Page history last edited by trunasuci 15 years, 1 month ago


For subscribers of TMNET ( dialup/streamyx DSL/other ) that setup their MTA especially on Postfix, they'll face the problem when sending mails t other email such as yahoo wth error "status=deferred" like this:


Mar 21 04:12:31 server2 postfix/smtp[22938]: 18BAF147C37: to=<info@jusbp.org>, relay=none, delay=134093, delays=134030/0.11/62/0, dsn=4.4.1, status=deferred (connect to mail2.jusbp.org[]:25: Operation timed out)

Mar 21 04:13:24 server2 postfix/smtp[22930]: 5A5A1147C42: to=<webmaster@escwa.org.lb>, relay=mx1.escwa.org.lb[]:25, delay=56563, delays=56447/0.05/30/85, dsn=4.0.0, status=deferred (host mx1.escwa.org.lb[] said: 450 <nurain@******.com>: Sender address rejected: Domain not found (in reply to RCPT TO command))

Mar 21 04:14:38 server2 postfix/smtp[22936]: 02D4F147C3D: to=<publicrel@iman.ut.ac.ir>, relay=iman.ut.ac.ir[]:25, delay=123389, delays=123199/0.09/190/0, dsn=4.4.2, status=deferred (lost connection with iman.ut.ac.ir[] while receiving the initial server greeting)




after long investigation, and thinking that I setup this Postfix wrongly... i found out that the problem exist on the provider/ISP TMNET for port 25..



so i fixed the Postfix and added this line in main.cf:


relayhost = smtp-proxy.tm.net.my:25




and reload the postfix.. try to resend/send your email all over again.. and check the maillog...



and surprisingly WALLA!!! it works!!

Mar 21 05:16:13 server2 postfix/pipe[44952]: 4689C147C27: to=<trunasuci_74@yahoo.com>, relay=spamassassin, delay=15, delays=0.12/0.01/0/14, dsn=2.0.0, status=sent (delivered via spamassassin service)
