I use sendmail on solaris

I want a secure configuration so i use TLS 1.2 and RunAsUser configured with user smmsp.

Permission are correct and tls works fine.

But when i run email give me this error

only super-user can use -l option

I "solved" using

chmod u+s mail.local

,but honestly i dislike this solution.

Someone know a better solution for this problem?

  • smmsp is usually for the MSP (configured by submit.cf). Did you change the user in sendmail.cf as well? – thrig Feb 7 '17 at 22:54
  • sure, RunAsUser configured with user smmsp.I have to use another user? – elbarna Feb 8 '17 at 0:18
  • Without root you'll need to do the setuid bit on the local mailer, or perhaps use a different local mailer protocol (LMTP?) to avoid that suid bit problem. – thrig Feb 8 '17 at 14:46
