Note: Each account can store up to 15 unique SMTP Credentials
Almost all third party SMTP clients, Servers, CMSs and Plugins will use these settings to connect and relay mail through your Elastic Email Account. We don't know of any software that supports SMTP connections that do not work with Elastic Email but there is a list of CMSs and Plugins that are designed to work specifically with our platform.
Create SMTP Credentials
New accounts do not have any SMTP Credentials. Click this button to create a new one.
Username:
Your Elastic Email Account SMTP Username defaults to your Elastic Email Account email address that you use to log in. You can use another email address, but it has to be unique across the entire system - just as with account email addresses. Here you can also set IP access restriction.
After clicking the Create button, a pop up will appear with your newly created SMTP Credential details.
IP access restriction:
When you create or edit an SMTP Credential, you can expand "Set access restriction (optional)" and limit the IP addresses that can connect with that credential. Enter one IP address or range, or several separated by commas. The supported formats are:
a single IPv4 address, for example 192.0.2.10
an IP range, for example 192.0.2.10-192.0.2.20
a CIDR block, for example 192.0.2.0/24
IPv6 addresses.
If you leave the field empty, the credential can be used from any IP address and shows "Restricted access: Disabled". This only means that no IP restriction is set. The SMTP Credential is valid and active, and you can use it to send email.
Password:
A unique password for your SMTP connection. Copy it and save it in a safe place. Once you close this window you will not be able to retrieve it. After this step, our system will obfuscate it except for the last 5 digits for your security reasons.
Server:
Port:
We support the following connection ports:
25, 2525, 587, 465
We support TLS 1.2 and SSL connections. Make sure the connection port you are using is open on your own server.
Using Postfix? If you are configuring postfix as a local relay, make sure you include the following three lines in your postfix configuration
