[-- Attachment #1 --] Dear Sir, I'm told to post following problem to your site for an answer: I made sendmail 8.6x running on Solaris 2.4 as a mail host (pub), a dial-in NT server running Exchange (bbs) as a SMTP gateway. Everything is OK except the inbound mail to bbs. Would you advise me ?

I add on some other thing to both the /etc/hosts and DNS files, especially the reverse look-up record (PTR) for both bbs and pub. It seems working now. Anyway thanks for giving me so much help, it will be great plessure to keep touch with you. Thanks again. Best Regards.
