If you have a cloud hosting account and you create an email address, you may take the option to send out and receive messages for granted, however, this is not always the case. Sending emails isn't always included in the hosting packages that providers offer and an SMTP service is necessary to be capable to do that. The acronym represents Simple Mail Transfer Protocol and this is the software application that allows you to send out e-mails. If you use an e-mail application, it creates a connection to the SMTP server. The latter then searches the DNS records of the domain, which is a part of the receiving address to find out which email server manages its email messages. After system information is swapped, your SMTP server provides the email to the remote IMAP or POP server and then the email is finally delivered in the corresponding mailbox. An SMTP server is required if you work with some kind of contact page as well, so if you use a cost-free hosting plan, for example, it is likely that you will not have the ability to make use of this type of form since many no charge hosting service providers don't allow outgoing e-mail messages.
