Resolved - Daily cronjob "email-security/scripts/sa-train-bayes.php" fails

Since 13.03.2025 the daily cronjob "/opt/psa/admin/bin/php -dauto_prepend_file=sdk.php '/opt/psa/admin/plib/modules/email-security/scripts/sa-train-bayes.php" fails. "Plesk E-Mail Security Pro" version 1.5.12-5258 Admin error e-mail: Cron /opt/psa/admin/bin/php -dauto_prepend_file=sdk.php...

Back then, the same error occurred… however, with the current version, the following issue still persists:

Although some time has passed, the error still occurs daily when running the cron job.

In order to gather more details about the error, I can recommend running:

/opt/psa/admin/bin/php /opt/psa/admin/plib/scripts/task-async-executor.php -task-id 619

Also, checking the /var/log/cron.log file for any relevant entries.

I am afraid, cannot identify the issue by the provided errors only.

I’m still stuck with the same issue and haven’t been able to resolve it.

The daily cronjob that runs:

/opt/psa/admin/bin/php -dauto_prepend_file=sdk.php ‘/opt/psa/admin/plib/modules/email-security/scripts/sa-train-bayes.php’

keeps failing with the following error – and that’s all I get:

ERR
extension/email-security
Execution salearn has failed with exit code 1, stdout: Learned tokens from 0 message(s) (0 message(s) examined)
, stderr:

There are no additional logs or errors in /var/log/cron.log – just this message over and over again.

However, I’m 100% sure that there is plenty of spam data available for learning. Here’s an anonymized output showing the number of messages in various .Spam folders:

/var/qmail/mailnames/domain9.tld/info/Maildir/.Spam: 490

Yet, salearn reports that 0 messages were processed.

I’m starting to think this might be a permissions issue, a broken script, or even an internal bug in the module.

Any help or guidance would be greatly appreciated!

Thank you for the update. I am still unsure what could be causing the issue. I would suggest opening a ticket with Plesk support for further investigation on your server. To sign-in and open a ticket please go to:

• https://support.plesk.com

If you got your license from a reseller, your reseller is in charge of providing you with support. You can raise the inquiry with them and they can forward it to our team for further processing.

If the reseller does not provide support, here is an alternative to get support directly from Plesk:

[se2e-dev]

Am I understanding correctly that if I subscribe to the support plan, I will be charged €10 per month – and if I cancel the subscription after one month, I only pay for that month? And if I need support again in a year, I can simply re-subscribe without having to pay for the months in between or make any back payments?

 

[se2e-dev]

Additional note:

I’m unable to reproduce the issue either! On several other servers, this message does not appear, and at first glance, the configuration seems to be the same everywhere.

On those servers, the error only occurs when no emails are present, maybe once or twice a month – if at all, and definitely not daily.

As a result, we are experiencing serious spam issues!

In this context, is it possible to contact support specifically for the “Plesk Email Security” extension?

This extension was purchased directly through Plesk.

 

[Sebahat.hadzhi]

@se2e-dev , yes, you are right. You can cancel the subscription at any given moment and renew it in future if required without any outstanding payments. Considering the issue occurs only on one server indicates that the issue is likely related to the local configuration. However, that needs to be further checked on the server in question.

Yes, if you purchased the paid version of “Plesk Email Security” extension you are eligible for support using the license key of the extension (and there is no need to purchase the additional support subscription).
