In the admin interface I got pointed to mail processing errors, which are in fact two entries of a “Job exception: 451 Error while writing spool file”.

Do you have some more infos about this for me? With ~4000 mails sent yesterday, these 2 errors seem to be not that serious. Nevertheless, I ask myself for possible reasons. Out of disk space? At least locally that is unlikely. What else?

Thanks,  
Dirk

This is the log entry:

That error is being reported by the app as coming from your mail server. Whatever you’re relaying mail to had a temporary problem, which the e-mail sending worker should have detected and retried the e-mail sending later.
