Yes and Yes.

If you -had- the sender's public key, it wouldn't need to check a public
key server.

Import a copy of the sender's key you your keyring.

For integrating into GPG (ie, so it will auto query)?  Add the following
to ~/.gnupg/options:

# GnuPG can import a key from a HKP keyerver if one is missing
# for certain operations. Is you set this option to a keyserver
# you will be asked in such a case whether GnuPG should try to
# import the key from that server (server do syncronize with each
# others and DNS Round-Robin may give you a random server each time).
# Use "host -l pgp.net | grep www" to figure out a keyserver.
keyserver wwwkeys.eu.pgp.net

Note that http://wwwkeys.us.pgp.net/ has a web-based interface, so you
can look up a public key, save it to a file and use 'gpg --import-key < file' 
to import it.  [And note that the '--import-key' isn't really needed...
gnupg is smart enough to see that it's a key and figure out the only
thing you really can do with a key is import it....]
