SMTP和POP3協(xié)議概述
SMTP協(xié)議稱為簡(jiǎn)單郵件傳輸協(xié)議，是一組用于從原地址到目的地址傳送郵件的規(guī)則，由它來(lái)控制信件的中轉(zhuǎn)方式。SMTP協(xié)議屬于TCP/IP的協(xié)議簇，SMTP是負(fù)責(zé)郵件服務(wù)器之間的寄信的通信協(xié)定 POP3協(xié)議稱為郵局協(xié)議版本3,也是TCP/IP協(xié)議簇的一員，基于POP3協(xié)議的服務(wù)器是用來(lái)接收信件的。每個(gè)Email地址一般只有一個(gè)如果想要同時(shí)收取多個(gè)郵箱的信件，就需要挨個(gè)設(shè)置每個(gè)郵箱的POP3服務(wù)器地址。

效果
打開tomcat服務(wù)器和foxmail郵件服務(wù)器，然后進(jìn)入該web首頁(yè)，點(diǎn)擊注冊(cè)，可以在foxmail中看到對(duì)應(yīng)的[email protected]郵箱中有一封注冊(cè)郵箱，點(diǎn)擊該郵箱中的鏈接，就進(jìn)入了激活頁(yè)面，然后該注冊(cè)的賬號(hào)就激活注冊(cè)成功了
以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持服務(wù)器之家。
