在CentOS上配置Python郵件發送,通常需要以下幾個步驟:
安裝必要的軟件包:
smtplib
(Python標準庫自帶)和email
(Python標準庫自帶)。配置郵件傳輸代理:
編寫Python腳本:
smtplib
和email
庫編寫郵件發送腳本。以下是詳細步驟:
首先,確保你的CentOS系統已經安裝了Python。如果沒有安裝,可以使用以下命令安裝:
sudo yum install python3
sudo yum install postfix
在安裝過程中,選擇“Internet Site”配置類型,并設置系統郵件名稱。
編輯Postfix的主配置文件/etc/postfix/main.cf
,添加或修改以下內容:
myhostname = your_hostname.example.com
mydomain = example.com
myorigin = $mydomain
inet_interfaces = all
inet_protocols = ipv4
mydestination = $myhostname, localhost.$mydomain, $mydomain
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
然后重啟Postfix服務:
sudo systemctl restart postfix
發送一封測試郵件以確保配置正確:
echo "This is a test email." | mail -s "Test Email" your_email@example.com
創建一個Python腳本來發送郵件。以下是一個簡單的示例:
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
# 郵件發送者
sender_email = "your_email@example.com"
# 郵件接收者
receiver_email = "receiver_email@example.com"
# SMTP服務器地址
smtp_server = "your_hostname.example.com"
# SMTP服務器端口
smtp_port = 587
# SMTP服務器認證
smtp_username = "your_email@example.com"
smtp_password = "your_email_password"
# 創建郵件對象
message = MIMEMultipart()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = "Test Email from Python"
# 郵件正文
body = "This is a test email sent from Python."
message.attach(MIMEText(body, "plain"))
# 連接到SMTP服務器并發送郵件
try:
server = smtplib.SMTP(smtp_server, smtp_port)
server.starttls()
server.login(smtp_username, smtp_password)
text = message.as_string()
server.sendmail(sender_email, receiver_email, text)
print("Email sent successfully!")
except Exception as e:
print(f"Failed to send email: {e}")
finally:
server.quit()
保存上述腳本為send_email.py
,然后在終端中運行:
python3 send_email.py
如果一切配置正確,你應該會收到一封測試郵件。
通過以上步驟,你就可以在CentOS上配置Python郵件發送功能了。
