When sending mail with ssmtp-2.60.3 the from adress is either the user@host or what has been set in rewriteDomain even if FromLineOverride is set to YES. Reproducible: Always Steps to Reproduce:
This is most likely an upstream problem... but... If you remove the rewriteDomain that applies... does the FromLineOverride work properly then?
No, that does not work either. I'll fill out a bugreport upstream.
Did you ever get a response from the upstream author? I have another bug here about ssmtp and ssl which requires upstream attention as well. bug #25071 ;
No, not a word :-/
2.6.0.4 fixes this. Closing.
