    • Test: 2003-04-30 Eric Smith (eric-sqm at brouhaha.com)
  • Mozilla 1.2.1, Windows 2000
    • Status: Works mostly
    • Issues: All Attachments get a .php extension and application/octet-stream. Also, sometimes the server slows to a crawl with apache processes eating 98% CPU, while browsing big IMAP Maildir style mailboxes (well, "big" means about 1000 mails). I would like some feedback here as upgrading to Mozilla 1.3 went horribly wrong here (it simply refuses to connect to ANYTHING, don't ask me why).

  • Mozilla 1.0.1, Windows XP Pro, SquirrelMail 1.2.9
    • Status: Works great
    • Issues: Display preference "Display Attached Images with Message: O Yes O No" does not work as it does with IE 6. It does not display the images or provide the "view" link next to the attachment. The attachments also have a ".php" in addition to the ".jpg" (example bob.jpg.php) when downloading. This seems to happen only when mail is not sent from squirrelmail to a squirrelmail recepient.

  • Netscape 4.7 and 4.77 Mac OS 9.2
    • Status: Mostly Works quickly and beautifully
    • Issues: An address book entry with a very long addressess causes it to diplay the address book in a strange fashion. It seems to add a lot of white space to the right and bottom of the page, and then after momentarily flashing the addressbook to the user, it scrolls to the bottom right corner of the page. This makes the user see a blank right frame in the squirrel mail interface. It is not obvious that a user needs to scroll back to the upper left of the browser window to see anything.
