$myhostname and localhost.$mydomain should go into $mydestination, not
into $relay_domains. You can forward all mail to valid local addresses
to your internal host via entries in $alias_maps.

I don't think [a.b.c.d] is valid syntax for IPv4 addresses in
$mynetworks. Lose the square brackets.

You may want to use a more "speaking" name for your relay domains (like,
/etc/postfix/relay_domains ;).

In your config snippet from server A, the parameter $relay_transport
doesn't contain the IP address of server B, but the FQDN of server A.
Unless you mis-obfuscated the parameter value you need to correct that
line.

See above.

Expected, since you configured $myhostname as a relay domain.

# Server A
mydestination = $myhostname, localhost.$mydomain, localhost
relay_domains = /etc/postfix/relay_domains
alias_maps = hash:/etc/aliases
local_recipient_maps = $alias_maps
relay_recipient_maps = hash:/etc/postfix/relay_recipients

The postconf man-page [1] isn't too clear about this, but I think you
need to specify full addresses (us...@example.com OK). I have a script
somewhere that will generate a list of valid recipients from various
(file-based) recipient and domain lists. If I manage to unearth it after
I get home tonight, I'll post it here.
