Resolved Plesk Email Security and Dovecot Problems

Ubuntu 22.04.4 LTS

Plesk version and microupdate number

18.0.61 #4

Hello,
I've installed and licensed Plesk Email Security.
First what happens:
Everytime a mail was moved from spam folder and the same sender writes again, the new mail goes to spam again.
In Dashboard Amavis, ClamAV, Dovecot and Postfix are green.
Sended and received HAM counting.

In logfiles are two errors:

imap: Error: TxRep: cannot run when Auto-Whitelist is enabled. Please disable it!
imap: Error: Use of uninitialized value $ENV{"PATH"} in split at /usr/lib/x86_64-linux-gnu/perl-base/File/Spec/Unix.pm line 136.

What I've done:
In /etc/mail/spamassassin/local.cf changed from "loadplugin Mail::SpamAssassin:lugin::AWL" to "loadplugin Mail::SpamAssassin:lugin::TxRep" so the first error message no longer exist.

Like some posts explains, in /etc/dovecot/dovecot.conf I insert "import_environment = $import_environment PATH". The second error perists and problem that mails are in spam folder persists.

Thank's for any idea or solution to fix ist.

What the output of cat /usr/local/psa/admin/plib/modules/email-security/resources/dovecot/es-learn-ham.sh and cat /usr/local/psa/admin/plib/modules/email-security/resources/dovecot/es-learn-spam.sh?

Thank you for reply.
es-learn-ham.sh:

#!/bin/sh

exec /usr/bin/sa-learn -u ${1} --ham

es-learn-spam.sh:

#!/bin/sh

exec /usr/bin/sa-learn -u ${1} --spam

 

[Kaspar@Plesk]

Try to add to following lines on a new line below #!/bin/sh of both these files (es-learn-ham.sh and es-learn-spam.sh)

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
export PATH

After that restart Amavis systemctl restart amavis.

 

[aschulzunna]

I've done in both files:

#!/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
export PATH
exec /usr/bin/sa-learn -u ${1} --spam

#!/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
export PATH
exec /usr/bin/sa-learn -u ${1} --ham

I've restarted amavis and dovecot. But the error persists.

[Kaspar@Plesk]

Do the files /var/qmail/popuser/es-learn-spam.sh and /var/qmail/popuser/es-learn-ham.sh exist too?

 

[aschulzunna]

Both files exists. I'ved added the two PATH Lines and restart amavis.

The error message is gone. Seems the problem is solved.

Thank you very much.

I ran into the same problem. Adding the PATH to said 2 files solved the issue, but it gets overwritten every time the plugin updates or a component is removed from Plesk. Can you make that fix permanent and ship it with the next version? Thanks!

Hello, @Cmdr . Did you update /usr/local/psa/admin/plib/modules/email-security/resources/dovecot/es-learn-ham.sh and /usr/local/psa/admin/plib/modules/email-security/resources/dovecot/es-learn-spam.sh or /var/qmail/popuser/es-learn-spam.sh and /var/qmail/popuser/es-learn-ham.sh?
I believe /usr/local/psa/admin/plib/modules/email-security/resources/dovecot/es-learn-ham.sh and /usr/local/psa/admin/plib/modules/email-security/resources/dovecot/es-learn-spam.sh shouldn't be automatically overridden.

Hello @Sebahat.hadzhi,

I edited all 4 of the files originally. The ones in /var/qmail/popuser solved the issue after a reboot of amavis, but I also modified the other 2 at the time.

The issue was gone from the logs for a few days until they appeared again. That’s when I noticed that the email security plugin was updated that morning and all files returned to its former state.

I edited the other 2 in the resources/dovecot directory and will check if it survives the next update, but I am quite sure it didn’t the last time.
