I have a Raspberry Pi with Raspian installed on it and I am experiencing troubles sending out emails.
I have installed SSMTP and usually inside my scripts I'm sending out emails to notify me when a job is completed:
echo "$(date) Job completed" | mail -s "My subject" firstname.lastname@example.org
Everything was working fine until a couple of months ago, when I stopped receiving emails. I tried to manually launch the script and I receive this error:
send-mail: 550 Your authenticating ID must match your sending address.
I suspect there's something wrong in my SSMTP configuration, that at the beginning my email provider wasn't checking and now it's not working.
Here you can find my
# # Config file for sSMTP sendmail # # The person who gets all mail for userids < 1000 # Make this empty to disable rewriting. root=postmaster # The place where the mail goes. The actual machine name is required no # MX records are consulted. Commonly mailhosts are named mail.domain.com mailhub=mail # Where will the mail seem to come from? #rewriteDomain= # The full hostname hostname=raspberrypi # Are users allowed to set their own From: address? # YES - Allow the user to specify their own From: address # NO - Use the system generated From: address FromLineOverride=YES AuthUser=myUser AuthPass=myPassword mailhub=mysite.smtp.com:587 UseSTARTTLS=YES
I think there's something wrong, but I'm not a sysadmin and I don't have so much experience with mail services, any suggestions?
