SRV record for submission (587)
When Enable mail autodiscover AND Enable SMTP service on port 587 on all IP addresses are enabled within the Server-Wide Mail Settings, it'd be nice if Plesk would also create an according SRV record.
_submission._tcp IN SRV 0 1 587 mail.domain.tld.
Currently, Plesk only creates smtps with 465.
