You can use a host name, but MX is not taken into account.

It is up to a DNS resolver to determine what happens if a DNS name has multiple A records.

amavisd.conf-sample :

# POSTFIX, or SENDMAIL in dual-MTA setup, or EXIM V4
# (set host and port number as required; host can be specified
# as an IP address or a DNS name (A or CNAME, but MX is ignored)
#$forward_method = 'smtp:[127.0.0.1]:10025';  # where to forward checked mail
#$notify_method = $forward_method;            # where to submit notifications

If for some reason TLS is needed for passing a message from amavisd back to MTA, amavisd-new-2.6.0 can do it with a quite good transfer rate (transfer rate drops by about a factor of 2):   $tls_security_level_out = 'may';

It can also accept mail over TLS, but this is much slower (transfer speed drops by a factor of 10), so it is not something to be recommended unless really necessary:   $tls_security_level_in = 'may';
