XenForo'da SMTP mail ayarlarını yaparken ya da farklı bir uygulamada SMTP üzerinden mail göndermeye çalışırken aşağıdaki gibi bir hata alabilirsiniz:

Bash:

SMTP 5.7.0 Must issue a STARTTLS command first

Bu hata, sunucunun TLS (şifreli bağlantı) olmadan iletişime izin vermediğini gösterir. Eğer kullandığınız SMTP istemcisi TLS desteği sunmuyorsa veya farklı bir yapılandırma gerektiriyorsa, Plesk sunucunuzda bu zorunluluğu devre dışı bırakmanız gerekebilir.

PuTTY İndir

🔧 Çözüm: Postfix Ayarlarını Düzenleyin

SSH ile sunucunuza bağlanın.
Aşağıdaki dosyayı düzenleyin:

Bash:

nano /etc/postfix/master.cf

Dosyanın uygun bölümüne aşağıdaki satırları ekleyin veya varsa düzenleyin (genelde bu komutlar eklidir, mevcut kodları düzenleyiniz):

Bash:

smtpd_enforce_tls=no
smtpd_tls_security_level=may

Yukarıdaki kodları düzenlemek için, CTRL + W, sonra smtpd_enforce_tls yazıp, ardından mevcut komutu düzenleyebilirsin.

smtpd_enforce_tls ve smtpd_tls_security_level her iki kayıtta değişecektir.

Bu ayarlar, STARTTLS zorunluluğunu kaldırır ve TLS desteği isteğe bağlı hale gelir.

🔁 Postfix Servisini Yeniden Yükleyin

Bash:

service postfix reload

Yanıtlamak için burayı tıklayın.
