Exim не может отправлять сообщения на удаленные почтовые серверы

Я использую специальную сборку exim (в комплекте с afterlogic pro mailsuite) с centos5.6. Система не может отправлять сообщения на удаленные почтовые серверы, такие как yahoo или gmail, и выдает следующую ошибку:

someuser@gmail.com R=dnslookup defer (-1): host lookup did not complete

Я могу найти DNS-записи gmail.com с помощью команды dig:

    #dig mx gmail.com

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-16.P1.el5 <<>> mx gmail.com

Я запустил команду отладки с exim, и получилось так:
