Error: "Unable to log in at server" Thunderbird and other email programs

Thunderbird and other email programs do not detect the email, I get the error “Unable to log in at server. Probably wrong configuration, username or password”, password and mail is fine because on web mail it logs in. What could I have wrong?

Welcome @Kacper_Bredow Happy you are here

Kindly use startTLS instead of SSL/TLS

Hi, I have set startTTLS and I have the same error :frowning:

Set to autodetect make sure you have the correct username and password

At auto I can’t click done, I have it locked

Well this is not helpful. Can you access your mailbox from snappymail ?

Yes and it works I sent some test mali and it works fine

Go to https://<SERVER_URL>:8090/snappymail?admin and click on Domains → Click any domain and a modal/popup will open with IMAP, SMTP,SIEVE settings. Test those settings if they work copy what you see to thunderbird it should work. If it doesnt then it must be an ssl issue

going to “https://<SERVER_URL>:8090/snappymail?admin” I have a login panel only that the admin credentials from cyberpanel don’t work and I don’t know what to log in to

(where can I find the login details or create an admin account for snappymail?). And when it comes to server settings I have something like this in cyberpanel …8090/email/listEmails


is this useful or should I not look at it?

Copy the password you see here /usr/local/lscp/cyberpanel/rainloop/data/_data_/_default_/admin_password.txt

I have a password but question what login to use, I used admin and Admin but it doesn’t work

what is the output of checktls

if you didnot change the username in application.ini then the username is admin
