Using curl to send email

问题:

How can I use the curl command line program to send an email from a gmail account?

I have tried the following:

curl -n --ssl-reqd --mail-from "<sender@gmail.com>" --mail-rcpt "<receiver@server.tld>" --url smtps://smtp.gmail.com:465 -T file.txt

With file.txt being the email's contents, however, when I run this command I get the following error:

curl: (67) Access denied: 530

Is it possible to send an email from an account that is hosted by a personal server, still using curl? Does that make the authentication process easier?

回答1:

curl --url 'smtps://smtp.gmail.com:465' --ssl-reqd \
  --mail-from 'username@gmail.com' --mail-rcpt 'john@example.com' \
  --upload-file mail.txt --user 'username@gmail.com:password' --insecure

mail.txt file contents:

From: "User Name" <username@gmail.com>
To: "John Smith" <john@example.com>
Subject: This is a test

Hi John,
I’m sending this mail with curl thru my gmail account.
Bye!

Additional info:

  1. I’m using curl version 7.21.6 with SSL support.

  2. The --insecure switch allows curl to perform "insecure" SSL connections and transfers. See this online resource this online resource for further details.

  3. It’s considered a bad security practice to pass account credentials thru command line arguments. The above example is for demo purpose only.

  4. You must turn on access for less secure apps.
