Not sure if that was the clearest explanation of your problem,
here's how I interpreted it thus:
Server 1 relays mail addressed to B.com to Server 2.
Server 2 is to deliver mail for A at B.com to user ted.
I'm assuming the first part is working. I'm also assuming
the email address does not change between Servers 1
and 2- i.e. that Server 1 sends the mail to Server 2 maintaining
the address A at B.com, and not changing it to something like
A at Server2.B.com.

Yeah, that'll never work - the LHS of the aliases table cannot
contain a domain part. The aliases file operates on a username
level, and is only invoked during local delivery.
There are a number of ways to achieve what you want, depending on
whether you're handling one or many domains, and whether Server B
is meant to handle all mail for B.com, or just mail sent to
A at B.com. From my guess, this is what you want:
Tell Server 2 to deliver mail addressed for B.com locally.
If Server 2's hostname is server2.B.com, then by default sendmail
will only accept mail addressed to A at server2.B.com. Thus we need
to tell it that it should accept mail addressed
This is done by adding B.com to the local-host-names file on
Server 2. The exact name of this file can vary depending on
distribution, look for "confCW_FILE" in your.mc file, or"Fw-o" in
your.cf file. Add the following line to the file:
Now mail addressed to A at B.com will be delivered to local user A.
The aliases table can then be used to map local user A to another
user as follows:
There are many ways to achieve the same thing, this may not be
the best solution; it depends how you want your servers to
For example, if Server 2 also accepted mail for C.com and
D.example, then the configuration I just gave you would
result in mail for A at B.com, A at C.com, and A at D.example all being
delivered to ted, which may not be what you actually want.
