qmail-smtp install problem

[Tim Holzmann]

I'm getting a '_' appended to the remote destination domain name for ex. [EMAIL PROTECTED], the '.com' is '.com_', this only happens when I try to send mail from a host other than the local mail server, from the mail server the domain name is fine and the mail is sent, any suggestions, here's a log snippet..   WORKS.. @400000003ae09a3926feb444 new msg 389935 @400000003ae09a3926fefe7c info msg 389935: bytes 199 from <[EMAIL PROTECTED]> qp 2484 uid 0 @400000003ae09a392a1eff44 starting delivery 23: msg 389935 to remote [EMAIL PROTECTED] @400000003ae09a392a1f3dc4 status: local 0/10 remote 1/20 @400000003ae09a3b3867d3b4 delivery 23: success: 209.150.200.6_accepted_message./Remote_host_said:_250_<3AE0904F00000FDC>_Mail_accepted/ @400000003ae09a3b38683174 status: local 0/10 remote 0/20 @400000003ae09a3b38684ccc end msg 389935 FAILS.. @400000003ae09b2306eb2bec new msg 389935 @400000003ae09b2306eb723c info msg 389935: bytes 1320 from <[EMAIL PROTECTED]> qp 2492 uid 507 @400000003ae09b230a7bebfc starting delivery 24: msg 389935 to remote [EMAIL PROTECTED] @400000003ae09b230a7c1ec4 status: local 0/10 remote 1/20 @400000003ae09b230d26d81c delivery 24: failure: Sorry,_I_couldn't_find_any_host_named_aromasys.com?._(#5.1.2)/ @400000003ae09b230d27169c status: local 0/10 remote 0/20 @400000003ae09b2310af6e54 bounce msg 389935 qp 2494 @400000003ae09b2310b1b45c end msg 389935 The remote email address [EMAIL PROTECTED] is hosted by an external ISP...
