Postfix speed

I installed fedora, according to perfect installation, and postfix+amavisd+dovecot.

Now the mails are sent very slow, there is a pause 1-3 seconds between each sent.

There is no DNS problem, cashing nameserver is set.

Can somebody point me, what to change to speed up the whole process ?

The mails get scanned by amavis, so the pause is normal.

thanks for reply,

do you know how to disable amavisd, at least for sending from local domains?

I tried commenting line
#content_filter = amavis:[]:10024
in but didn't help

Also found some explanation about white listening in amavisd.conf

@whitelist_sender_maps = (['', '']);

but think nothing changed.

Can we disable amavisd for some users, their mails are free of viruses, and speed is important while sending ?

I want just to close this thread and tanks for help. Problem was not with postfix / amavisd, but with PHPMailer. We used older version, and after upgrade the problem has gone
