Outgoing mail using postfix takes long time

[Anton NG <anton221100 yahoo com>]

Hi all,

I have problem sending mail from my postfix linux with
MailScanner+ClamAv. It's very slow when sending to
other  
e-mail server like mail.yahoo.com & if recipient more
than one e-mail addresses i will receive "Undeliver
Message..."  from postfix, eventhough the mails will
be received by recipients.

thanks'

anton
