Remarks

EASendMail Service is a light and fast email delivery service which works with EASendMail SMTP .Net Component / ANSMTP SMTP Component to enable your application to send mass emails in background service. Along with its ability to picking recipients from database in background and sending email in specified datetime, it eases your task in developing featured email application such as newsletter application. We strongly recommend you to use EASendMail Service with your ASP/Web Application. To learn more detail about SendMailToQueue method, please refer to Work with EASendMail Service (Email Queuing) section.

If your appliation want to send email to EASendMail Service on local or remote server, you should use this method.

Before you use PostToRemoteQueue method, you should deploy EASendMail Service Agent on the remote server.

Open IIS Manager on your remote server.
Choose default website, right click -> Add Application ->
Input eaagent as application alias and set physical path to "EASendMail Service installation path\EAAgent" (.NET 2.0 or later version) or EAAgent40 (.NET 4.0).
Now you have installed EASendMail Service Agent successfully.
You can set user access permission for this application in IIS Manager -> Authentication (optional, if you set user permission, you should assign valid user/password in PostToRemoteQueue method).
