Hello,
Since a few weeks, we've a problem when we send e-mail to MTA of Yahoo (yahoo.com or yahoo.fr) The log in our postfix server are:
Jan 25 09:27:37 emailfrontal1 postfix/error[12384]: 19128F857F: to=patrickjallut@yahoo.fr, relay=none, delay=164344, delays=164344/0/0/0.03, dsn=4.4.2, status=deferred (delivery temporarily suspended: lost connection with mx-eu.mail.am0.yahoodns.net[77.238.184.241] while sending end of data -- message may be sent more than once) Jan 25 09:28:00 emailfrontal1 postfix/smtp[12670]: DAC59F88F9: to=bzwahlenmattei@yahoo.com, relay=mta5.am0.yahoodns.net[66.94.237.139]:25, delay=260738, delays=260715/0.01/12/11, dsn=4.4.2, status=deferred (lost connection with mta5.am0.yahoodns.net[66.94.237.139] while sending end of data -- message may be sent more than once)
When we try a telnet connection it works but the sessions is closed after 5 sec:
telnet mx-eu.mail.am0.yahoodns.net 25 Trying 77.238.184.241... Connected to mx-eu.mail.am0.yahoodns.net (77.238.184.241). Escape character is '^]'. 220 *********************************************************
We don't see any packet loss between yahoo and us.
Is anyone have seen this problem? Can someone from Yahoo contact me offlist?
Thanks for your help. Regards Jonathan -- Jonathan Jeanneret IP Systems Engineer Service Industriels Lausanne Citycable - www.citycable.ch jonathan.jeanneret@citycable.ch
