zmtrainsa --cleanup not fully cleaning up

[ewilen]

I've noticed that some mails are getting left in the spam account for extended times. E.g. I just ran a test by doing
/opt/zimbra/bin/zmtrainsa >> /opt/zimbra/log/spamtrain.log 2>&1
/opt/zimbra/bin/zmtrainsa --cleanup >> /opt/zimbra/log/spamtrain.log 2>&1

Then I looked in spamtrain.log and saw:

20090730122011 Starting spam/ham extraction from system accounts.

As you can see, 12 fewer messages were processed by cleanup than by extraction. I confirmed this by looking in the spam account's inbox. Then I ran the two commands again and looked at the log:

20090730122241 Starting spam/ham extraction from system accounts.

So you can see the final 12 messages were extracted/processed AGAIN (potentially overweighting their contents?) then cleaned up.

Any idea why this is happening? The only clue I can suggest is that the cleanup might be missing messages marked as "read" (due to my browsing the spam account) but I don't think it is actually following that pattern.

I know this thread is nearly 4 years old, but I have the same problem in my spamtrain.log:

Learned tokens from 292 message(s) (673 message(s) examined)
Learned tokens from 0 message(s) (0 message(s) examined)
20120522230055 Finished spamassassin training.

[] INFO: Total messages processed: 354
[] INFO: Total messages processed: 0
20120522234510 Finished spam/ham cleanup

Why did it only delete 354 of 673 messages? Does anyone have any more information about zmtrainsa --cleanup? Very curious as to why it doesn't delete all messages from the spam account.

[ewilen]

I don't think I've had the problem for a long time. Partly in response to my observation, I started being careful to "mu" (mark unread) any message I had read in the spam/ham accounts. Ultimately I just set the option in both accounts to not mark messages as read when displayed in the preview pane. I've also turned off "Double-click opens message in new window".

[dgsjeh]

I've double checked to make sure all the messages were marked as "Unread". I don't believe that was the issue.

I manually ran zmtrainsa and zmtrainsa --cleanup over and over until all the messages were gone from the account. It's almost as if the cleanup can only process so many messages at once.

A bit of a pain as we just implemented this feature and are regularly seeing 700+ messages in the spam account per day.

I agree. The multiples of '30' are interesting. I'd suggesting opening a bugzilla report and posting the bug # here.
