What is my SMTP server?

Could you please clarify for me what SMTP server you are referring to? Are you asking about the specific SMTP server used by your email provider, or are you perhaps inquiring about setting up an SMTP server for your own purposes? If it's the latter, I can guide you through the steps involved in selecting a reliable SMTP server provider and configuring it to suit your needs. Alternatively, if you're unsure about the SMTP server associated with your email account, I can help you find that information as well.
