belirteyim. Zira orda RCPT TO olarak kullandigi adrese mail gonderip
gonderememesi onemli. Qmail ve bircok mail sunucu(Exchange vs) RCPT TO'dan
sonraki ilk @ degil de son @ ' den sonraki ve onceki kismi aliyor.

[EMAIL PROTECTED]'ye degil de [EMAIL PROTECTED]@enderunix.org adresine gitmeye
calisacaktir. EnderUNIX domaininde boyle bir adres olmadigi icin muhtemelen hata
alacaksiniz.

cevap veriyor. Bence bu ozellik daha buyuk bir guvenlik acigi olusturuyor Zira
sisteminizdeki local kullanicilar deneme yanilma yoluyla bulunabilir.

Sonuc olarak bu sekilde karsilastirmalar ile MTA'lar arasi bir ustunluk
belirlenemez. Varsa ustunluk tasarimlarinda ve kodlamalarindadir ki her
ikisinide uzun yillardir kullaniyorum, bence yeterli derecede
guvenliler.
