How could I do it with postfix. Could it lock the mailbox by itself or the
programmer has to write an addititonal module to it ?

Oh, yeah. But the importance of the daemon is as follows: an e-mail
arrives from mobile phone (through sms gateway of provider). It contains a
data about something. The daemon gets it and passes it to a program which
examines it and creates an output by the data it contains which goes to
the database. That's the problem. That's kind of online business through
email/sms. Sorry if I was unclear before.

Yeah but it's important to provide fast response to the customer (it
incorporates some kind of IA) wheter we can do the delivery or not.
