zMailCloud uses an integrated, advanced anti-virus and anti-spam system called AS/AV ("asav") to control in-bound spam and virii. This system allows you the user to control settings for your mailbox through a web control panel, and allows you the domain admin to control settings for your entire domain.
Based on experience, typical anti-virus success is greater than 99.9%. For these results, please read on for best practices to configure your advanced anti-spam and anti-virus settings.
TROUBLESHOOTING? See the very bottom of this article for quick-win suggestions.
Logging InTo personalize your anti-spam and anti-virus filter settings, login securely using your web browser: https://asav.zmailcloud.com
Enter your full e-mail address and password to enter the website and manage your preferences, as below, substituting "email@example.com" with your email address and domain.
White ListYou can add email addresses or domains to this list that you never want marked as spam. Please note that emails sent to you from these email addresses or domains will still be scanned for viruses and dangerous file attachments but even if they contain them they will not be marked as spam (unless you check the headers, per tech note 2, below).
In the add to whitelist field, add domains (such as customer.com) and e-mail addresses (firstname.lastname@example.org) to your white list to always receive mail from these senders. Click the 'Add' button to confirm your entry. The 'Delete Selected' button below allows you to remove entries.
A domain entered by itself acts as a wildcard for every related email address, host and subdomain. In other words, adding a domain name by itself will whitelist everything from that domain name.
For example, enter only "*@abc.com" to whitelist mail from email@example.com, firstname.lastname@example.org and email@example.com. Enter *@*.abc.com" to whitelist everything from the subdomains or hosts www.abc.com, ftp.abc.com, mail1.abc.com and mail.abc.com, as well as abc.com."
TECH NOTE 2: for white and blacklisting, asav ignores the "From:" and the "Reply-to:" information, and instead examines the email header envelope and uses the value that will go into Return-Path, but before the Return-Path header is created. For instance, to whitelist email from the sender of the following message header, firstname.lastname@example.org, and all other mail from myclient.com, you must whitelist "sender-mail.net", and not myclient.com:

General Spam Preferences
Scroll to the bottom for quarantine details:
Login to your webmail account at: https://mail.01.com/
Locate a message to mark as Spam:
Select message and mark as 'Junk':
After clicking on Junk, the message will be moved to your Junk Mail folder and be identified as Junk by the ASAV system, improving future filtering.
Mark Ham in your Junk folder as 'Not Junk'. Note that "Ham" is mail incorrectly identified as spam, or possibly spam ("false positives").
- Your own domain name. Unless otherwise instructed, do not white list your own domain name. This will cause the system to accept anything from your own domain, and spammers may send from you to you, or from an invented name in your domain to you.
- Alias domain names. You must set preferences and white/black lists for your alias domains, too, if you're using them. Login to asav using your mailbox name and the alias domain, and set your preferences, too.
- Identifying the right domain. Sometimes your sender is using an email server at a different domain. For example: you. The domain of your mail server is 01.com, even though that's not your domain name. Your sender may be in the same situation, so even though the sender's domain is yourclient.com, you may have to whitelist yourclientsemailhostingprovider.com to whitelist email from your client's domain. You can verify you've whitelisted a domain or email address successfully by examining the email header information of an email from that sender, and look for the line: "X-Fsl-Mailscanner-Spamcheck: not spam (whitelisted)"
- Mailwatch: reading envelope information in mail headers. Determine which domain to whitelist or blacklist.
