# Emailing with Curl
|
|
||||||
|
|
||||||
`curl` is an amazing networking tool. It can even automate sending emails!
|
|
||||||
|
|
||||||
## Email just a file
|
|
||||||
|
|
||||||
For most basic emails, we can stuff the headers into the email content file
|
|
||||||
itself. Here's a basic example:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# This line writes the content to a file called email.txt.
|
|
||||||
# Usually you should use a text editor to write to a file yourself.
|
|
||||||
cat <<EMAIL > email.txt
|
|
||||||
From: Emiliko Mirror <emiliko@cs.ox.ac.uk>
|
|
||||||
To: Emiliko Mirror <emiliko@gmail.com>
|
|
||||||
Subject: Sleep triggered on $(hostname)
|
|
||||||
Date: $(date)
|
|
||||||
|
|
||||||
Dear me,
|
|
||||||
|
|
||||||
The system went to sleep! I thought I should notify my gmail account when it
|
|
||||||
happened.
|
|
||||||
|
|
||||||
cheers,
|
|
||||||
Emiliko
|
|
||||||
EMAIL
|
|
||||||
|
|
||||||
# Sends the file called `email.txt` as an email, not an email attachment.
|
|
||||||
# Note that you need to replace <my-password-here> with your gmail password.
|
|
||||||
curl --silent --ssl-reqd \
|
|
||||||
--url 'smtps://smtp.gmail.com:465' \
|
|
||||||
--user 'emiliko@cs.ox.ac.uk:<my-password-here>' \
|
|
||||||
--mail-from 'emiliko@cs.ox.ac.uk' \
|
|
||||||
--mail-rcpt 'emiliko@gmail.com' \
|
|
||||||
--upload-file email.txt
|
|
||||||
```
|
|
||||||
|
|
||||||
The `From:` - `Date:` headers at the top are very important. Gmail seems to
|
|
||||||
insert them automatically if they're missing, though other mail providers might
|
|
||||||
not, so make sure to leave them in.
|
|
||||||
|
|
||||||
If you use 2fa, you won't be able to use your account password to authenticate.
|
|
||||||
Instead, you'll need to [obtain an app
|
|
||||||
password](https://support.google.com/accounts/answer/185833?hl=en) for your
|
|
||||||
account.
|
|
||||||
|
|
||||||
## Email with attachments
|
|
||||||
|
|
||||||
We can also `CC`, `BCC` and attach files with our curl emails.
|
|
||||||
|
|
||||||
Attachments need a MIME type for the file, which is easiest obtained with the
|
|
||||||
`file` command. In this example, we also remove the headers from the email file,
|
|
||||||
opting to use the more explicit `-H` curl option.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Setup variables for attachment file. Not necessary but much cleaner
|
|
||||||
declare -r attach_file=mirrors_house.png
|
|
||||||
declare -r mime_type="$(file --mime-type "$attach_file" | sed 's/.*: //')"
|
|
||||||
|
|
||||||
# Fill a file called `email.txt` with the email content
|
|
||||||
cat <<EMAIL > email.txt
|
|
||||||
Dear classmates,
|
|
||||||
|
|
||||||
I just bought a new house! Check out the picture I attached below
|
|
||||||
|
|
||||||
OMGOMGOMG, I'm so excited!
|
|
||||||
|
|
||||||
cheers,
|
|
||||||

|
|
||||||
EMAIL
|
|
||||||
|
|
||||||
# Sends email.txt as the email content and attaches mirrors_house.png
|
|
||||||
curl --silent --ssl-reqd \
|
|
||||||
--url 'smtps://smtp.fastmail.com:465' \
|
|
||||||
--user 'kate%40mirror.house:<my-password>' \
|
|
||||||
--mail-from "kate@mirror.house" \
|
|
||||||
--mail-rcpt 'emiliko@cs.ox.ac.uk' \
|
|
||||||
--mail-rcpt 'lou@lou.me' \
|
|
||||||
--mail-rcpt 'louis@louis.me' \
|
|
||||||
-F '=(;type=multipart/mixed' \
|
|
||||||
-F "=$(cat email.txt);type=text/plain" \
|
|
||||||
-F "file=@${attach_file};filename=home.png;type=${mime_type};encoder=base64" \
|
|
||||||
-F '=)' \
|
|
||||||
-H "From: Kate Mirror <kate@mirror.house>" \
|
|
||||||
-H "Subject: Check out my new place!" \
|
|
||||||
-H "To: Emiliko Mirror <emiliko@cs.ox.ac.uk>" \
|
|
||||||
-H "CC: Lou Mirror <lou@lou.me>" \
|
|
||||||
-H "Date: $(date)"
|
|
||||||
```
|
|
||||||
|
|
||||||
Notice that for `BCC` the user isn't mentioned in `-H` at all, though you'll
|
|
||||||
still need a `--mail-rcpt` line for them.
|
|
||||||
|
|
||||||
Oddly, some mail servers seem sensitive to the filename field. My university
|
|
||||||
server would consistently bounce emails when I tried to have a filename field.
|
|
||||||
Consider removing it to use the file's actual name. In the example above, we'd
|
|
||||||
use `mirrors_house.png` instead of `home.png`.

Over the past few years, I've extenstively configured at
|
|

learnt about using MacOS, Linux, and even some BSD systems.
|
|

Along the way I documented some of the trickier aspects of

learning Unix.

These guides are mostly relevant to Linux, especially new

enthusiasts.
