I am getting problems with sending mail to some e-mail addresses. (If I am sednding the same message from another mail server to that address then everysing works fine) The message in log file looks: delivery 50: deferral: CNAME_lookup_failed_temporarily._(#4.4.3)/
As I understand there is a problem with DNS lookup or I am wrong? Please advise what I ahve to do to solve this problem. o
