We already provide free SSL connections to end users who wish to use SSL to access webmail or configure their email software. Please see configure an email client for details. You will not need to maintain or pay for the SSL certificate if you use our mail servers.
If, however, you would like for your customers to access SSL through a custom subdomain (e.g. mail.acmeinc.biz), we can install the SSL certificate for you. The initial installation fee is $100. You will also need to purchase and renew the SSL certificate as well. The fee to install a renewed certificate is $100.
To get started, make sure that the domain (e.g. acmeinc.biz) exists under the "Email" section in the control panel. Please also map your subdomain (e.g. mail.acmeinc.biz) to our our email server.
We will also need the following information:.
Subdomain to use (e.g. mail.acmeinc.biz):
State (full state name):
Locality (full city name):
Organization (full legal company or personal name):
[Optional] Organizational Unit (branch of organization):
Please email us the information. We will then generate a CSR for you that can be used to purchase a SSL certificate. The certificate can be purchased through the OpenSRS control panel or from other providers. When ordering the certificate, please choose Apache or Apache+modSSL as the server type. We support 2048 bit encryption.
Certificate installation and renewal takes about one week so please allow ample time.
You and your customer's MX records should be mapped to our hostedemail.com email server. Unless you have a SAN covering their subdomain, their mail DNS record should be left blank or permanently redirected to your subdomain (e.g. mail.acmeinc.biz). They should be using your company's branded subdomain for the email service, not their own.
Frequently Asked Questions
Can a reseller account have multiple custom SSL subdomains?
Yes, though it is not recommended. Each reseller should ideally have one subdomain, such as mail.acmeinc.biz, where all customers sign in. One single subdomain is good for brand reinforcement as well as easier troubleshooting for your support staff.
However, if you would still like to have multiple subdomains, you can provide us with one cert per subdomain or a SAN certificate containing all the subdomains you would like to have, such as
Some certificate vendors allow up to 100 SANs per certificate. For this setup, however, please keep in mind the following caveats:
- If you add/remove common names from your cert and need the cert reinstalled, the installation fee of $100 applies per reinstall.
- If the end user checks the content of the cert, they will see all the SANs listed on the cert.
- Since an IP is assigned to the cert, the reverse DNS lookup of that IP will be assigned to the main subdomain on the cert. Please let us know if you prefer to have another subdomain for the IP in the PTR record.
The CNAME for these common names will need to be mapped to the right cluster in order to prevent browser certificate errors.
If I already have a certificate containing the SAN I want to use, can I provide that for installation?
Yes. Keep in mind that if you have to re-issue the cert for any reason and the cert has to be reinstalled on our end, the installation fee of $100 applies per reinstall. Please contact OpenSRS Support so we can obtain the private key from you in a secure manner.
If I purchase a wildcard certificate, can I have unlimited subdomain email logins?
Yes. If you provide a certificate such as *.acmeinc.biz, you can have unlimited number of subdomains, such as
Can the certificate be installed on a root domain?
Yes. A certificate can be installed on a root domain, such as
For such an installation, please request a CSR from us and purchase the certificate with the CSR. After the installation, we will reply back with an IP address so that the root domain can be mapped to the IP.
