If I am understanding you correctly, your mydomain does not include
mail.mydomain.in, but does contain mydomain.in, and you're wondering why
mail for unlisted recipients is being accepted?

If this is correct, this isn't an amavis issue, but a postfix
configuration issue.

You either have to list your valid recipients in your
relay_recipient_maps, or unset relay_domains and remove the
relay_domains and perhaps mynetworks from the
parent_domain_matches_subdomains.

main.cf:

relay_domains =
#parent_domain_matches_subdomains =
debug_peer_list,fast_flush_domains,
permit_mx_backup_networks,
qmqpd_authorized_clients, smtpd_access_maps,
mynetworks,relay_domains

#parent_domain_matches_subdomains =
debug_peer_list,fast_flush_domains,
permit_mx_backup_networks,
qmqpd_authorized_clients, smtpd_access_maps

I don't understand "although it contains the PDF stuff"... ?
