这是场景, 我有在公共IP上运行的plesk服务器。 我有一个指向该IP的域。 screenshot
我用mxtoolbox.com
告诉我,我的mail.domain指向我的plesk服务器的IP。
问题是我无法在roundcube邮件客户端中接收邮件。 而是1天后,我收到了来自“ mailer-daemon@googlemail.com”的邮件 screenshot2
答案 0 :(得分:0)
所有邮件传输协议端口均已关闭,因此无法接收邮件:
boolean addPerson (String[] sourceAllPeopleInMyFamily) {
HashMap<String, ArrayList<Person>> allPeople = pointer to another initialized HashMap in another package;
HashSet<Person> allPeopleInMyFamily = new HashSet<Person>();
for (Map.Entry<String, ArrayList<Person>> entry : allPeople.entrySet()) {
for (String sourcePersonInMyFamily : sourceAllPeopleInMyFamily) {
Person personInMyFamily = new Person (sourcePersonInMyFamily); // Create a new person based on sourceAllPeopleInMyFamily array
if (entry.getValue().contains(personInMyFamily) { // Check if personInMyFamily exists in all people set
if (!allPeopleInMyFamily.add(personInMyFamily))
return false;
// } else { return false; } ???????
}
}
}
}
您需要允许防火墙上的传入连接。 也看看这篇文章-Which Ports Need To Be Opened for all Plesk Services to Work with a Firewall?
