I have a server that I run apache, postfix, courier imap, and squirrelmail on. It was setup around six months ago and has been running very nicely - until a couple of weeks ago. I emerge updated system and world after rsyncing and thought that everything had gone well. Then I tried using squirrelmail...
Although squirrelmail still works, it is now VERY SLOW. The initial login is returned very quickly, but then the display of the next page takes 1-2 minutes (!!!!). Worst performance seems to be with anything which involves folders. The address and options pages display quickly.
I normally use the Mozilla IMAP mail client with this server and that is working normally (very quickly). My primary use for squirrelmail is for reading mail when I travel (which is why it took so long to discover the problem...).
I've tried reinstalling squirrelmail, but that doesn't seem to help. I'm fresh out of ideas. Any help would be most appreciated.
