blackberry mx servers blacklist of postfix server ?



We are unable from one of our servers to send mail to blackberry mailbox.

We have this from postfix log :

Jul 28 16:41:32 toto postfix/qmgr[22971]: 070762300F: to=<****@***.blackberry.com>, relay=none, delay=240528, delays=240526/1.5/0/0, dsn=4.4.2, status=deferred (delivery temporarily suspended: lost connection with mx03.bis.eu.blackberry.com[] while receiving the initial server greeting)


We have also this message from all blackberry mx servers.

We have test connection with a telenet on the port 25, but the connection is closing instantly :

$ telnet mx04.bis.eu.blackberry.com 25
Connected to mx04.bis.eu.blackberry.com.
Escape character is '^]'.
Connection closed by foreign host.



We have not this problem from other servers and this problem appeared since a few days.

Do you think there can be a blacklist of smtp servers which are sending mail to bb mailbox ?

Any help will be greatly apperciate.

Re: blackberry mx servers blacklist of postfix server ?

BIS maintains its blacklist of IP address and domains based on industry standards. If your IP and domain ratings have gone bad on anti-spam monitoring websites, and as soon as those ratings are back to normal you should be able to send mail to BB address.

Re: blackberry mx servers blacklist of postfix server ?

How long do you have to wait, with a cleared reputation, to be cleared?  We had a problem but have been clean for over a week and still can't send email to any domain with a xxx.blackberry.com address.  Is there a more proactive approach to being reinstated? A point of contact we can call or email?


Thanks for any help
