Possible dupe of bug 194238. Reporter, do you still see this with a trunk build dated 20030324 or newer, where 194238 was fixed?
Reporter (Chaminda): Please report whether this bug is still a problem for you, using a more up-to-date version of Mozilla (1.5 preferred, or 1.4 if necessary).
Junk mail filtering stopped working in Moz v1.4 with multiple IMAP accounts. It had been working quite well for the last week. I decided to run the Junk Mail Filters against a folder that had nothing but several thousand already filtered junk emails with the idea of 'training' the junk mail filter. After filtering about 1000 messages (out of 8000) I got a dialog box with an error message saying the the 'Command to the mail server was too long...' and the junk mail filtering stopped. I quit and re-started Moz v1.4 and tried the same folder again using the Tools->Run Junk Mail Controls on Folder. This time nothing happened. I gave up troubleshooting at that time. Later I discovered that the Junk Mail controls were no longer enabled. I re-checked the 'Enable Junk mail controls'. I also quit and restarted Mozilla. Since that event however, none of the junk emails coming into my IMAP inboxes on 2 accounts are being flagged as junk. When I run Tools->Run Junk Mail Controls on Folder, nothing gets flagged as junk although, I do see a message on thelower status bar saying: 'Downloading messages...' I also observe high CPU utilization for a few seconds. However, no messages are flagged as junk. I decided to upgrade to Moz v1.5 (Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.5) Gecko/20031018). The exact same thing happens - nothing is flagged as junk and when running it manually although I see 'Downloading messages...' and high CPU usage, none of the spam messages in my Inbox (or any other folder) gets marked as Junk. I suspect that the Junk Mail database that stores 'learned' information has become corrupted and now, although junk mail filtering is occuring - no messages are every flagged as junk due to a corrupted junk mail database. I believe that if I wipe out the junk mail database and let it start re-learning again that it will likely continue working. It is quite possible that the junk mail controls/database simply can't handle a huge volume of junk email. I typically receive over 2000 (yes, thats 2 followed by 3 zeros) spam messages per day. Most if that junk is pre-filtered and filed using a conventional Mail Filter. However, some junk gets thru to my inbox (about 100 or so every day) and I was just starting to use the built in junk mail controls as a last line of defense. The Junk email controls are promising however - not having any access and/or control of what is 'learned' is a significant disadvantage.
Bob Atkins, it is possible you have encountered bug 192119 or bug 213300. (The latter has some discussion of how some antivirus software can interfere with the junk processing.)
After reading bug 192119 and bug 213300 I can confirm that neither of those bugs is playing a role in the problem that I am reporting here. I am running on Sun/Solaris and I am not using a virus filtering program that intercepts the incoming email. I have confirmed that after deleting the junk 'knowledge' database (traning.dat) and restarting mozilla that junk mail filtering starts working again. Over time I have noticed that the effectiveness of the junk filtering falls off. I have also avoided allowing the junk filtering to run against my 'Junk' folder or any other folder where I store purely junk email. Before selecting one of those folders I have to go through the trouble of turning off the Junk email controls. I had found a couple of other bugs (now I can't find them) that seemed to relate to the problem that I am reporting here. I believe that the Junk filtering function needs to allow for certain folders to be listed as 'ignore/do not evaluate'. It is a major hassle to have email in my Sent or Drafts folder flagged as junk (for what reasons I do not know). If I select one of the folders that I keep spam in - Mozilla will all but lock up while it examines all of the stuff (usually several thousands) that I already know is junk. Such a case of over training seems to kill the effectiveness of the Junk email knowledge database and after attempting to evaluate all of the email in any folder that only contains spam I need to delete the training database and let thing s start fresh in order to get any Junk filtering to work in the Inbox.
Bob Atkins: See: bug 200087: Junk classification effectiveness peaks and then falls over time and bug 196964: Add folder properties to allow user to disable automatic junk mail analysis on a per folder basis Chaminda, still waiting for a status update from you.
