Greetings:

I'm sorry if this issue has been discussed before but i couldn't find any help. Today during the morning, our company's mailgateway was rejecting all the incoming e-mail, only accepting internal e-mail. Taking a look at tracking center, I found this (i tried to send an e-mail from a yahoo account):

Jul 8 11:02:39 smtpd connect from web110310.mail.gq1.yahoo.com[ip-address]
Jul 8 11:02:50 smtpd warning: 210.8.195.67.list.dsbl.org: RBL lookup error: Host or domain name not
found. Name service error for name=210.8.195.67.list.dsbl.org type=A: Host not
found, try again
Jul 8 11:03:00 smtpd NOQUEUE: reject: RCPT from web110310.mail.gq1.yahoo.com[ip-address]: 554
5.7.1 Service unavailable; Client host [ip-address] blocked using
sbl-xbl.spamhaus.org; from=<random-sender@yahoo.com> to=random-recipient@myconpanydomain.com
proto=SMTP helo=<web110310.mail.gq1.yahoo.com>
Jul 8 11:03:01 smtpd disconnect from web110310.mail.gq1.yahoo.com[ip-address]

So, i checked that ip-address at spamhaus.org by making a query trough the web interface:
ip-address is not listed in the SBL
ip-address is not listed in the PBL
ip-address is not listed in the XBL

I had the same problem with other domains.
When the mailgateway blocks an e-mail it shows a link to the query used, but this is not the case.

I've restarted the server and now everything looks fine, but i'm afraid of this happening again (users didn't receive their e-mails this morning).

Thanks in advance.
