How to open SMTP ports and access your Mail Server

It’s impossible to imagine a world without emails. And it’s all possible thanks to mail servers that work round the clock to transmit your information securely from one end to another.

Why use VPN with mail server?

While communicating with your mutual, friends, family or communication between business clients we all share a lot of the personal information, pictures, subscriptions, and business data, which we wouldn’t want to be easily snooped on by any outsider or unauthorized person. Therefore, it is very important to make your email secure and anonymous. A reliable VPN for your email client will encrypt your email account and restrict email access to a chosen VPN IP address. When connected to a VPN connection, your real IP address will hidden from the malicious websites trackers and hackers, making you untraceable on the public Internet.

Port Forwarding issues with mail server

While connected to a VPN, you may face the issue that your email client is unable to send the mail to the other party i.e. the mail sit in your outbox while your other operations and surfing works fine on the internet. This usually happens when your network and firewall are blocking email ports such as SMTP (port 25), POP3 (port 110 and 995), and IMAP (port 143 and 993).
