Sending e-mails via workflow doesn't work

[tanea]

Hello there,

I've just purchased the Advanced Extensions Pack and tried to add some workflow rules to my EspoCRM. Everything works fine, but e-mails which are triggered in a workflow rule can't be sent.

Cronjobs are working fine, SMTP works too. E-Mails which are sent manually or even the test mail from smtp settings are delivered without problems. Only e-mails in workflows are marked in the jobs list as "failed" and the queue column shows the info "e0". I've already deleted all failed jobs and recreated the job but it doesn't work.

Whats the problem? Thanks for every help!
