How to get in body text using plain ASCII input from file

from mailozaurr.

So I just did some testing:

So it seems to work. I've not tested it with old version but after upgrading to 3.1.0 which will be used in next release (hopefully).

[PrzemyslawKlys]

Added MimeMessagePath string which allows saving the message request if we ever need to troubleshoot it

[PrzemyslawKlys]

@jstedfast Do you have any idea what would not be stripped by [MimeKit.BodyBuilder]::new() that we're using when it comes to new lines for text?

[jstedfast]

I'm thinking that this may be more likely to be an issue with passing the body as a string on the command-line? I'm not sure, though.

Keep in mind that when sending a message, message bodies are ALWAYS formatted with DOS line endings (aka CRLF).

Is the body base64 encoded? That might cause issue if the input has LF instead of CRLF, but otherwise it shouldn't be an issue.

[PrzemyslawKlys]

The -Raw switch definition:

Ignores newline characters and returns the entire contents of a file in one string with the newlines preserved. By default, newline characters in a file are used as delimiters to separate the input into an array of strings. This parameter was introduced in PowerShell 3.0.

That means it's one string with everything as is - so should be fine.

^^ It's CRLF

[jstedfast]

The BodyBuilder class just takes the TextBody and/or HtmlBody string property values and sets them as the Text property on a TextPart when it constructs the message body.

TextBody.Text calls SetText() which just does Encoding.UTF8.GetBytes(). There's no line-ending conversion.

Also note that SmtpClient.Send/Async() makes sure that line endings are CRLF format (mostly needed when running on Linux) since SMTP specifies line endings must be CRLF.

[stethos]

In order to be sure I saved the email as TXT in Thunderbird. Send-MailMessage (upper) preserves the CRLF (and adds 3 more at the end?) compared to Send-EMaillMessage (lower) which converts it to a space (0x20)

[jstedfast]

I can't think of anything in MimeKit/MailKit that would replace CRLF with a space.

Would it be possible to dump your message to a file (before sending via SMTP) so that we can see the raw message being sent before any other software has a chance to modify it?

Ideally it would use the MimeMessage.WriteTo() method.

[stethos]

I'm not a programmer and would need guidance on that.

[PrzemyslawKlys]

Basically just about here:

Mailozaurr/Public/Send-EmailMessage.ps1

Line 684 in 5aeaf9d

$SmtpClient.Timeout = $Timeout

You would need to do:

$Message.WriteTo($PathToFile)

So you either modify the module a bit, reimport it with Import-Module -Force and try again or I guess we could add some sort of debug method to Mailozaurr.

[PrzemyslawKlys]

Here's the code responsible for using BodyBuilder to build HTML/Text and then assign that Body to $Message.Body

Mailozaurr/Public/Send-EmailMessage.ps1

Lines 549 to 561 in 5aeaf9d

	$BodyBuilder = [MimeKit.BodyBuilder]::new()
	if ($HTML) {
	$BodyBuilder.HtmlBody = $HTML
	}
	if ($Text) {
	$BodyBuilder.TextBody = $Text
	}
	if ($Attachment) {
	foreach ($A in $Attachment) {
	$null = $BodyBuilder.Attachments.Add($A)
	}
	}
	$Message.Body = $BodyBuilder.ToMessageBody()

[stethos]

Looks promising - and sorry that I was not yet able to get the dump. During week time I hardly have time for such things and my plan was to deal with it on the upcoming Saturday. But now I wait for the next release.

[PrzemyslawKlys]

@stethos give new version a try

[stethos]

Sorry, still not working for me in my email client (Outlook and Thunderbird)

[PrzemyslawKlys]

what if you use the example, with the file i prepared that's on github?

[PrzemyslawKlys]

Ohhh, you're using body.... that's for HTML, you should use Text :-)

$Text = Get-Content -Path "$PSScriptRoot\Input\Test.txt" -Raw

# this is simple replacement (drag & drop to Send-MailMessage)
Send-EmailMessage -To '[email protected]' -Subject 'Test' -Text $Text -SmtpServer 'smtp.office365.com' -From '[email protected]' -Priority High -Credential $MailCredentials -UseSsl -Port 587 -Verbose

Text property takes text, body takes HTML. I am not able to distinguish between HTML and text in easy way, so I expose two options. Also you can provide both - so when HTML is disabled, text shows up AFYIK.

[stethos]

Gosh, -Text works like a charm!

Did not think about this one as I just replaced the SendMailMessage by SendEMailMessage withoug digging more deeply into every parameter.

Thank you for all your help and time you have spend on that one.
