I might instead try set sendmail=/run/setuid-programs/sendmail Your issue could probably also be solved by adding /run/setuid-programs to the PATH for system services, which Guix system does not do. (It does add /run/current-system/profile/sbin). Then you could use the relative 'sendmail' invocation. I believe the latter part is a bug in Guix System. Kind regards Felix
