What is an SMTP Relay Service Servers Usage and Benefits

Of all the technologies brought to us in the age of the internet perhaps the one we take most for granted is Email. Email truly did change the way that the world communicates and perhaps a testament to its success is that fact that the email mechanism hasn’t changed much from the very earliest days, SMTP still rules!

For starters SMTP stands for Simple Mail Transfer Protocol, which lets you send email anywhere, you may choose to do so with any email service or through various email clients. In order to send e-mail messages, we need to use an SMTP server.

What is an SMTP Relay in Computer Network

An SMTP Relay Service is the service behind any email program you choose to use whether it’s a desktop application or web-based app; all of these email programs depend on SMTP relaying services in order to let your email client send the email you are sending.

Almost 99% of all email programs need the details of an SMTP relay server in order to function, but sometimes this information can be the hardest to find. Various ISPs and other email providers seem determined to hide their SMTP server details as far away from visible sight as possible and whilst it’s not a big deal when you’re working from your home computer but the need to have those server details when you’re traveling can be the difference between being able to send emails.

SMTP is a simple protocol but one on which we rely on a lot. Sometimes your emails can’t be sent because of your ISP’s SMTP relay service being blocked. This is where a relay service can be useful.

An SMTP relay service sort of bypasses your current ISP and any type of restrictions it might have ( for example some ISP have some ports blocked, another one could be the size of the emails you are sending, etc.) Another feature is that it helps you send emails in a more professional manner, meaning instead of sending myemail@mycurrentinternetserviceprovider you could easily send an email with myprofessionalemail@mysite.com.

There are several SMTP Relay Services Providers that can help you deliver your message without restricted access or annoying email delivery rate.

Whether you are already using an SMTP Service Provider through a hosting account or an ISP. You should know that one of the best ways to ensure your emails are truly delivered is using a professional service such as Duocircle, not only it allows you to bypass many filters that may disrupt your delivery ( DKIM, SPAM Filters, etc.) but also allows you to track your correspondence, the best part is that you can use Duocircle in

  • Hotels,
  • Airports,
  • Your Office
  • Home

and be truly assured that your email will be delivered no matter what.

Why do we need to use SMTP Relay Servers?

Thanks to widespread abuse by spammers the days of open relay SMTP servers seem long gone. It’s a shame because the ability to relay our messages through widely available SMTP servers made the whole job of sending an email so much easier. Instead, we are left in a situation where the average person has between 6 and 10 e-mail accounts – each of which has its own SMTP server for sending messages through – all of which require us to remember usernames and passwords. It’s no wonder then that one of the biggest tasks facing ISP support desks is resetting passwords for email accounts.

The situation can be even worse if your ISP blocks port 25 traffic. In order to send e-mail, all messages must be routed through their relay server. To go along with this many ISPs also limit access to this SMTP server to only users who connect via their service. This is a huge issue. From your home, you may not notice this but the second you travel you suddenly find that the SMTP settings you’ve been using no longer work (access denied).

For people who travel as either part of a business or especially those who travel for leisure there has always been the need for a simple SMTP solution that would allow one set of smtp settings to be used anywhere in the world and on any network.

Whilst several services offer relaying if you authenticate yourself (Gmail for example) they do have issues with sending emails on behalf of other addresses. To the recipient, this can all look very confusing (emails appearing to come from several addresses). To date, we have only found one service that truly allows you to relay messages from any device, from anywhere in the world. It is a service that goes by the name of Duocircle.

Duocircle is the closest thing to a good old-fashioned open relay server that you’ll find. It is one of the best smtp relay mail host out there. For a very small fee they let you use their server to relay mail messages from as many email accounts as you like – you get to retain the existing email addresses you simply use their SMTP server to do the sending. It works a treat across all devices, from desktops and laptops to iPhones.

For those people who have port 25 blocked by their ISP, an email relay service will even allow you to connect to their server on several other ports making it the perfect solution for your home email as well. By using a relay SMTP server you can retain one set of settings for all your email addresses and then when you’re on the move you’ll still have no problems sending an email. Put it this way, if you can find a wireless hotspot to connect to the internet then you’ll be able to use an SMTP relay server to send your emails!
