How can I send html email?

and assign your html code to BodyText property.

oSmtp.BodyText = "<html>..<body>Hello, this is a test...."

How can I add file attachments to current email?

You can use AddAttachment, AddAttachmentEx and AddAttachments method.

AddAttachment: Add file attachment with current file name.
AddAttachmentEx: Add file attachment with customized file name 
                 instead of original file name.
AddAttachments: Add all files in specified folder to current email.

Why asian language becomes ??? in email body

Firstly, you should install East Asian Languages on your machine. Secondly, 
you should set this asian language as default language for non-UNICODE program. 
If you don't want to set this asian language as your default language,
you should use CodePage property to specify current codepage of 
current email.

We suggest you use 65001 as your codepage and "utf-8" as your charset,
and all languages would be supported very well.

How to install asian languages on my machine?
Control Panel->Regional and Languages Options->Languages

How to set default language for non-UNICODE program?
Control Panel->Regional and Languages Options->Advanced.

How can I send html email with embedded pictures?

Firstly, you should create a html file on your disk, then use ImportMailEx to 
import this html to current email. This method would add all pictures in this 
html automatically as embedded attachment.

Example:
oSmtp.ImportMailEx( "c:\test.htm" )

How can I hidden some recipient's name/address in an email?

You can achieve that by adding blind copy recipient.

Example:
oSmtp.AddRecipient( "Support Team", "Support@adminsystem.net", 2 ) '2 indicates bcc.

How can I request for a receipt from recipient?

You can use AddHeader method to add a customized header. Once Outlook 
detect this header, a dialog box will appear asking for sending back a receipt.

Example:
oSmtp.AddHeader( "Disposition-Notification-To", "reply@email.com" )

Why does my email message body show as jumbled characters?

ANSMTP use base64 as default encoding arithmetic for current email, 
but it does not work perfectly in all the time. Some email clients 
do not support base64 decoding, and you need to specify another encoding 
arithmetic for current email.

Please refer to TransferEncoding property

Send Email

Why there is "Error with sending recipient"?

This is a common question in sending email. This error indicates the current
SMTP server rejected to forward email to specified recpient's email address.

How to resolve this issue?
1 .Enables your SMTP server to relay email from anonymous user. 
We DON'T recommend using this method, since your SMTP server could 
be used by other people to send bulk emails.

2. Enables your SMTP server to relay email from authorized users. You need 
to specify UserName and Password for ESMTP authentication.
Note: please make sure your SMTP server is enabled with "AUTH LOGIN" authentication.

3. Enables your SMTP server to relay email from authorized IP address. But this 
requires that your machine has a fixed ip address.

4. Send email by DNS lookup. Click here to learn more details.

5. Send email by pickup path of IIS SMTP Service. Click here to learn more details.

Why there is "Error with sending sender"?

This error indicates the sender email address is not valid. You should
assign a valid email address to FromAddr property.

Why there is "Error with DNS lookup"?

This error indicates the current recipient email address is invalid so 
that ANSMTP can't retrieve the local SMTP server of this email address.

How can I get a free SMTP server to send email?

We suggest you use IIS SMTP Service to send email. Click here for more detail.

How can I send email without SMTP server?

You can send email via DNS lookup, this features doesn't require a smtp server. 
Click here for more detail.

How can I send mass emails with high performance?

MassSender object is your right choice. It can send email in a smart threading-pool
with high performance. Please visit developer center to learn more details.

How can I send bulk emails in ASP/ASP.NET with mail queuing?

There are several ways to enable your asp/asp.net applictaion to send email 
with mail queuing. Please visit developer center to learn more details.

How can I handle bounced email/delivery failure?

If you send email via dns lookup, ansmtp gives the result directly by 
GetLastError method(synchronous mode) or OnError event(asynchronous mode).

If you send email via specified smtp server, then delivery failure report should be
sent to the email address specified in FromAddr property by your smtp server. In 
this case, you can use anpop to check this pop3 account to get the detail.

S/MIME

Why I can't create CAPICOM objects?
