Email Virus and Spam Shield

A managed filter in front of your mail server. Incoming mail goes through our gateway first: spam and viruses stop there, and only clean mail gets to your server. Your mail server and your mailboxes stay where they are.

Everything that the service gives you

How the shield works: internet mail goes through the spam filter and the virus scan, clean mail gets to your mail server, spam goes to the quarantine or is blocked

Spam filtering

Each message gets a spam score. A message above your quarantine level goes to the quarantine. A message above your block level is refused. You set the two levels for each domain, or you keep our standard values.

Virus scanning

The gateway scans each message and each attachment for viruses before delivery. An infected message does not get to your mail server.

No lost mail when your server is down

If your mail server does not answer, the gateway holds the incoming mail and tries again. The mail arrives when your server is back.

Quarantine for each mailbox

Send a quarantine login link to a mailbox. The mailbox owner sees the held messages and releases the good ones. Each mailbox has a welcome list and a block list.

Proof of domain ownership

You prove that you own a domain with one DNS TXT record. Nobody else can put your domain on the service. We check the record each day, and we send you a warning mail if the record is gone.

Statistics for each domain

See the number of messages, spam messages and viruses for the last 7 days and the last 30 days.

Encrypted delivery

Select the TLS policy for the delivery to your mail server. The standard value uses encryption when your server offers it. You can make encryption mandatory.

Simple start, advanced options

Enter your domain and your mail server, and the standard values do the rest. The port, the protocol, the MX lookup and the TLS policy are in an Advanced section for the cases that need them.

Self-service client area

Add domains, change levels, see statistics and open the quarantine from your client area at any time. You see only the functions that your plan includes.

Managed by us

We operate the gateway, install its updates and keep the spam and virus definitions current. You do not install software and you do not maintain a filter server.
