Send Mail with File Attachment

How do I send a file as an email attachment using Linux command line?

None of the mutt ones worked for me. It was thinking the email address was part of the attachment. Had to do:

echo "This is the message body" | mutt -a "/path/to/file.to.attach" -s "subject of message" -- recipient@domain.example

How to send email attachments?

Here's another:

import smtplib
from os.path import basename
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.utils import COMMASPACE, formatdate

def send_mail(send_from, send_to, subject, text, files=None,
              server="127.0.0.1"):
    assert isinstance(send_to, list)

    msg = MIMEMultipart()
    msg['From'] = send_from
    msg['To'] = COMMASPACE.join(send_to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject

    msg.attach(MIMEText(text))

    for f in files or []:
        with open(f, "rb") as fil:
            part = MIMEApplication(
                fil.read(),
                Name=basename(f)
            )
        # After the file is closed
        part['Content-Disposition'] = 'attachment; filename="%s"' % basename(f)
        msg.attach(part)

    smtp = smtplib.SMTP(server)
    smtp.sendmail(send_from, send_to, msg.as_string())
    smtp.close()

It's much the same as the first example... But it should be easier to drop in.

Send attachments with PHP Mail()?

I agree with @MihaiIorga in the comments – use the PHPMailer script. You sound like you're rejecting it because you want the easier option. Trust me, PHPMailer is the easier option by a very large margin compared to trying to do it yourself with PHP's built-in mail() function. PHP's mail() function really isn't very good.

To use PHPMailer:

• Download the PHPMailer script from here: http://github.com/PHPMailer/PHPMailer
• Extract the archive and copy the script's folder to a convenient place in your project.
• Include the main script file -- require_once('path/to/file/class.phpmailer.php');

Now, sending emails with attachments goes from being insanely difficult to incredibly easy:

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

$email = new PHPMailer();
$email->SetFrom('you@example.com', 'Your Name'); //Name is optional
$email->Subject   = 'Message Subject';
$email->Body      = $bodytext;
$email->AddAddress( 'destinationaddress@example.com' );

$file_to_attach = 'PATH_OF_YOUR_FILE_HERE';

$email->AddAttachment( $file_to_attach , 'NameOfFile.pdf' );

return $email->Send();

It's just that one line $email->AddAttachment(); -- you couldn't ask for any easier.

If you do it with PHP's mail() function, you'll be writing stacks of code, and you'll probably have lots of really difficult to find bugs.

Send mail with file attachment

It seems that attachment in mailto: URLs are not supported on macOS (not always at least...details seems sketchy dependent on where you look on the internet :))

What you can use instead I found out from this blog post, is an instance of NSSharingService documented here

Here is an example demonstrating how to use it.

And in your case you could do something like:

let email = "your email here"
let path = "/Users/myname/Desktop/report.txt"
let fileURL = URL(fileURLWithPath: path)

let sharingService = NSSharingService(named: NSSharingServiceNameComposeEmail)
sharingService?.recipients = [email] //could be more than one
sharingService?.subject = "subject"
let items: [Any] = ["see attachment", fileURL] //the interesting part, here you add body text as well as URL for the document you'd like to share

sharingService?.perform(withItems: items)

Update

So @Spire mentioned in a comment below that this won't attach a file.

It seems there is a gotcha to be aware of.

For this to work you need to look into your App Capabilities.

You can either:

• disable App Sandbox
• enable read access for the folders from where you would like to fetch content.

I've attached a couple of screenshots.

Here is how this looks if I have disabled App Sandbox under Capabilities

And here is an image where I have enabled App Sandbox and allowed my app to read content in my Downloads folder

If I do the above, I can access my file called document.txt, located in my Downloads folder, using this URL

let path = "/Users/thatsme/Downloads/document.txt"
let fileURL = URL(fileURLWithPath: path)

And attach that to a mail

Hope that helps you.

How to close the file after sending emails with an attachment?

Just like you open a file with open() you need to close it with close()
As in attachment.close(). Or, even better, use context manager:

with open(row["filepath"], "rb") as attachment:
   # Code that uses attachment file goes here
# Code that no longer uses that file goes here

Context managers guarantee that file will be closed outside of the with block.
