Mail port 587
Port 587 is a common alternative to port 25 for sending email. Here's what you need to know:
What is port 587?
Port 587 is a Transmission Control Protocol (TCP) port used for sending email messages. It's also known as the "submission" port, as it's used by email clients to submit email messages to a mail server.
Why is port 587 used?
Port 25 (SMTP) is the traditional port used for sending email, but it's often blocked by internet service providers (ISPs) and firewalls due to spam and security concerns. Port 587 was introduced as an alternative to port 25, allowing email clients to send email messages to a mail server without compromising security.
How does it work?
When you set up an email client to use port 587, you're telling it to send email messages to your mail server using this alternative port. The mail server then forwards the email messages to their final destination.
Benefits of using port 587
Using port 587 can help you avoid issues with port 25 being blocked or restricted by your ISP or firewall. It's also a good idea to use port 587 if you're using a public Wi-Fi network or a network with strict security policies.
Common email clients that support port 587
Many email clients support port 587, including:
- Microsoft Outlook
- Mozilla Thunderbird
- Apple Mail
- Gmail (using IMAP or POP3)

The process for setting up port 587 varies depending on your email client. Here are some general steps:
