Debian - Postfix - Unable to send e-mail @yahoo
Hi, I'm French, so first excuse me for my english.
My problem is that I can not send an e-mail to @yahoo.fr.
Here is the message in log (mail.log) :
Sep 23 10:10:31 jeremydevos postfix/smtp: 93487411BA: to=<firstname.lastname@example.org>, relay=mx-eu.mail.am0.yahoodns.net[18.104.22.168]:25, delay=0.4, delays=0.01/0.04/0.13/0.22, dsn=4.7.1, status=deferred (host mx-eu.mail.am0.yahoodns.net[22.214.171.124] said: 421 4.7.1 [TS03] All messages from 126.96.36.199 will be permanently deferred; Retrying will NOT succeed. See http://postmaster.yahoo.com/421-ts03.html (in reply to MAIL FROM command)).
With MXTOOLBOX everything is OK :
SMTP Banner Check OK - 188.8.131.52 resolves to jeremydevos.com SMTP Reverse DNS Mismatch OK - Reverse DNS matches SMTP Banner SMTP TLS OK - Supports TLS. SMTP Connection Time 0.905 seconds - Good on Connection time SMTP Open Relay OK - Not an open relay. SMTP Transaction Time 3.245 seconds - Good on Transaction Time
Thank you for your help
