AdvSMTP

AdvSMTP is an easy, reliable and cost-effective way to build or support SMTP applications.

AdvSMTP is the basic component used to send e-mail using Simple Mail Transfer Protocol (SMTP).

It supports multiple file attachments, multiple recipients, CCs, BCCs, plain/HTML message, US ASCII/ISO-8859-1 character sets. It does not require a SMTP server to execute. Access to the component can also be turned on or off for a specific website like all other ASPFusion components.

AdvSMTP is one of the most advanced components for sending mail messages. AdvSMTP dramatically increases the performance and dependability of your e-mail enabled applications by intercepting, sorting, queuing, and delivering outbound e-mail in the background. It can be used to create and send professional plain-text or HTML emails.

Other features are:
- It sends email messages using IP address of a specific website instead of using server IP address. Which eliminates chances of server IP address getting blocked for any spam complaints (a new feature). 
- CC and BCC. 
- Multiple attachments
- Embedded images (a new feature provided by the component). 
- Chinese and other languages support and many other features like this. 
- Along with these basic operations, it provides Upload and UploadAs operations. Upload operation allows uploading single or multiple files at a time form client browser to the server. It also allows resolving the problem of name conflicting through the property NameConflict with possible values as Error (default), Skip, OverWrite and MakeUnique. UploadAs operation allows uploading single or multiple files at a time form client browser to the server with specified name. Only few lines of code is 
- No need to specify any external SMTP server for sending mail messages. Component will lookup for recipient's SMTP server and will send mail directly to reciepient's SMTP server without using any external SMTP server (a new feature). 
- Both plain TEXT body and HTML body can be specified separately using two different methods. 
- The component can also perform logging for all sent mail messages.
The component send mail messages in two different ways.
- Blocking way, in which caller has to wait for the response from the component. 
- Non Blocking way, in which component returns control back to the caller and places a mail file in Spool folder, AdvSMTP service running at backend is then responsible to send all spooled mail messages.
