一、文件形式的郵件
代碼如下:#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import MIMEText
from email.header import Header

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msg = MIMEText('你好','text','utf-8')#中文需參數‘utf-8'，單字節字符不需要
msg['Subject'] = Header(subject, 'utf-8')

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

二、HTML形式的郵件
代碼如下:
#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import MIMEText

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msg = MIMEText('</pre>
<h1>你好</h1>
<pre>','html','utf-8')

msg['Subject'] = subject

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

三、帶圖片的HTML郵件
代碼如下:
#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'test message'

msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.
<img alt="" src="cid:image1" />
good!','html','utf-8')
msgRoot.attach(msgText)

fp = open('h://python//1.jpg', 'rb')
msgImage = MIMEImage(fp.read())
fp.close()

msgImage.add_header('Content-ID', '')
msgRoot.attach(msgImage)

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msgRoot.as_string())
smtp.quit()

四、帶附件的郵件
代碼如下:#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'test message'

#構造附件
att = MIMEText(open('h://python//1.jpg', 'rb').read(), 'base64', 'utf-8')
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="1.jpg"'
msgRoot.attach(att)

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msgRoot.as_string())
