When an email is sent to a Parallels Plesk Panel server with an apostrophe in the “From” address (such as abc’firstname.lastname@example.org), an error is registered in the mail handler. When such an email is received, an error similar to the following may appear in the mail handler logs:
Unable to get sender handlers from the database
When this error occurs, emails can fail to be delivered to the recipient.
The cause of this error is a functionality bug in Parallels Plesk Panel. There are no security concerns or possibilities of compromised data from this bug.
Parallels is currently working on patches to resolve this issue. Once available, this Knowledge Base article will be updated with these patches.
