Frequently Asked Questions

How many Mail Servers can I protect with PerfectMail?

As many as you would like.

Are there any limits to the number of domains I can protect?

No. Protect as many domains as you like.

Many of our ISP clients protect 300 to 1,000 or more domains on a single appliance. PerfectMail is extremely popular with ISPs because we do not set license restrictions on the number of domains, users users or mail servers.

How many users/e-mail addresses can I protect?

PerfectMail has no hard and fast user limits, however there are limitations based on the number of concurrent connections your license will allow. See the section on PerfectMail Features for more information.

We size our machines to meet various performance and redundancy requirements. We then make recommendations on a reasonable user population for each appliance. Our customers can, and often do exceed our recommendations by as much as 500%.

We make conservative recommendations because mail servers have no control over the volume of traffic they receive. For example, we've seen malicious activity jump by 1,000% or more even on our smallest appliances. Our appliances are sized to handle large increases in traffic without impacting the delivery of legitimate mail.

We recommend that you use our user population guidelines as a starting point and then consider higher or lower end models as your budget, redundancy requirements, etc. dictate. If you are uncertain, call us and we will help you with your selection.

Can PerfectMail handle large outbound e-mail blasts?

Yes. Outbound mail is normally delivered as soon as it is seen. If, however, you are sending a large e-mail blast, PerfectMail will queue any traffic it cannot handle immediately and will send it as soon as possible. Normally, delays (if any) are minimal.

Will PerfectMail appliances crash under excessive load?

No. PerfectMail limits the number of concurrent messages they handle to fit within its hardware capabilities. Any excess number of connections are simply told to try again later. Our approach is 100% compliant with SMTP standards and will work with any mail server. This guarantees that, while mail may be delayed during extreme loads, your appliance won't crash and mail will be delivered as soon as possible.

Is antivirus included with PerfectMail? If so, which product do you use?

PerfectMail includes the excellent Clam Antivirus product in all versions of PerfectMail. ClamAV is an excellent antivirus product that includes a fast scanning engine, very frequent updates, anti-Phishing capabilities and much more. PerfectMail appliances check for updates every 10 minutes so you are always up to date.

What does PerfectMail do with e-mails that contain viruses?

PerfectMail rejects all e-mails that contain a virus, a worm, a Phishing scam or an unwanted e-mail attachment. We do this because, try as we may, we could not think of any possible circumstance where the recipient would want to receive such a message.

PerfectMail immediately responds an SMTP reject code to the sender along with text that clearly indicates:

• That the message was rejected
• That the message contains a worm, virus or phishing threat
• Which worm, virus or phishing threat we found in the message

We also encourage PerfectMail administrators to include additional text instructing the sender to contact the recipient's help desk for assistance.

Will PerfectMail correctly filter non-English e-mails?

Yes. We have customers located in non-English locales, including Quebec Canada and Greece, who are quite happy with their PerfectMail experience. Additionally, many PerfectMail users routinely exchange e-mail with English and non-English speaking peers with no problems.

What languages does your Administrator Interface support?

At this time, our Administrator interface is available in English only. If this is an issue please contact us and we'll see if we can make changes to meet your requirements.
