EVO Mail Server settings

    1. Status – An overview of mail services, DNS settings, and hardware settings:

      • Mail services status -Turning on or off EVO mail service:status
        • License status – License activation status: licensee or trial expiration date.
        • System service – Click on START to start service or click on STOP to turn off.
        • SMTP service – Current SMTP port being used: 25, 587 or 465.
        • POP3 service – Current POP3 port being used: 110 or 995.
        • IMAP service – Current IMAP port being used: 143 or 993.
      • Network setting status – Current network and DNS status of your mail server:status_network
        • IP address – All detected IP addresses assigned to EVO Mail Server computer host.
        • All domain names – Local host name and all domain names for which EVO is hosting mail services.
        • Reverse DNS – Server host name to which your public IP is reversely resolved and it is usually the MX record value.
          Note: Like screenshot, major mail service providers, such as gmx.com and 1and1.com, start to reject mails if the reserve resolution value s different than your domain.
        • IP Reputation – IP reputation check on mail server host’s public IP address.
        • MX record – DNS record with computer host name(s) handling mail exchange job for primary domain.
        • SPF record – DNS record with authorized mail server(s) handling mail exchange job for primary domain. (What is SPF?)
        • SRV record – One or more DNS records enables mail clients to auto-discover mail server’s parameters for auto-configuration. (What is SRV?)
        • DKIM record – The DKIM support attaches a dedicated signature signed by your domain’s private key. Recipient mail server will try to pair it up with the DKIM public key given in sender mail server’s DNS hosting service. If they match, then we can assume this e-mail came from a legit mail server belonged to sender’s domain.
          • When it is not configured or configured incorrectly, a warning message will appear as below:
          • Now, click on the Solution button to the right. There will pop up a notepad window showing primary domain’s public key that is to be implemented in DKIM record in DNS hosting service.
          • Use COPY+PASTE hotkey to copy the full string and transfer it to DKIM TXT record in DNS hosting service. Basically, two parts are required to be pasted: (Zoneedit is used as an example)
            • Host: A fixed value of evoms._domainkey. If your service provide’s TXT format requires entering a Selector , thenenter evoms instead.
            • Parameter or value: Paste the full string we mentioned previously.
          • Once completed, restart EVO Mail Server’s UI. If configured correctly, then DKIM line will appear as below:
          • Check if recippient mail server passes DKIM from sender mail server. Let’s send an e-mail to Gmail. Then, log on Gmail and open the incoming e-mail with DKIM in it. Click on 3-dots button at top-right and select Show original. The DKIM line will show ‘PASS’.
          • NOTE 1: If we need to add DKIM to secondary and additional domains, let say it’s domain2, then go to c:\ProgramData\EvoMailServer\CONFIGS\CERTSTORE\ and open domain2._domainkey. Perform COPY+PASTE and proceed step 3 and so on.NOTE 2: Recently, DKIM and SPF have increasingly caught attention of Gmail, Yahoo,Outlook.com and other major mail service providers. Once they are implemented, DMARC record can also be implemented to reduce the chance of e-mails from your mail server being recognized a spam mail can be smaller.NOTE 3: DMARC – Following implementation of SPF and DKIM, DMARC (Domain-based Message Authentication Reporting and Comformance) can be configured. DMARC enables sender mail server to suggest recipient mail serer how to deal with e-mails suspicious of being spam mails. In return, recipient mail server will periodically provide corresponding statistic report to sender mail server.
            The following steps will guide you on how to configure DKIM feature:

            • Log on your DNS hosting service.
            • Add a TXT record.
            • For Host, enter _DMARC.
            • For parameter, it varies how you like to define the rule and here is an example: “v=DMARC1; p=none; rua=mailto:[email protected]”. Refer to DMARC official website for more detail.
            • Save settings and wait for DMARC record to be effective. Then, check the record via MX Toolbox:
        • Spamhaus ZEN – Anti-spam service from Spamhaus if mails are sent from spam source.
        • SSL Cert. & Key – Checks if current installed SSL certificate matches primary domain’s common name (CN).
      • Server setting status – Hardware and software info on mail server:status_server_setting
        • Server information – Server host name,  operating system and CPU type (Recommended hardware spec).
        • Windows Firewall – Port opening status on Windows Firewall. Click on the circle arrows to the right to start detecting current Windows Firewall port status.  (How to open a port?)
        • NAT (Internet Sharing) – Port mapping status on NAT. Click on the circle arrows to the right to start detecting current NAT port status. (Refer to your NAT’s user manual)
        • Mail Data Folder – Data storage location for mail data and mail server configuration files. Click on the circle arrows to the right to browse folders and move all mail data to the new location.

        • Setting Mode – Click on Simple or Advanced button to further configure EVO Mail Server.
        • Primary Domain – Primary domain that EVO Mail Server is hosting for.  EVO Mail Server will check the domain’s DNS configurations as well as certificate’s common name (CN). Check result will reflect on Network section of Status tab. Tip: This checkup also works on your additional domain(s) when you replace primary domain with the additional domain(s) one at a time.
        • Additional Domain(s) – Additional domain(s) that EVO Mail Server is hosting for. EVO will check the domains’ DNS configurations as well as certificate’s common name (CN). Regarding IP reverse resolution for additional domain(s), as long as server IP’s reverse resolution value does not contain keywords such as PPPoE, dynamic, dialup, or dial-up, mails delivered from additional domain(s) should not be rejected by recipient mail server due to IP reverse resolution issue.
        • Act as Backup MX for – EVO Mail Server is able to play as a contingency backup server to temporarily receive e-mails for domains other than the ones hosted by EVO Mail Server. Once the domain’s primary mail server is back online, EVO Mail Server will relay all mails received during downtime back to the primary mail server. Before doing so, add one A record and one MX record in that domain’s DNS configuration.
        • Connection Timeout – An integer value between 120 to 1800 and counting in seconds. When exceeding this defined time frame, if there is not any activity in a session, then EVO Mail Server will disconnect from it.

        • Archive folder structure – Mail archive folder structure can be sorted either by Date or Domain.
          • Reminder:
            • If by Date, archive operator or auditor can view all domains regardlessly.
            • If by Domain, then he is only privileged to view the domain where he belongs to under <EvoMailServer folder>/HOSTS/DEFAULT/ ARCHIVE.
            • Or, there is a more restricted setting by narrowing privilege down to the department level where he belongs.
          • Please follow the rules below for regulating archive access privileges along with this screenshot:

        • Normally, a word can be expressed in different combinations of upper case and lower case. For example, spam keyword like porn can look like Porn, pOrn, PORN, porn and many others. If we were to compare all possibilities one by one, then it will be a very inefficient way. If we use Regular Expression, then only one short line is required: {[pP][oO][rR][nN]}.
        • For a complete reference on RegEx, please visit Microsoft’s website of Regular Expression Language – Quick Reference.
        • To utilize RegEx, select RegEx matching in Expression or operand pull-down list. Then, enter RegEx string in Compared value space.
