Merhaba
Hakan OZAY'ın http://www.enderunix.org/docs/qmail-install.php belgesine
gore bir qmail server kurduk. Sunucu 1 yildir kesintisiz ve cok verimli
calisti. Fakat bugun icin anlayamadigimiz sorunlar yasanmakta, soyle ki;
sunucu uzerinde kayitli 350 kullanici var ve smtp/run ayarlarinda "max SMTP
baglanti" 150, ancak smtp portuna gelen istek sayisi su an icin 350
civarlarinda, spam ile Dos atagi olsa gerek, cunku mail gondermek
istediginizde "basarisiz SMTP baglantisi lutfen Sistem yoneticisini
arayiniz vs seklinde bir mesaj geliyor ve mail gonderilemiyor". Mail
gonderebilirsek de bu defa ayni mailden pek cok sayida gidiyor ve/veya cok
sayida geliyor.
Benzer durumu yasayan oldu mu? cozum konusunda ne yapildi/yapilabilir
qmail-smtp/run dosyasi da asagidaki gibidir.
