Vesta Panel ücretli panellerden sonra, alternatif olarak sunulan ücretsiz Linux Hosting panellerinden en çok tercih edilenlerden bir tanesi. Oldukça stabil çalışması, sade arayüzü, apache ve nginx desteği ile Linux Hosting kullanıcıları tarafından tercih ediliyor.
Vesta Panel mail sunucu tarafında MTA olarak Exim, pop3 ve imap sunucusu olarak da Dovecot yazılımı ile kuruluyor. Spam filtresi olarak SpamAssasin kullanıyor.
Eğer spam sorunundan muzdaripseniz aşağıda verilen SpamAssasin konfigürasyon dosyası ile spam sorununu bir nebze de olsa çözebilirsiniz.
Sunucunuza SSH üzerinden root olarak bağlanın ve dizine gidin;
/etc/mail/spamassassinDosyayı oluşturun ve açın;
nano custom_SA-rules.cfİçine aşağıdaki kuralları yapıştırın;
# Short-Circuit if found in local blacklist or whitelist
