Dear List
Has anyone else experienced this problem? According to our customer, it occurred a couple of times in the last days:
Sender and Destinations are the same in all examples:
Our customer is sending an email to bluewin:
Jan 23 13:32:42 obelix postfix-submit.obelix/smtp[28721 C5015C0CE5: to=****@bluewin.ch, relay=mxbw.lb.bluewin.ch[195.186.120.50]:25, delay=57, delays=1.6/0.01/44/11, dsn=2.0.0, status=sent (250 2.0.0 mHh5gTobfzOqbmHhngLDSm mail accepted for delivery)
Bluewin Customer replies:

Our customer replies:
Jan 23 17:24:38 obelix postfix-submit.obelix/smtp[12583 D0AE7C10EE: to=****@bluewin.ch, relay=mxbw.lb.bluewin.ch[195.186.120.50]:25, delay=101, delays=0.27/0.01/66/35, dsn=5.1.1, status=bounced (host mxbw.lb.bluewin.ch[195.186.120.50] said: 550 5.1.1 *****@bluewin.ch recipient rejected, address unknown (in reply to RCPT TO command))
Same IP Address of same bluewin server as before, not replies the destination does not exist. I can assure you, it is the same address as before.
Our customer tries again:
Jan 23 17:32:23 obelix postfix-submit.obelix/smtp[26676 C9470C1271: to=*****@bluewin.ch, relay=mxbw.lb.bluewin.ch[195.186.227.50]:25, delay=3, delays=0.24/0.02/0.59/2.1, dsn=2.0.0, status=sent (250 2.0.0 mJApg3d9Gp4S3mJAqgsUex mail accepted for delivery)
Now the email is getting through!

Hi Benoit
Be Careful mxbw.lb.bluewin.ch seems to be an entry wich is load balanced with different A Records . I've got a different IP after the TTL expired. So you are ending up on different server on the bluewin site.
maybe a server in the cluster which has a specific problem, just a guess.
Try telnet to the different server and if you can find the specific server -> then try to contact the mailmaster :-)

Benoit,
There was a problem @ Swisscom - it might be that your issues could have been related to this. Should be solved. If this still happens tell me, I would try to gather more details on specific errors.
greetings
