Welcome @abdul545 Happy you are here

If you are trying to access SnappyMail admin you can trace the password here

nano /usr/local/lscp/cyberpanel/rainloop/data/_data_/_default_/admin_password.txt

If this password does not work you can reset it by following this SnappyMail Admin Access - #4 by rahmanbd

Are you using the correct credentails? Try change email password and try again

abdul545 · January 12, 2023, 10:51am

yes correct credentails

abdul545 · January 12, 2023, 10:52am

I have changed many times

abdul545 · January 12, 2023, 10:56am

@josephgodwinke Now I recently change my email pass and try to access webmail and got this error
Authentication failed
Server message: AUTHENTICATIONFAILED Authentication failed.

abdul545 · January 12, 2023, 11:00am

@josephgodwinke brother what can i do now?

josephgodwinke · January 12, 2023, 11:52am

Can you log into snappymail admin?

abdul545 · January 12, 2023, 2:26pm

yes @josephgodwinke by applying your above given commands i can do that very easily and thanks a lot for your help

josephgodwinke · January 12, 2023, 2:30pm

I want you to log into snappymail admin and go to https://SERVER_URL:8090/snappymail/?admin#/domains and select the domain you are trying to log into. Test all configs for that domain and post screenshot here

I am more so interested in SMTP test

abdul545 · January 12, 2023, 2:38pm

ok I am sending you the screenshots @josephgodwinke
oops they restrict me to post only one media

abdul545 · January 12, 2023, 2:39pm

abdul545 · January 12, 2023, 2:44pm

abdul545 · January 12, 2023, 2:48pm

I got this error when i am trying to access webmail @josephgodwinke

abdul545 · January 12, 2023, 2:51pm

now what i do @josephgodwinke

josephgodwinke · January 12, 2023, 4:11pm

Click TEST

You were running a digital ocean droplet before you changed over to Linode.

The issue looked like SMTP restrictions which we could not identify. However, DigitalOcean Droplets can have SMTP blocked due to reasons like bad firewall, built-in restrictions, spam protection.

To fix this contact Digital Ocean support to help you open the SMTP ports since setting up all-port outgoing rules the issue will still persist.
