Mình có cấu hình một server email bằng CentOS + Postfix + Dovecot + Sasl + OpenSSL.
Sau khi cấu hình xong thì dùng tài khoản đứng trên server gửi và nhận email bình thường trên tất cả các server mail hiện tại như gmail,yahoo,hotmail.
Nhưng khi dùng email client như outlook thì chỉ có thể nhận được email do các mail server kia gửi nhưng không thể gửi ngược lại cho các email server đó được.
Đây là log khi mình gửi email cho server mail Yahoo bằng outlook:
Code:
Aug 17 16:05:02 s2 postfix/smtp[3947]: connect to yahoo.com[206.190.36.45]:25: Connection timed out
Aug 17 16:05:02 s2 postfix/smtp[3947]: 5D09B3142D79: to=<quanvq89@yahoo.com>, relay=none, delay=91, delays=0.74/0.01/90/0, dsn=4.4.1, status=deferred (connect to yahoo.com[206.190.36.45]:25: Connection timed out)


Đây là cho gmail:

Code:

- Nếu như mình dùng telnet locahost 25 thì gửi nhận email bình thường.
- Lỗi trên là dùng outlook gửi email thi bị
