Return path rewritten

Good afternoon,

We are running:
Sun Java(tm) System Messaging Server 6.3-3.01 (built Jul 12 2007; 32bit)
libimta.so 6.3-3.01 (built 20:10:10, Jul 12 2007; 32bit)
SunOS zulu.unige.ch 5.10 Generic_125100-10 sun4u sparc SUNW,Sun-Fire-V440

I am trying to debug a alias expansion problem.

On a host I have defined in the alias file:
bioveg-all:     </path/bioveg-grp.dis, \
               [BLOCKLIMIT] 300

This works fine except when there is an invalid address
in the dis file, an error message is sent to bioveg-all
because the return path is changed to bioveg-all.

On our pmdf host the error message was sent to the sender only.

Would you have an idea on this behaviour cause or
which imta test -rewrite I could do to trace 
why the from address is changed?

Thanks in advance for your help.
