Corporate SMTP Relay -The Missing Component
SMTP stands for Simple Mail Transfer Protocol. This protocol is used on the internet over TCP/IP stack, as a standard to transfer e-mail messages from once server to the other server. The default connecting port for this is port number 25.
Mail messages are transferred using this protocol. For example, if you send a mail from your Gmail account (configured to Thunderbird) to a friend at Microsoft, the mail server of Gmail first finds the MX server of Microsoft and opens a socket connection to it. Henceforth, the data is transferred via your internet connection to the Microsoft MX server using Gmail servers in the transition. This data transfer is over TCP/IP and the application layer packets are in SMTP standard.
SMTP connection can be setup over ANY internet connection. The IP in that case would be one, two or more, but a few. The internet is a network of networks. There are uses and misuses of this technology. Some individuals use the medium of e-mail to spread marketing messages that are at times unsolicited by the receiver. And some send hoax e-mails to dupe the receiver into sending some money. This is a mal-practice known as Spamming and individuals/groups that do it are called Spammers. Such e-mail messages are called Spam.
Over the years, several ways have been devised to detect spam and reject/block it before it hits mailing servers; this saves time of people and helps in productivity. This has become a viable business opportunity for some companies. One of the companies that helps detect spam is Spamhaus.com. They have a list of IPs that are considered as spam generator and “Black-list” such IPs. There is a standard procedure to get an IP “White-list”ed. Many software use repositories like Spamhaus and others, to stop spam.
Thus, its important to have your IP in the White List of such repositories/authorities. Being a expert in this market, we have the know-how to deliver mails in the in-box of an e-mail. This is in contrast to spam mails landing in the spam folder of recipients.
We have solution with multiple layers of servers connected with a 300 Mbps line that are pure SMTP servers. They are connected to a reporting server which hears and tabulates bounced mails with the reasons for the bounce. Our SMTP servers are used to ensure delivery of the mails. This ensures a high delivery because we also know the patterns on which ISPs like Gmail/Yahoo designate spam. This is based on the number of mails sent through a particular IP address. Thus, we DNS round-robin through all the IPs before the mail is successfully delivered to the intended recipient’s mailbox.
We offer our SMTP servers to the client. The details that are delivered to a client are as follows:
1) SMTP URL
We offers a delivery rate of greater than 90%. This is a vouched for delivery rate in the industry and in the high range in India.
Depending on the type of traffic, we can have:
1. SMTP Relay for Promotional Mails
2. SMTP Relay for Corporate Mails
We have multiple IPs for both and in Corporate SMTP, the delay is minimal.

From Email Server, mails will be pushed to our SMTP Servers. Mails will be routed to outside world from SMTP Servers. Incoming mails will be forwarded from existing service provider to our account to access by multiple users. For bounce processing, all the mails reaching to the from address’s mails will be forwarded to our account
Countless IP addresses
Bounce reporting possible
Almost no chance of blacklisting
