Gitea: Permission denied when using sendmail as mailer

I am having some trouble configuring gitea to use sendmail as the mailer.
Using the sendmail command from the gitea user seems to work fine.

relavent gitea config (/etc/gitea/app.ini):

[mailer]
ENABLED       = true
FROM          = gitea@mukundan.io
MAILER_TYPE   = sendmail
SENDMAIL_PATH = sendmail

Systemd logs:

$ systemctl status gitea

Also tried the following systemd override, does not seem to fix the problem:

[Service]
NoNewPrivileges=false
PrivateUsers=false
PrivateDevices=false
ProtectHome=false
ProtectSystem=false
ReadWritePaths=/

Re: Gitea: Permission denied when using sendmail as mailer

Hi,

I was having the same issue right now. I have solved it by:
- adding the gitea user to the postdrop group (allow gitea to write in /var/spool/postfix/maildrop)

gpasswd -a gitea postdrop

- override the default systemd service

systemctl edit gitea.service

then add the following:

[Service]
ReadWriteDirectories=/var/spool/postfix/maildrop

I guess it's too late for you @Mukundan314 but I hope this answer could help someone else in the futur.
