No need to hack code. Just set the logindomain as a hidden form variable;
replace

[#h#]

with something like

<input type="hidden" name="logindomain" value="example.com">

in login.html / expired.html / invalid.html

I would guess a null pointer error (you haven't initialised the environment
variable before starting sqwebmaild, or passed it from sqwebmail)

Correct. It only sends certain environment variables.

If you're going to hack code, and you know how to program in C, then it's
easy to find.
