This FAQ addresses mailsend v1.17b15+
Yes. mailsend supports attachments as inline with the option `-attach "file,MIME type,i"`. Any decent mail reader (gmail does, ThunderBird does) will display the attachment as a body of the mail but it is up to the mail reader to do so. mailsend can not do anything about it.
Microsoft Outlook does not support inline content-disposition MIME header by design. Please look at the Microsoft Knowledge base article http://support.microsoft.com/kb/814111 for detail.
My observation about Outlook 2010 is, if the very first attachment is attached as inline, it shows up as embedded in the body. The rest of the attachments show up as regular attachments, no matter what kind of content-disposition is used. I have no idea what kind of logic they are using!
However mailsend v1.17b15+ has a feature to include one text or HTML file has as message body with flag -msg-body file. It also has a feature to embed images inside HTML which is supported by most mail readers including Outlook. There are some scripts for testing embedding images in HTML in the test/ directory.

mailsend v1.17b15+ has has a feature to embed images inside HTML which is supported by most mail readers including Outlook. This feature can be used to embed one complicated messsage body of the mail. Note: -msg-body file.txt can embed only one text file as message body.
Two screenshots of embedded image in HTML file are shown below:
The HTML file ../test/embed_image1.html is used to send this mail.
The HTML file ../test/embed_image2.html is used to send this mail.
To embed images in HTML one below another (without HTML file), mailsend can be run as below:
$ mailsend -sub "Embed 2 images in HTML, one below the other" \
-from mailsend@gmail.com -to mailsend@gmail.com \
-smtp smtp.gmail.com -port 587 -starttls -auth \
-user mailsend.test@gmail.com -cs ISO-8859-1 \
-embed-image "test/blue.png" \
-embed-image "test/green.png"
Note: No content ids are specified, they will be generated. The mail will like:

From v1.17b1, IPv6 is supported in all platforms. If you have IPv6 (native or through tunnel), mailsend will use IPv6 automatically if the fqdn of the SMP server resolves to an IPv6 address. Or you can just specify the IPv6 address of the SMTP server. Example:
c:\> mailsend.exe -v -info -smtp smtp.gmail.com
Connecting to SMTP server: smtp.gmail.com at Port: 25
Connection timeout: 5 secs
libmsock: using getaddrinfo

Please look at the [examples] section. Look for -ssl and -starttls and -port.
At this time it only works in linux and mac. In windows it will be needed to change code to support reading multibyte characters input from command line. Here is an example of non-ascii input in mac, mailsend 1.17b14 is running in linux:

The verbose output looks something like:

The mail in gmail looks like:

Notice smtp.gmail.com accepts raw multibyte characters. However some SMTP servers only accepts US-ASCII as data. So it is a good idea to use the option -enc base64. The verbose output will look like:

The mail will look the same in gmail.
I'll use the Firefox as an example in Windows. By default in MS Windows, Firefox will start outlook express (or nothing) to send mail when you click on a mailto: link. This behavior can be changed as follows:
- Warning:* the following instructions might be different for different version of Windows.
"C:\path\of\mailsend.exe" -smtp IP_address_of_your_smtp_server -v -d your_domain.com -f you@your_domain.com +cc +bc -v -w -t "%1"
Note: there's no need to clean mailto: tag from another program before calling mailsend.
On Unix, search on the web on how to setup external mail sender for Firefox. Again there's no need to remove mailto: tag from another script.
From v1.15a+, STARTTLS, CRAM-MD5, LOGIN and PLAIN authentication is supported. SMTP over SSL is also supported in v 1.16+. Type mailsend -ex for examples on how to use authentication.
With the option -ssl, an encrypted connection is made first and then SMTP protocol continues over the encrypted connection. For example, smtp.gmail.com supports it at port 465. With -starttls, a regular unencrypted connection is made first, then if the server supports STRTTLS, the command is issued to make the connection encrypted. For example smtp. gmail.com supports STARTTLS at port 587.
Create a text file containing the addresses and then specify the file with -list-address. The syntax of the file is as follows:
#####################################################
# File can contain addresses to send mail to.
# A line can start with To: email_address,
# Cc: email_address, BCc: email_address or
# just a valid email address.
# Any line that starts with a # or ; is considered a comment
# and is ignored.
#user@example.com
To: blah@example.com
Cc: foo@example.com
jdoe@example.com
mjane@example.com
bar@example.com
#####################################################
Make sure there is a new line at the end of the last line or the last address will be ignored. Run mailsend with -v to verify that all the addresses are used.
No.
- First of all make sure you can talk to the SMTP server ([mailsendFAQ#How_to_find_out_the_capabilities_of_a_SMTP_server?])
- Make sure the mail is accepted by the server (run mailsend with -v).
- Make sure that the SMTP server relays message to outside domain or only accepts mail from certain IP addresses (Talk to the admin).
- It is also possible the server requires authentication. Type mailsend -ex for examples on how to use authentication.
In mailsend v1.17b15+, type mailsend -show-mime-types. In older versions, look at the file mime.types
