MailSys.Net


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:

  1. Historically and currently we don't use the MailSys.net name in the From: field of any outbound email messages.
  2. 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.
  3. 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.

For more on SPF, we recommend you visit OpenSPF.Org.

If your IP has been banned from sending email message to us, you can try reaching out to us via our Commerco Gmail address only to explain why you need to have such an IP ban removed.

MailSys.Net does not offer email server services to the general public.
