What is the postal server?
MailServer is a web server set up for e -mail processing by installing two programs: A SENDMail and pop . Pop (post office protocol) collects mail sent to you. Mail servers can be installed on the main web server or on a separate server.
Sendmail allows Mailserver to process outgoing e -mail. If the e -mail address does not exist, the server will return the mail to the sender. If the server has a technical problem when trying to deliver mail and is unsuccessful, the post office may also be returned. In all cases where the post office is returned, it comes with an explanation or error code. By reading the error code, you can determine why the post office has not reached its destination.
Pop program collects incoming e -mail. When it receives mail, it creates a single text file of accumulated messages for each e -mail address. This text file can grow very large. If the end user configured his e-mail client to remove the mail from the servosThe eruption collection is a text file of the postal server deleted when the mail gathering. However, some people store e -mail on the server. This is not just concerns about personal data protection, but can also lead to failures when text files become too lengthy.
Another collection program is called Internet Message Access Protocol (IMAP). IMAP operates web postal services like Yahoo!, Hotmail and more. If you are using the website to collect mail, you approach IMAP Mailserver.
Virtually every website domain is associated with Mailserver. Internet service providers (ISP) also offer e -mail services and postal server features. If the server does not offer built -in filtering of content, you can install your own spam filter. Free spam filters are very popular and are available online.
Mailserver can also be installed on your own computeri. If you run this type of server, the mail may not travel via your ISP and provide a certain degree of privacy. Starting your own server also ensures that you can always send or receive mail even if the postal server is ISP below.
Unfortunately, many people who run personal mail servers use them to send spam. As a result, Internet service providers commonly prohibit this in the Terms and Conditions Agreement. However, some Internet service providers allow users to operate a personal server if they sign a contract that guarantees that it will not be used for spam.
