All are well know about the E-mail clients it is a application software used in the Computers to Download the Mail from there E-mail accounts by with the help of POP3 (Incoming mail server address) and SMTP (Outgoing mail server address) IMAP (also Income mail server address) and read them offline .
The main difference between POP3 and IMAP is POP3 downloads full mail in to the E-mail client and the IMAP Downloads only subject of the mail it will fully download after clicking the subject. But free E-Mail accounts are not have this services (POP3,IMAP,SMTP).
But the Gmail provides this service to their users. Follow the steps to access Gmail account in E-Mail clients.
➢ First login in to your Gmail account
➢ Click settings in Right-Top of the Account
➢ Select POP/Format or POP/Formate and IMAP
➢ Choose the POP access option and the process is half completed
And your POP server address(Incoming mail server address) is POP.GMAIL.COM and SMTP server address(Outgoing mail server address) is SMTP.GMAIL.COM and use your Gmail user name and password to access. In case yo are selected the IMAP the server address is IMAP.GMAIL.COM.The incoming server port is 110(General port) or 995 (secured port SSL). Outgoing server port 25 (General port) or 465 (Secured port SSL). I recommend that use Incoming and Outgoing secured ports 995 and 465 for secured mail download. When your client or E-mail account not have a SSL (secured ports) use General or default ports 110 and 25.
