## Overview sendpy is a command line email and text notification program that makes use of external and local SMTP servers to send messages.
However, sendpy is much more than that. sendpy is rich in features and use cases. For example, using this program, one may:
- Attach files to a message
- Send Unicode characters/emojis in the Subject or Body of a message
- Digitally sign a message with S/MIME or PGP encryption
- Send a notification when a long running process (LRP) has finished execution
- Delay the sending of an email until a specific time
- And more!
Help for sending an e-mail and understanding this program can be found using sendpy --help, sendpy --examples, sendpy --smtp-servers, and sendpy --gateways.
## Quick Start in 4 Easy Steps
To expedite the ability for users to send a message, here is a quick setup and example:
- Install: pip3 install sendpy or python3 -m pip install sendpy.
- Set the default configuration file to store repetitive commands (e.g., username, password): sendpy --config.
- If necessary, create an App Password or enable less secure app access with your external email service (ex. [Gmail](https://myaccount.google.com/lesssecureapps)).
- Send a basic message: sendpy --subject "Employment Opportunity" --to "connellyd2050@gmail.com" --message "Hello,nn When is a good time to talk about an open position we have for you?".
## Dependencies The following libraries are used in this program: * [OpenSSL](https://www.openssl.org/) * [GNU Privacy Guard](https://gnupg.org/) (GPG)
OpenSSL and GPG, are installed on most Linux distributions by default and may easily be installed on Windows and macOS. However, so long as a user is not signing emails (the --passphrase and --certificate flags), one may use this program without any additional installations on Windows or macOS.
## Help ``` $ sendpy --help usage: [-h] [-v] [-s SUBJECT] [-m MESSAGE] [--message-file MESSAGE_FILE] [-a ATTACHMENTS] [-t TOEMAILS] [-c CCEMAILS] [-b BCCEMAILS] [-f FROMEMAIL] [-S SMTP] [--tls] [--starttls] [-u USERNAME]

One or more To, CC or BCC e-mail addresses are required. Send text messages by using the mobile providers e-mail to SMS or MMS gateway (see the --gateways option). See examples with the --examples option.
- optional arguments:

Supports Unicode characters. -m MESSAGE, --message MESSAGE Message body. Escape sequences are expanded. Supports Unicode characters. --message-file MESSAGE_FILE Message body from a file or standard input if the filename is '-'. -a ATTACHMENTS, --attachment ATTACHMENTS Attachment filename.

Use multiple times for multiple BCC e-mail addresses. -f FROMEMAIL, --from FROMEMAIL From e-mail address -S SMTP, --smtp SMTP SMTP server. Optionally include a port with the "hostname:port" syntax. Defaults to port 465 with --ssl/--tls and port 25 otherwise. Use "localhost" if running a mail server on this device. --tls Use a secure connection with SSL/TLS (Secure Socket Layer/Transport Layer Security) --starttls Upgrade to a secure connection with StartTLS -u USERNAME, --username USERNAME SMTP server username -p PASSWORD, --password PASSWORD SMTP server password. For security, use the --config option instead for it to prompt you for the password and then store in the configuration file. - -P {5 (Lowest),4 (Low),Normal,2 (High),1 (Highest)}, --priority {5 (Lowest),4 (Low),Normal,2 (High),1 (Highest)}
- Priority. Supported priorities: "5 (Lowest)", "4 (Low)", "Normal", "2 (High)" and "1 (Highest)"
-r, --receipt Request Return Receipt -C CERT, --certificate CERT S/MIME Certificate filename for digitally signing the e-mails. It will ask you for the password the first time you run the script with this option. -k PASSPHRASE, --passphrase PASSPHRASE PGP secret key passphrase for digitally signing the e-mails with PGP/MIME. For security, use 'config' for it to prompt you for the passphrase and then store in the configuration file. -z ZIPFILE, --zip ZIPFILE Compress attachment(s) with zip -l, --language Set Content-Language. Uses value of LANG environment variable on Linux. -U, --sanitize-date Uses Coordinated Universal Time (UTC) and rounds date down to whole minute. -T TIME, --time TIME Time to delay sending of the e-mail -d, --dry-run Dry run, do not send the e-mail -n NOTIFY, --notify NOTIFY Run provided command and then send an e-mail with resulting output and exit code. -V, --verbose Verbose, show the client-server communication --config Store the --from, --smtp, --tls, --starttls, --username and --password option values in a '.sendpy.ini' configuration file as defaults for future use. It will prompt for any values that are not provided. --examples Show example usages of this script and exit --smtp-servers Show a list of the SMTP servers for common e-mail services, then exit --gateways Show a list the of SMS and MMS Gateways for common mobile providers in the United States and Canada, then exit
