Its not quite clear from the logs about the root cause. it seems like email validation issue but, Can you enable these debug logs and get the full stack trace of the error?

log4j.logger.org.alfresco.repo.action.executer.MailActionExecuter=debug
log4j.logger.org.alfresco.repo.transaction.RetryingTransactionHelper=debug

The setting mail.validate.addresses in the alfresco-global.properties controls whether email addresses will be validated via the Apache Commons Email Validator utility. For custom TLDs not defined by default in the Domain Validator utility (called by the Email Validator), this would be the source of the error.
