Introduction

Zmail makes it easier to send and retrieve emails in python3. There's no need to manually add—server address, port, suitable protocol, and so on—Zmail will do it for you. Besides, use a python dict as a mail is also more intuitive.

Installation

Zmail only running in python3 without third-party modules required. Do not support python2.

$ pip3 install zmail

Features

• Automatic looks for server address and it's port.
• Automatic uses suitable protocol to login.
• Automatic converts a python dictionary to MIME object(with attachments).
• Automatic add mail header and local name to avoid server reject your mail.
• Easily custom your mail header.
• Support HTML as mail content.
• Only require python >= 3.5 , you can embed it in your project without other module required.

Usage

Before using it, please ensure:

• Using python3
• Open SMTP/POP3 functions in your mail (For @163.com and @gmail.com you need to set your app private password)

Then, all you need to do is just import zmail.

QuickStart

import zmail
server = zmail.server('yourmail@example.com', 'yourpassword')

# Send mail
server.send_mail('yourfriend@example.com',{'subject':'Hello!','content_text':'By zmail.'})
# Or to a list of friends.
server.send_mail(['friend1@example.com','friend2@example.com'],{'subject':'Hello!','content_text':'By zmail.'})

# Retrieve mail
latest_mail = server.get_latest()
zmail.show(latest_mail)

Demos

see zmail_demos

Examples

Verify SMTP and POP function working correctly

import zmail
server = zmail.server('yourmail@example.com’, 'yourpassword')

if server.smtp_able():
    pass
    # SMTP function.
if server.pop_able():
    pass
    # POP function.

If SMTP and POP are working correctly, the function will return True, else return Fasle.

Send your mail

import zmail
mail = {
    'subject': 'Success!',  # Anything you want.
    'content_text': 'This message from zmail!',  # Anything you want.
    'attachments': ['/Users/zyh/Documents/example.zip','/root/1.jpg'],  # Absolute path will be better.
}

server = zmail.server('yourmail@example.com‘, 'yourpassword')

server.send_mail('yourfriend@example.com', mail)

You can define sender's name by add 'from':'Boss <mymail@foo.com>' in your mail.

• To a list of recipients

server.send_mail(['yourfriend@example.com','12345@example.com'], mail)

you can also name them (use tuple, first is its name, next is its address).

server.send_mail([('Boss','yourfriend@example.com'),'12345@example.com'], mail)

• Send HTML content

mail = {
    'subject': 'Success!',  # Anything you want.
    'content_html': ['HTML CONTENT'], 
    'attachments': '/Users/zyh/Documents/example.zip',  # Absolute path will be better.
}
server.send_mail('yourfriend@example.com',mail)

or

with open('/Users/example.html','r') as f:
    content_html = f.read()
mail = {
    'subject': 'Success!',  # Anything you want.
    'content_html': content_html, 
    'attachments': '/Users/zyh/Documents/example.zip',  # Absolute path will be better.
}
server.send_mail('yourfriend@example.com',mail)

• Use carbon copy

server.send_mail(['foo@163.com','foo@126.com'],mail,cc=['bar@163.com'])

Again, you can also name them (use tuple, first is its name, next is its address).

server.send_mail(['foo@163.com','foo@126.com'],mail,cc=[('Boss','bar@163.com'),'bar@126.com'])

• Customize your server

If zmail is not working correctly, you can customize your server config yourself.

server = zmail.server('username','password',smtp_host='smtp.163.com',smtp_port=994,smtp_ssl=True,pop_host='pop.163.com',pop_port=995,pop_tls=True)

Get your mails

• Get the latest mail.

import zmail
server = zmail.server('yourmail@example.com‘, 'yourpassword')
mail = server.get_latest()

• Retrieve mail by its id.

mail = server.get_mail(2)

• Get a list of mails by its (subject,after,before,sender)

mail = server.get_mails(subject='GitHub',start_time='2018-1-1',sender='github')

In this example, if 'GitHub' in mail's subject, it will be matched, as in '[GitHub] Your password has changed'

Sender is the same way.

You can also assign the range of mails.

mail = server.get_mails(subject='GitHub',start_time='2018-1-1',sender='github',start_index=1,end_index=10)

• Get mailbox info.

mailbox_info = server.stat()

The result is a tuple of 2 integers: (message count, mailbox size).

Parse your mail

In zmail, each mail will be mapped to a python dictionary, you can access your mail by

subject = mail['subject']

Show your mail's base information, use zmail.show()

import zmail
server = zmail.server('yourmail@example.com’, 'yourpassword')
mail = server.get_latest()
zmail.show(mail)

See all contents in mail.

import zmail
server = zmail.server('yourmail@example.com’, 'yourpassword')
mail = server.get_latest()
for k,v in mail.items():
	print(k,v)

API Reference

zmail.server(username,password,smtp_host,smtp_port,smtp_ssl,smtp_tls,pop_host,pop_port,pop_ssl,pop_tls,config,timeout=60, debug=False, log=None,auto_add_from=True, auto_add_to=True)

Return MailServer instance, it implements all SMTP and POP functions.

If set any arguments which starts with pop or smtp, it will replace inner auto-generate argument (the arguments depend on the username or config you provide).

config Shortcut for use enterprise mail,if specified, enterprise mail configs will replace all inner auto-generate configs.

timeout can either be a float or int number of seconds to wait for.

debug If is True, server will open debug model and display debug information.

log The log can be None or instance of logging.logger,if is None, the zmail default logger is used, you can access it by logging.getLogger('zmail')

auto_add_to If set to True, when the key 'to' (case-insensitive) not in mail(For send), the default 'to' will automatically added to mail.

auto_add_from If set to True, when the key ' 'from' (case-insensitive) not in mail(For send), the default 'from' will automatically added to mail.

MailServer.send_mail(recipients, mail, timeout=None,auto_add_from=False, auto_add_to=False)

Return True if success.

recipients can either be str or a list of str.

mail can either be dict or CaseInsensitiveDict(Mail).mail structure see below.

timeout if is not None, it will replace server's timeout.

auto_add_from if is not None, it will replace server's auto_add_from.

auto_add_to if is not None, it will replace server's auto_add_to.

MailServer.stat()

Get mailbox status. The result is a tuple of 2 integers: (message count, mailbox size).

MailServer.get_mail(which)

Q&A

• Can not send or retrieve
  • Ensure your smtp&pop3 function is open
  • Use smtp or pop protocol settings provided by your mail server to config zmail.server, like following
  • SMTP：server = zmail.server('user','psw',smtp_host = 'xxx',smtp_port = 'yyyyy',smtp_ssl=True)
  • POP3：server = zmail.server('user','psw',pop_host = 'xxx',pop_port = 'yyyyy',pop_ssl=True)
