A2A: Is there any procedure to use multiple SMTP servers in sending emails?

You can have some kind of round robin mechanism that polls a set of SMTP servers to send mail. In effect this is just a configuration file read by code that acts as a relay server, and I’m sure there must be a project that implements it somewhere.

I have this clarified in details with a video. You could simply watch it. It's called "How e-mail works" This video shows how a basic SMTP server works. It is an in-depth video revealing exactly what occurs when you strike send button on your mail customer. You can figure out anything you need to learn from right here.

SMTP mail server is a machine, or collection of machines, whose primary purpose is to send, receive, and/or relay messages between email senders and receivers. An SMTP server will have an address, or addresses, that can be set by the mail client or application that you are using, generally formatted as http://smtp.serveraddress.com

You can only send through one at a time. If you have access to more than one SMTP server you can manually change between which one you currently want to use.

An SMTP server is a mail server that uses the Simple Mail Transfer Protocol to send and receive emails. An outgoing mail server, on the other hand, is a mail server that routes email messages from your email client to the right SMTP server. Outgoing mail servers are also sometimes referred to as relay servers.

In short, SMTP sends emails to their destination. You can think of it as a postal worker picking up mail from your home, finding the correct destination route, then delivering it to the recipient mailbox.

There are two types of SMTP servers you'll come across:

'Regular' SMTP servers for sending everyday personal email.

Dedicated SMTP relay servers for sending bulk email and transactional emails.

What is an effective SMTP really?

A SMTP server is available on any Linux installation or you can run one locally on Windows or Mac, but it really depends on what you want to use it for. If you want to spam, there is no way to get an effective one, you will be blacklisted in any case.

What is SMTP server name?

The name of the remote system to which you are going to send mail.

This is information which is supplied to you by your ISP.

It’s still possible but harder. If your Gmail is not set up for SMTP and less secure apps, you cannot use SMTP directly, you need to use OAuth. In Wordpress, that can be done via this:

WP Gmail SMTP

Another option is using a service such as SendGrid, Amazon S3 or Mandrill to handle your email sending. It’s not free but the cost is reasonable if you don’t send too many emails.

Make a configuration file with all smtp server and credentials

Then loop through multiple smtp servers and send email.

Generally some users do it often to not exceed daily limit free smtp server daily limit.

Like you can use Gmail smtp setting with yahoo smtp server so that one batch of email goes with yahoo and next goes with gmail.

It is part of custom programming or back up email server setting in some of softwares.

For affordable and reliable SMTP servers, consider iDealSMTP, Sendinblue, and Mailgun. iDealSMTP stands out for its cost-effectiveness and robust features, while Sendinblue and Mailgun offer competitive pricing and reliable performance for sending emails.

Yes, that is what a SMTP server generally does which is relay email. They relay email from a client of a domain to a server of another domain or relay emails between servers. For security reason most SMTP servers are configured to only accept email from trusted or authenticated sources. An open relay is an SMTP server that will relay email from any source without authentication which is not a good idea as people with bad intentions will misuse this and lead to numerous problems.

To get an effective SMTP server, choose a reliable provider like iDealSMTP, known for its high deliverability rates, best security, and excellent customer support. Ensure it offers scalability, easy integration, and comprehensive analytics for optimal email performance.

Yes. The 'Send As' facility only affects the From: mail header, which can be anything that looks like a mail address and doesn't even have to exist. This is not special to Gmail, it's a 'feature' of all Internet email systems and one of the root causes of the existence of spam. In the case of Gmail, other headers still identify the real origin.

The SMTP server for Gmail is smtp.gmail.com, typically using port 587 for TLS or 465 for SSL. For reliable and cost-effective bulk email services, I recommend SMTPget—I’ve used it, and it’s excellent and affordable.

SMTP Authentication, often abbreviated SMTP AUTH, is an extension of the Simple Mail Transfer Protocol (SMTP) whereby a client may log in using any authentication mechanism supported by the server. It is mainly used by submission servers, where authentication is mandatory.

To set up an SMTP server for bulk email sending, configure a dedicated server with email software like PowerMTA or iDealSMTP. Set up SPF, DKIM, and DMARC for authentication, warm up IPs, and manage IP rotation for deliverability.

The SMTP server for Gmail is smtp.gmail.com. To use it, set the port to 587 for TLS or 465 for SSL. Authentication is required using your Gmail email address and password. For more details, check out DigitalAka™ for comprehensive guides and troubleshooting tips.

to send a mail as an alias on gmail, you have to use the SMTP authentication access of your website, Google will accept the mail and send it to your web host and so send it over them.

There is no other way to do that because spam filter requirements are much tighter than a few years ago and it will just not work to send mails with another domain via the Gmail servers.

I think that worked before (maybe in 2010) and I have used that, but it is not supported now because the mail will do be accepted by most other mail servers.

Gmail’s SMTP server is smtp.gmail.com, and you’ll need to use either port 465 (SSL) or 587 (TLS) to connect to it.

The SMTP server info is generally provided by your email service provider. If you're unsure of your SMTP server info, you can usually contact your email service provider for help.

Mailchimp typically doesn’t allow the use of external SMTP servers to send emails. Instead, it operates on its own infrastructure for email delivery. When you use Mailchimp, you’re essentially utilizing their platform to design, manage, and send emails to your subscribers. They handle the technical aspects of email delivery, including SMTP, behind the scenes. So, you wouldn’t typically configure Mailchimp to use a different SMTP server. If you have specific requirements or limitations, you might want to reach out to Mailchimp’s support for clarification and assistance.

How do I send an email from an SMTP server?

The same way you send e-mail from any other computer: You log in, you run an e-mail program, you type in your message, and you issue a send command in whatever way the program expects.

You don’t need to care about whether it’s an SMTP server or not; that’s not your problem.

SMTP is shorthand for Simple Mail Transfer Protocol, one of the early messaging (email) protocols on the Internet. So an SMTP server is a server handling mail traffic. The SMTP server address is the IP / DNS entry for the SMTP server. The actual values will depend upon the company and hence is not something anyone can tell you without knowing who you are and which company you’re working with / for.
