Hi,
I want to setup spamassassin + clamav + postfix. Many internet guides use

don't want to install Amavisd unless it's really recommended. So would

setup work well without using Amavisd? Would you recommend using Amavisd?
Thank you,

I use it without amavisd, and works fine. I have different installations,
- integrated via using postfix/spamass-milter
- integrated via postfix/maildrop
Those have differences, and I have different requiremens for each
installation and those do it fine.
However, amavisd. It links to SpamAssasin by using it as an add-on
library. It does not need spamd up, amavisd is the daemon itself. I think
SpamAssassin + amavisd memory requirement does not differ much from using
plain SpamAssassin. I have not verified this, but this is my
understanding.
I use a combination with Postfix and spampd as a policy daemon.
In this setup the policy daemon is called in real time during the SMTP
transaction, and the incoming mail message which exhibits a SA score above a
certain value is rejected at the end of DATA.
My installation runs without any incident since 2 or 3 years on boxes with
512M RAM. But the message volume is not high, no more than 10'000 ~ 20'000
messages a day, including rejected spam.
See this information regarding spampd:

I have posted a description of my setup, in French:
