Allo
Saya lihat di log smtp sy, banyak email yg tdk terkirim, katanya "server
refused to talk to me: 421 Too many concurrent SMTP". Saya coba lebih
spesifik dalam melihat log, di peroleh bahwa email masuk tgl 28 jam
14:16, lalu kenapa di tolak pada pukul 15:21, padahal seharusnya email
itu masuk di queue. Kenapa malah email itu mental ke sender.
saya coba ng'google tapi belum ketemu pencerahaannya. Tolong dong. Apa
yang perlu saya cek.
Agar lebih enak log nya saya persempit. Ini log hanya dari satu alamat
email, dimana sebenarnya ada beberapa email yang seperti ini.
