If the password contains # or ; you have to wrap it with triple quotes. Ex “”“#password;”“”

password =
cert_file =
key_file =
skip_verify = true
from_address = noreply@xxxxxx.com
from_name = Grafana
ehlo_identity =
startTLS_policy =

hello
i changed nothing in my config file,
i tried with version 11.2.5 => not ok
i tried with version 11.1.12 => OK
only me have this problem ?

good week

if you are using gmail account then you need to create app password for authentication then use it in grafana.ini file.


and then copy code

and then restart you grafana.

hi
thanks for your answering
but i use mailing with private smtp serveur and ,as i writed ,my configuration works with grafana v10.3 without user and password .
new question :
what is the difference between v10.3 (sending ok) and version > 11.1.x (sending No-ok) for sending mail without information for user and password in SMTP parameters ?

hi

i think that a problem is when the configuration smtp is without «user » and without « password » ; before v11.x that worked

thanks for help….

I could not find any changes in related code between those two versions you mentioned. Can you find the first version where it stopped working for you. For example, if 11.1.12 works, does 11.1.13 still work? Does 11.2.0 work?

hello
thanks to answer for my bug
i do a new tests with different version of grafana OSS and result are :
version under v10.4.17 => ok
version 10.4.17 and after => nok
the mystery is between v10.4.16 and v10.4.17 !!??

but i tried again v11.1.12 and v11.1.13 then sending email work (as the post of 7 mars 2025) !!!
so i wish you find something …
Best regards

Hello,

In my case last working version is 11.2.8.

After upgrading to 11.2.9 it started to raise timeout error.

Strange thing is that for 11.2.9 test email was successfully delivered, but only once. Now when I’m trying i get error every time.

I’ve just checked with 11.2.8 once again a few times and test messages are delivered without any problems.

Thanks !

hello ged

i am « happy » i’m not the only one with this strange problem ….

let’s wait for the rest
