Dear all,
Aku punya server postfix sebagai relay dari bbrp domain.
Ternyata ada salah satu domain (ekadharma.co.id) yang tidak bisa kirim email ke telkom.net dengan error dibawah ini.
maillog.4:Sep 7 07:20:39 postfix postfix/smtp[23491]: 12418157DA: to=<[EMAIL PROTECTED]>, relay=in-mta3.plasa.com[202.134.0.73], delay=121, status=bounced (host in-mta3.plasa.com[202.134.0.73] said: 550-Callback setup failed while verifying <[EMAIL PROTECTED]> 550-(result of an earlier callout reused). 550-The initial connection, or a HELO or MAIL FROM:<> command was 550-rejected. Refusing MAIL FROM:<> does not help fight spam, disregards 550-RFC requirements, and stops you from receiving standard bounce 550-messages. This host does not accept mail from domains whose servers 550-refuse bounces. 550 Sender address [EMAIL PROTECTED] does not exist (in reply to RCPT TO command))
Anehnya domain lain tidak mengalami masalah untuk pengiriman email ke domain telkom.net ini.
Kira-kira dimana titik errornya.
Mohon pencerahan.
Wassalam, INos
