arkadaşlar merhaba,
hiçbir güncelleme vs yapmama rağmen wordpress sitelerim (hepsi aynı sunucuda) aniden mail gönderimini kesti. SMTP ayarlarını doğru şekilde yapılandırıyorum ama nafile.

whm tarafında nereye bakmam gerekir bununla ilgili?

yandex harici kendi posta sunusunu kullanan sitelerde de aynı problem oluştu. Yıllardır çalışan mailler bir anda gitti.
