One final observation: I use Apache-SSL, and /etc/squirrelmail/apache.conf is included in httpd.conf With the default apache.conf, the error occurs. If I flip SSLDisable to SSLEnable (and moving the webserver to port 443) Things start working again. FYI: in httpd.conf (1.2.3.4 replaced with real IP, ofcourse!) Port 443 Listen 1.2.3.4:80 Listen 1.2.3.4:443 Listen 127.0.0.1:80 Listen 127.0.0.1:443 Finally, I flipped SSLEnable back to SSLDisable, and changed port to Port 80 and things still work! Even though the webserver listens to both port 80 and 443, apparently there *IS* a difference between the Port an Listen directive. Summary: Port 443 Listen 1.2.3.4:80 Listen 1.2.3.4:443 SSLDisable no virtual host http://myhost.foo.bar/squirrelmail/ Does *NOT* work Port 443 Listen 1.2.3.4:80 Listen 1.2.3.4:443 SSLDisable Using a virtual host (on port 80, obviously!) http://myhost.foo.bar/ *DOES* work Port 80 Listen 1.2.3.4:80 Listen 1.2.3.4:443 SSLDisable no virtual host http://myhost.foo.bar/squirrelmail/ *DOES* work Port 443 Listen 1.2.3.4:80 Listen 1.2.3.4:443 SSLEnable no virtual host https://myhost.foo.bar/squirrelmail/ *DOES* work Port 443 Listen 1.2.3.4:80 Listen 1.2.3.4:443 SSLEnable Using virtual host (on port 443, obviously!) https://myhost.foo.bar/ *DOES* work Still don't know if it's a Squirrelmail or an Apache problem, but this is as far as I could drill down the cause of the problem.
