It is the system that helps send emails from one server to another.

You don\u2019t need to build or manage the server yourself.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With a hosted SMTP service, you get access to a reliable server that is always online. This helps ensure that your emails are sent quickly and correctly. Hosted SMTP is used by businesses that send a lot of emails, like e-commerce stores, marketing agencies, or customer service platforms.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Hosted_SMTP_vs_Self-Hosted_SMTP_Server\"><\/span><b>Hosted SMTP vs Self-Hosted SMTP Server<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Let\u2019s understand the difference between a <\/span><b>hosted SMTP server<\/b><span style=\"font-weight: 400;\"> and a <\/span><b>self-hosted SMTP server<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When you use a <\/span><b>self-hosted SMTP server<\/b><span style=\"font-weight: 400;\">, you are running the email server on your own hardware or hosting account. This gives you full control but also means more responsibility. You must handle security, maintenance, updates, and spam prevention yourself.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With a <\/span><b>hosted SMTP service<\/b><span style=\"font-weight: 400;\">, you pay a company to manage the SMTP server for you.

They also show error codes like 550 (mailbox not found) or 421 (server not available).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Reviewing logs helps you understand what went wrong.

A blacklist is a list of servers that are known for sending spam or unwanted emails. If your <\/span><b>hosted SMTP server<\/b><span style=\"font-weight: 400;\"> is on such a list, your emails may get blocked.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To check if your server is blacklisted, use tools like MXToolbox or DNSBL. Enter your SMTP server\u2019s IP address and check the results.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If your server is blacklisted, contact your <\/span><b>hosted SMTP service<\/b><span style=\"font-weight: 400;\"> provider. They may move you to a different IP or help remove the IP from the blacklist.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you are using a <\/span><b>self-hosted SMTP server<\/b><span style=\"font-weight: 400;\">, you must take extra steps to secure your server and request delisting from blacklists yourself.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_8_Use_a_Different_Port_or_Encryption\"><\/span><b>Step 8: Use a Different Port or Encryption<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">SMTP servers usually support multiple ports.

Also, check whether you\u2019re using the correct encryption method.

You can also use web-based SMTP testing tools.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If emails are sent successfully using another tool or address, then the issue is with your original app or email setup.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This method helps isolate the problem so you can fix it faster.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_10_Contact_Your_SMTP_Support_Team\"><\/span><b>Step 10: Contact Your SMTP Support Team<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you\u2019ve tried all the steps above and still can\u2019t solve the problem, it\u2019s time to contact your <\/span><b>hosted SMTP service<\/b><span style=\"font-weight: 400;\"> support team.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most SMTP providers offer live chat, email, or ticket-based support.
