Dynamics CRM 2013 Configuring SMTP profiles on port 25

If you just process outgoing email in Dynamics CRM 2013 then you no longer need Email router to do this. Dynamics CRM 2013 introduces Exchange synchronization but also POP3 and SMTP profiles which you can leverage as an SMTP gateway. In this article I'm focusing on SMTP profiles and how to make it work on SMTP port 25.

Why SSL does not matter in this case? it's because we are not storing any credentials we are using Anonymous authentication to relay email.

1. Enabling Port 25
Before we start configuring the SMTP profile in CRM you need to run the following SQL commands to disable SSL for SMTP profiles:

SQL Update

Update DeploymentProperties set BitColumn = 1 where columnname = 'AllowCredentialsEntryViaInsecureChannels'

Update DeploymentProperties set BitColumn = 1 where columnname = 'ECAllowNonSSLEmail'

Via Power Shell

• To allow the use of credentials when not using SSL, run the following commands.

$itemSetting = new-object 'System.Collections.Generic.KeyValuePair[String,Object]' ("AllowCredentialsEntryViaInsecureChannels",1)$configEntity= new-object "Microsoft.Xrm.Sdk.Deployment.ConfigurationEntity"$configEntity.LogicalName = "Deployment"$configEntity.Attributes=new-object "Microsoft.Xrm.Sdk.Deployment.AttributeCollection"$configEntity.Attributes.Add($itemSetting)set-CrmAdvancedSetting -Entity $configEntity

• To allow the use of connections to servers that do not use SSL, run the following commands.

$itemSetting = new-object 'System.Collections.Generic.KeyValuePair[String,Object]' ("ECAllowNonSSLEmail",1)$configEntity= new-object "Microsoft.Xrm.Sdk.Deployment.ConfigurationEntity"$configEntity.LogicalName = "Deployment"$configEntity.Attributes=new-object "Microsoft.Xrm.Sdk.Deployment.AttributeCollection"$configEntity.Attributes.Add($itemSetting)set-CrmAdvancedSetting -Entity $configEntity

After the SQL update do an iisreset and refresh the page, then Navigate to Settings > Email Configuration


2. Create The SMTP profle
Click New and select POP3-SMTP Profile

Choose a name and type the FQDN for the email server, if you don't want to use pop3 you can leave it empty:

The Authentication options should be as follows:

Click Advanced and select No on the option that says Use SSL for Outgoing connection

3. Configure User Profiles 
The next step is configuring the user mailbox properties; we want to set the mailbox to use the SMTP profile and disable incoming mail.

4. Global Settings
If you want these settings applied globally you can use the global Settings under Settings > Administration > System Settings

Email tab:
