Hi all. The problem is with mail accounts of an ISP (wanadoo). When i send mail to any email address from wanadoo,orange,etc (all are the same ISP) the mails are returned with this error in my logs: server refused to talk to me: 550 Reverse DNS lookup failed for host XX.XXX. (port 25) I don't know if I have more problems, but I need to resolv this first. The IP address of my server is incomplete only the first and second octets appear. I think the mails are retuned because the other server receive an incomplete IP from my server. I try several combinations with "mynetwoks and mynetworks_style" in Postfix but nothing changes. Any idea. Thanks.
I made the test at http://www.ipchecking.com/. General information on XX.XXX.XX.XX: IP address: XX.XXX.XX.XX Host name: cliente-XXXXX.iberbanda.es (This is my ISP's name) Country: SPAIN SPAIN Flag RBL (Real-Time Blocking List) lookup on XX.XXX.XX.XX: SPAMCOP - (SpamCop Blocking List): Not Found SBL (Spamhaus Block List): Not Found XBL (Spamhaus eXploits Block List"): Not Found DSBL (Distributed Server Boycott List): Not Found CBL (Composite Blocking List): Not Found NJABL (Not Just Another Blocklist): Not Found SORBS (Spam and Open-Relay Blocking System): Not Found SURBL: Not Found The IP address is well in all tests. The PTR record points to my isp anyway the problem is why an incomplete ip address appear in my mail logs in the followin form XX.XXX. look, only the first and second octets. Thanks.
