linux ES release 4
Qmail 1.03
Vpopmail
Mysql Ver 14.7 Distrib 4.1.12, for pc-linux-gnu (i686) using  EditLine
wrapper Apache 1.33 PHP 4.3.11 squirrelmail-1.4.2

The server itself is behind a PIX 525 firewall. The internet facing
address is accessed via port 80 and then translated to the actual
servers internal address on port 100. Apache is configured to listen on
port 100. Port 80 CANNOT be used as this is used for another Apache
instance running on that server.

If I goto the internal address, login and compose a message the email is
sent and received as expected. In fact ALL parts of squirrelmail work as
expected.

BUT if I goto the servers external address I can login and compose a
message BUT when I hit the "Send" button I can see that IE is "Opening
Page http://xxxxxxxxx/src/compose.php";. The right hand pane then goes
blank after about 20 seconds and I get the IE error "Action canceled".
BUT if I hit refresh, the page displays perfectly fine. I have tried
this on a Linux machine using Firefox and Konqueror with the exact same
results so I am pretty sure it's not IE being strange.

All other functions of squirrelmail work fine when I access the external
IP, just the "Compose" / "Send" part gives this error. DNS has been
checked several times which is fine.

Has anyone else seen this problem? I'm now completely out of ideas as to
why this happens. Any help would be appreciated.

Thanks - Julian.
