Two possible solutions I can figure out instantly:
1) use a filter to rewrite the message from the server to the client as this:
FTOCL="-sed -u -e email@example.comfirstname.lastname@example.org/"
2) or, setup SMTPGATE. It makes DeleGate work like a SMTP server rather
than a proxy, thus the greeting message is generated by DeleGate itself.
