Hi,

I hope this can help you. Can you let us know the log of the SMTP server
in 127.0.0.1(that's what you tested with linux console, right?) ? 

Following code is one of my method for sending email messages, and I also cannot
find any meaningful differences between your code and mine.

sendMail
	| client msg m sub mm recvs |
	client _ SMTPClient openOnHostNamed: smtpServer.
	userID isEmptyOrNil 
		ifFalse: [ client user: userID.
				 password isEmptyOrNil
					ifTrue: [ client password: '' ]
					ifFalse: [ client password: password ]].
	m _ MimeConverter forEncoding: 'base64'.
	"sub _ (m mimeEncode: (subject convertToWithConverter: (UTF8TextConverter new)) readStream)
		contents."
	sub _ (m mimeEncode: subject readStream) contents.
	sub _ sub copyReplaceAll: String cr with: ''.
	"mm _ (m mimeEncode: (messageBody convertToWithConverter: (UTF8TextConverter new))
		readStream) contents."
	mm _ (m mimeEncode: messageBody readStream) contents.
	recvs _ (receivers inject: '' into: [ :s :e | s size = 0 ifTrue: [ s _ s, e ] ifFalse: [ s _ s, ', ', e ]]).
	msg _ 
		'MIME-Version: 1.0', String cr,
		'Content-Type: text/html; charset=UTF-8', String cr,
		'Content-Transfer-Encoding: base64', String cr,
		'X-Priority: 3', String cr,
		'X-Mailer: NXT', String cr,
		'Sender: ', replyTo, String cr,
		'Subject: ', '=?UTF-8?B?', sub, '?=', String cr,
		'To: ', recvs, String cr, String cr,
		mm.
	[ 
		client login.
		client 
			mailFrom: replyTo
			to: receivers asArray
			"text: (msg convertToWithConverter: (UTF8TextConverter new))."
			text: msg.
	 client quit ] ensure: [ client close ].

  Hi: I am trying to send an email from Squeak. I have ubuntu and postfix smtp server running in my local machine. I know postfix is running OK. I could do successfully the following test from a linux console:<br><br>220 Servidor ESMTP<br>
