This domain supports email services for domains held by The Commerce Company.
If you are here because you think MailSys.Net servers sent you a message you
didn't want (and we actually most likely didn't send), we
have a couple of thoughts for you to consider:
Historically and currently we don't use the MailSys.net name in the
From: field of any outbound email messages.
Our MailSys.Net domain publishes an SPF DNS TXT record to allow your own
email servers to discover our legitimate servers authorized to send email
under the MailSys.Net name.
Any domain sending via MailSys.net will have a DNS SPF record which points to
MailSys.Net which you can check (and really which your email server should have
checked) and will know which servers can send email on behalf of the domain.
If you are here because the From: field in one or more of your messages
included MailSys.Net, please check with your IT folks about implementing
SPF in your own eMail servers.
When implemented properly, your receiving SPF aware email server would
have absolutely known not to accept mail from MailSys.Net via any other IPs
than those we have published in our SPF record, meaning your day and
ours would not have been interrupted by the spammers.
