We cannot say much about this problem, unless we get some more information:
What is your configuration? Provide the output of dovecot -n.
Is it reproducible somehow?
What is the Sieve script you see this behavior for? Or does it happen for all users?
Is there a specific kind of incoming message that gets discarded all the time?
Is there any error or other message in the logs that may explain this behavior?
Regards,
Stephan.

- Is it reproducible somehow?
this is rare but does occur from time to time. I do not know how to reproduce
- What is the Sieve script you see this behavior for? Or does ithappen for all users?
i use a simple script sieve of this style ~]$ cat .dovecot.sieve require ["fileinto", "mailbox" ,"reject", "regex", "variables","envelope", "subaddress"]; # rule:[perl] if anyof (header :contains "Return-Path" "perl.apache.org", header :contains "Return-Path" "perl",header :contains "Return-Path" "groups.yahoo.com", header :contains "Return-Path" "jaos", header :contains "Return-Path" "dkimproxy", header :contains "Return-Path" "mongueurs", header :contains "Return-Path" "pep", header :contains "Subject" "dkimproxy", header :contains "To" "perl@mongueurs.net", header :contains "To" "pep@perl.org", header :contains "To" "perlwebmail-devel@jaos.org", header :contains "Return-Path" "jlong@messiah.edu", header :contains "To" "dkimproxy-users@lists.sourceforge.net", header :contains "Cc" "dkimproxy-users@lists.sourceforge.net",header :contains "Return-Path" "templates-bounces@template-toolkit.org",header :contains "Return-Path" "pm.org") { fileinto :create "INBOX.perl"; stop; }
- Is there a specific kind of incoming message that gets discardedall the time?
no there is no particular type of message just some messages
- Is there any error or other message in the logs that may explain this behavior?

Ok, so you are using multiscript with sieve_before.

This is really strange. Even though your script does not contain a discard command, the message is discarded through an explicit discard action. I do notice that you are using the multiscript feature using sieve_before and I expect that our problem is there. Notice that the same message is discarded in an identical manner for two different users (root and fakessh). What does /var/sieve-scripts/roundcube.sieve contain?
Also, it can be helpful to enable mail_debug to get more info on what scripts are being executed and which script actually triggers the discard action.
Regards,
Stephan.

I just set up mail_debug = yes I expect the next reject in order to give you more information
