Hi List, I can't find the right answers/solution to this one in the archive, but perhaps I didn't search good enough. I apologise for that. I'm using squirrelmail 1.4.4, with courier-imap 3.0.8 and php4.3.10 on an Debian 3.1 system. All stable software, installed with the package manager (aptitude). The system is kept up to date on a daily basis. Squirrelmail and courier-IMAP are on the same server. Above setup is times 3, for redundancy. On all 3, all works as expected. HOWEVER: Installing this on a fourth machine, in exactly the same way, gives me 'connection unexpectedly terminated' when adding/deleting folders. I've compared the settings of about everything now, but I can't find a difference, causing this behavior. I've found some info about the software being unable to determine protocol/port, and changed that in functions/strings.php (line 257), but that didn't make any difference. I even snooped the IMAP conversation (using TCPreen), but that appears to be working okay. TCPreen 'sits' between client and server, and logs the TCP data which passes by. I let it listen on port 1143, and let it forward to port 143. In squirrelmail I change the port to 1143, and make a connection. All works, except creating/deleting folders. They are indeed created and deleted, but the popup shows, and the window is not closed. the IMAP conversation is exactly as expected. When I change the setup to use one of the other servers, the problem persists. If I use eg Thunderbird to connect (from localhost, too), it works fine, both directly and through TCPreen. Conclusion: it is a problem in Squirrelmail Anyone to point me in the right direction? TIA! Marcel ------------------------------------------------------------------------- Take Surveys. Earn Cash.
