I can give you some pointers, but not a full solution. Examples
here are totally untested, beware of typos or syntax errors. But I
think the general idea is correct.

The obvious way to enforce this is to use a separate domain, eg.
sms.sebbe.eu. Don't list this domain in mydestination or virtual_
alias or virtual_mailbox _domains, and define relay_domains empty
"relay_domains ="

Use a transport_maps entry to pipe all {DIGITS}@sms.sebbe.eu to a
script.
# main.cf
smsq_destination_recipient_limit = 1
transport_maps = pcre:/etc/postfix/sms_transport.pcre
# sms_transport.pcre
# (a more sophisticated expression would check for a
# properly formed phone number)
/^[0-9]+@sms\.sebbe\.eu$/ smsq:
/@sms\.sebbe\.eu$/ error:must be numeric
define the smsq transport in master.cf
smsq unix - n n - - pipe
flags=X user=sms arv=/path/to/custom-script ${user}
Postfix will pipe the message (headers+body) to custom-script. The
script will need to decide which part is the body and send it to arg
$1, which will be the number.
Your job is to write a little custom script to interface between
postfix/pipe and smsq.
