[SOLVED] Problem to send mails from inside Projeqtor

Hello,
This is a problem that appeared after migrating Projeqtor from an old Debian 9 to a Debian 12 (PhP 7.3 to 8.2)
Everything about sending mails (sending invitaations, sending project to someone, etc...) worked on the old one
Now, on the new server, projeqtor works but not the mail sending part

Here is the error log when we try to use it

2024-04-23 19:53:09.150 ***** ERROR ***** [V11.1.3] ERROR *****

Could i have a hand on resolving this ?

Thanks

hello,

We have found the problem on our side
like the php extension "Curl", sendmail is not installed by Projeqtor

After simply installing sendmail on debian, the mail function of our migrated Projeqtor worked again

"aptitude install sendmail"

Thank you again
