Assume that we have sent a E-Mail to the address of abc@gmail.com through GMAIL mail engine. Since we have sent it through GMAIL, our mail is sent to the GMAIL SMTP server via the port 465. Then it reads the recipient's address. The part after the @ says recipient also holds an gmail account. So, SMTP server redirect the mail to GMAIL POP3 server. POP3 server identifies the particular recipient from the address part before the @ and link the particular mail to his account. Recipient log into the POP3 server using his user name and password and read the mail.

Assume what happens if we have sent the particular mail to abc@gmail.com via the YMAIL mail engine. If so, YMAIL SMTP server look at the address part after the @ and understand that recipient doesn't has an account in YMAIL POP3 server. So, it re-directs the mail to the particular SMTP server indicated at the address. After it has been sent to the GMAIL SMTP server same routine is happening as mentioned in the above paragraph.
