You have 2 options:

- get your mailserver in the SPF records for the domains for which you 
send mail (probably not a valid option, depending on the number of 
domains and the willingness of the DNS admins for those)
- make it so that the SMTP header "mail from" is set to the original 
sender, the "From:" part is in fact only data, it is the SMTP "mail 
from" that's being checked AFAIK.

I can't check it from here, so I can't say if rewriting just the SMTP 
"mail from" is possible in mlmmj.
