Use an alias ? What do you mean ? "luser_relay=sms | mycommand " ? Or what
? Please give me an example.

That's the problem. The daemon is too fast and takes the first 15-20 bytos
from the whole mail only. That's why we need saving and individual files.

That's the only thing what the machine is serving.

I dunno. I will ask the programmer. But I suspect that part of the job
would be his.
