[IMail Forum] Undeliverable Problem

[Bill Yang]

Dear professionals,   We found that imail mail server can't deliver email to some email addresses. At first, we think that there is must something wrong with their mail server. Because our mail server can deliver email to most recipients successfully. But we change our mind soon. Because those recipients, who can't receive our email, are employees at world's top 100 companies. Furthermore, we can use other email accounts such as Yahoo and hotmail to send email to them. So we believe that our imail server was not set correctly now. The following are typical error snippet of our imail log:   20020711 000936 127.0.0.1       SMTP (2140) Trying pg.com (0) 20020711 000937 127.0.0.1       SMTP (2140) Connect pg.com [192.44.184.177:25] (1) 20020711 001035 127.0.0.1       SMTPD (008400FA) [210.192.99.144] connect 210.192.99.144 port 3311 20020711 001136 127.0.0.1       SMTPD (008500FA) [210.192.99.144] connect 210.192.99.144 port 3314 20020711 001235 127.0.0.1       SMTP (1940) s: s 20020711 001235 127.0.0.1       SMTP (1940) 20020711 001235 127.0.0.1       SMTP (1940) SMTP_DELIV_FAILED 20020711 001235 127.0.0.1       SMTP (1940) >QUIT     We also find the following log message:   20020711 200608 127.0.0.1       SMTP (1972) Trying unilever.com (0) 20020711 200608 127.0.0.1       SMTP (1972) Connect unilever.com [194.60.106.6:25] (1) 20020711 200608 127.0.0.1       SMTP (1972) 221 2.0.0 uedcm034.danone.com closing connection 20020711 200608 127.0.0.1       SMTP (1972) >EHLO propackchina.com 20020711 200613 127.0.0.1       SMTPD (02840166) [210.192.99.144] connect 210.192.99.144 port 2079 20020711 200714 127.0.0.1       SMTPD (02850166) [210.192.99.144] connect 210.192.99.144 port 2082 20020711 200717 127.0.0.1       SMTP (1972) 220 mail04.unilever.com (Mail*Hub TurboSendmail) ESMTP Service ready 20020711 200717 127.0.0.1       SMTP (1972) >MAIL FROM:<[EMAIL PROTECTED]> 20020711 200717 127.0.0.1       SMTP (1972) 250-mail04.unilever.com 20020711 200717 127.0.0.1       SMTP (1972) 250-EXPN 20020711 200717 127.0.0.1       SMTP (1972) 250-8BITMIME 20020711 200717 127.0.0.1       SMTP (1972) 250-PIPELINING 20020711 200717 127.0.0.1       SMTP (1972) 250-DSN 20020711 200717 127.0.0.1       SMTP (1972) 250 SIZE 2147483647 20020711 200717 127.0.0.1       SMTP (1972) >RCPT To:<[EMAIL PROTECTED]> 20020711 200718 127.0.0.1       SMTP (1972) 250 sender <[EMAIL PROTECTED]> OK 20020711 200718 127.0.0.1       SMTP (1972) >RCPT To:<[EMAIL PROTECTED]> 20020711 200718 127.0.0.1       SMTP (1972) 250 recipient <[EMAIL PROTECTED]> OK 20020711 200718 127.0.0.1       SMTP (1972) >DATA 20020711 200719 127.0.0.1       SMTP (1972) 250 recipient <[EMAIL PROTECTED]> OK 20020711 200719 127.0.0.1       SMTP (1972) SMTP_DELIV_FAILED 20020711 200719 127.0.0.1       SMTP (1972) >QUIT     Any help would be greatly appreciated!   Best regards, Bill Yang
