This service release fixes a bug in EmailAgentCfg64.cpl, the 64-bit version of the EmailAgent Configuration Panel, which caused it to crash on 64-bit Windows 8 and Windows 2012.

This service release fixes a bug that may cause EmailAgent.NET to not start on older versions of Windows with the exception system.missingmethodexception showing in the Event Viewer. It also fixes a minor bug in AspEmail.NET.

The service release makes AspEmail.NET visible to COM. From now on, this native .NET component can be used in a classic ASP environment. For more information on how to use AspEmail.NET (and also AspPDF.NET) from ASP, see our KB support article PS121023186.

In service releases AspEmail 5.3.0.1 and AspEmail.NET 5.3.0.3101, support for the Advanced Encryption Standard (AES) cipher has been added to the TLS modules of both components as well as EmailAgent.NET. This enables our products to be used with SMTP servers that require AES, such as Amazon Simple Email Service (SES.)

Previous versions would generate the exception

Fatal alert received from the server: handshake_failure.

when used with Amazon SES.

A bug has been fixed in the DKIM module causing a gradual slowdown when a large number of messages is generated with a single instance of the MailSender object. This service release also fixes a minor bug in the MailLogger object.

The service release fixes a bug in the EmailAgent.NET service responsible for occasionally sending the same queued message multiple times. This bug is also responsible for the error log message "FAILURE: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."

Version 5.3 of our classic ASP and .NET mailing components features support for DomainKeys Identified Mail (DKIM), a method by which the sender digitally signs the email message to prove it really comes from the domain it claims it comes from. The recipient verifies the signature by obtaining the sender's public key from the domain's DNS records.

To send DKIM-signed messages, AspEmail and AspEmail.NET offer the new method SendCertified.

Section 5.5 of the AspEmail User Manual is dedicated to setting up DKIM infrastructure and using AspEmail to send messages equipped with DKIM signatures.

Section 3.4 of the AspEmail.NET User Manual describes the use of DKIM with AspEmail.NET.

As always, upgrading is free for registered users.

Version 5.2 of our classic ASP and .NET mailing components have the following new features:

• The new method ValidateAddressMX is capable of checking whether an email address actually exists. It performs a DNS lookup of the MX records pertaining to the email address's domain, and then contacts the corresponding SMTP server directly to verify if the address is valid.

  For more information, see Section 2.4 of the AspEmail User Manual, and Section 2.3 of the AspEmail.NET User Manual.

• AspEmail offers the new method ResetAddresses which clears the address lists but keeps the attachment, embedded image and custom header lists intact. This method has been added for additional convenience and to keep AspEmail's object model consistent with that of AspEmail.NET.
• Several minor bugs have been fixed in the EmailAgent.NET service.

A bug in EmailAgent.NET responsible for the error in the log SYSTEM: POP3 Error with host <hostname>: Index was outside the bounds of the array has been fixed.

AspEmail.NET 5.1.0.2077 accompanied by all-new EmailAgent.NET is now officially released.

EmailAgent.NET is the .NET version of EmailAgent, our message-queuing Windows service.

Compared to EmailAgent, EmailAgent.NET supports multiple queues, up to 256 simultaneous sessions, TLS and better logging. The configuration panel features a redesigned user interface.

For the detailed description of this new product, please see Chapter 4 of the .NET User Manual.

EmailAgent.NET is the .NET version of EmailAgent, our message-queuing Windows service. The new version offers many features you have been asking for.

This service release fixes several minor bugs and optimizes the message queue file generation process for EmailAgent.NET (soon to be beta-released.)

AspEmail.NET, AspEmail's native .NET counterpart, is now officially released! AspEmail.NET and AspEmail are almost entirely identical in terms of functionality, but the .NET version does not need to be registered on the web server: just place the assembly Persits.Email.dll in the /Bin directory of your application.

AspEmail.NET has its own 3-chapter User Manual and Object Reference with code samples in C# and VB.NET.

AspEmail.NET's basic functionality is free. The premium features require a registration key. The free 30-day evaluation key can be obtained here, along with the evaluation copy of the component.

This service release provides a fix for yet another minor bug in AspEmail's TLS module.

This service release provides a fix for a serious bug in the TLS module responsible for the error

Transport Layer Security Error #30 (SMTP): 503 5.5.2 Send hello first

occurring with some TLS-enabled SMTP servers. It also fixes several other bugs in the TLS and other modules.

AspEmail, a COM object, now has a native .NET counterpart! Feature-wise, AspEmail.NET is almost entirely identical to AspEmail but does not need to be registered on the web server: just place the assembly Persits.Email.dll in the /Bin directory of your application and you are good to go!

Please help us beta-test AspEmail.NET. You can download it here. We are looking forward to your feedback!

The service release contains the following fixes:

• A bug responsible for generating an error when the same instance of the MailSender object is reused to send multiple emails under TLS has been fixed. The error is:

  Transport Layer Security Error #40 (TLS): Invalid TLS version.

• When the 2nd argument to the AddAddress method contains a comma, the portion of the name after the comma is cut off. For example, the line

  Mail.AddAddress "john@company.com", "John Smith, Jr."

  would cause the recipient's name to appear simply as "John Smith". This bug has now been fixed as well.

We have added support for the Transport Layer Security (TLS) protocol to AspEmail 5.1. Now it can be used with any SMTP server requiring TLS, such as Google's smtp.gmail.com server.

TLS encrypts all traffic between the email sender and SMTP server: the authentication information (username/password), message headers, body and attachments.

To make AspEmail communicate with the SMTP server via TLS, simply set the TLS property to True:

Mail.TLS = True

As always, upgrading is free for the registered users.

The dreaded Must issue a STARTTLS command first error will haunt you no more! As of version 5.1 (now in beta) AspEmail supports the Transport Layer Security (TLS) protocol and can be used with SMTP servers that require it, including Google's popular free smtp.gmail.com server.

A problem causing the "light bulbs" on the EmailAgent Control Panel to not show on Vista, Windows 2008 and Windows 7 fixed.

Also, new installers for both the 32-bit and 64-bit versions have been built. The 64-bit installer is now fully functional -- it installs the code samples and documentation along with the executable files.

A bug causing the date information to show incorrectly in "fractional" timezones fixed.

A bug causing problems sending encrypted email with Unicode characters fixed.

The native 64-bit version of AspEmail is now officially released. Download it here.

A permanent key for the 64-bit version of AspEmail can now be purchased. For licensing purposes, AspEmail (64-bit) is a separate product. Your existing 32-bit keys will not work with the 64-bit version.

AspEmail 5.0.0.5 replaces all CR (ASCII 13) and LF (ASCII 10) characters in properties such as Subject, CharSet, Username and others with spaces to thwart "email header injection" attacks used by spammers.

In addition to this important security improvement, we also added support for Unicode characters in attachment filenames. Also, the AppendBodyFromFile method now supports text files in Unicode format.

Yet another new feature is the ability to assign a custom Message-ID to a message via the AddCustomHeader method.

AspEmail 5.0 offers a lot of new features you have been asking for, including full Unicode support and memory attachments. But most importantly, the new version comes with an all-new message queuing module which supports up to 64 simultaneous SMTP sessions, logging, CRAM-MD5 and NTLM authentication methods, automatic bounced-message handling, and much more.

For the complete list of new features, see Chapter 1 of the manual. Download AspEmail 5.0 here. Upgrades are absolutely free for registered users.

AspEmail can be used in conjunction with AspEncrypt, our powerful cryptographic component, to send signed messages, encrypted messages, and messages that are first signed and then encrypted, in the S/MIME format.

Visit www.aspencrypt.com to download your free 30-day trial copy of this component.

AspEmail is a free active server component that enables your ASP application to send email messages via any external SMTP server. The component supports multiple file attachments, multiple recipients, CCs, BCCs, and REPLY-TOs.

In addition to basic functionality available for free, AspEmail offers a number of premium features that require a registration key after a 30-day evaluation period. These features are support for message queuing, embedded images, Quoted-Printable format, multipart/alternative support and authentication. Regular file attachments are still free, of course.

This premium feature allows you to send messages in the HTML format with embedded images and backgrounds. You can even embed sounds in your messages. Here is how it's done:

...
Mail.AddEmbeddedImage "c:\dir\bk.gif", "My-Image"
Mail.Body = _
    "<HTML><BODY BACKGROUND=""cid:My-Image"">...</HTML>"
or

Mail.AddEmbeddedImage "c:\dir\ring.wav", "My-Sound"
Mail.Body = _
    "<HTML><BGSOUND SRC=""cid:My-Sound""></BGSOUND>..."

AspEmail can be used in conjunction with AspUpload, the leading file upload component from Persits Software, to send messages with file attachments over the Web, as demonstrated by our Live Demo.
