Imap connection failed RoundCube

Hello,
I can't connect to my new mail through ThunderBird and RoundCube.
In RoundCube I IMAP connection error.

What should I do? Thanks

 

Hi PetrCZE,
which error do you see in the logs? - Did you change something or is this a fresh installation?
Could you paste the error here?
Because without logs or errors it is quite impossible to find the error...
Best regards,
piccolo

 

Hi man,
It is the fresh installation. Which log want you see?

 

I think it's the /var/log/mail.log could you also check if there are other mail.* files maybe something like mail.err.

 

Ok,

I changed the removed (changed) IP adresses and url adresses in logs.

 

It seems that you having trouble with your SSL Configuration:

Code:

May 27 14:48:21 hosting dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=85.163.18.100, lip=1.1.1.1, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate: SSL alert number 42, session=<D0B8oKCmsddVoxJk>
May 27 14:48:35 hosting dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=85.163.18.100, lip=1.1.1.1, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate: SSL alert number 42, session=<goxUoaCmstdVoxJk>

Witch certificate is configured in /etc/dovecot.conf ?

 

There is part of dovecot conf. https://hastebin.com/ucanunolix.makefile

I wanna set Let's encrypt. Can it solve my problem?

 

This two lines should look at your letsencrypt folder:

Code:

ssl_cert = </etc/postfix/smtpd.cert
ssl_key = </etc/postfix/smtpd.key

So that they look something like this:

Code:

ssl_cert = /etc/letsencrypt/live/<yourdomain.tld>/cert.pem
ssl_key = /etc/letsencrypt/live/<yourdomain.tld>/privkey.pem

Remember that you need to get the domain name you're using (for example: mail.yourdomain.tld) has to be part of the certificate.

 

Now I am getting this warning (URL in log changed)

Code:

May 27 17:20:02 hosting postfix/smtpd[1302]: warning: No certs for key at index 1 in /etc/letsencrypt/live/mail.example.com/privkey.pem
May 27 17:20:02 hosting postfix/smtpd[1302]: warning: error loading private keys and certificates from: /etc/letsencrypt/live/mail.example.com/privkey$
M

and this error

Code:

hosting dovecot: imap([email protected]): Error: Invalid settings in userdb: userdb returned 0 as uid

 

It looks like that the certificate files don't exist. Does this folder /etc/letsencrypt/live/mail.example.com/ exist and are there the needed files?
Did you create the [email protected] mailbox?

 

There are certs in LetsEncrypt live folder.
Yep, I created the [email protected] before this post.

 

This thread is in ISPConfig 2 forum. Is it really the case you are using that old version of ISPConfig Panel?
If not: https://www.howtoforge.com/community/threads/please-read-before-posting.58408/

 

Could you provide the following:

Code:

ls -la /etc/letsencrypt/live/mail.example.com/

and a snippet of your dovecot.conf

 

Ugh, sorry. I use the newest ISPConfig.

Btw, in read before... There isnt answer to my problem

 

Hi PetrCZE,
after the ssl_key = there is a < missing.
Please add this in the line.

 

Added, but still getting this warning.

Code:

May 28 22:46:49 hosting postfix/smtpd[1006]: warning: No certs for key at index 1 in /etc/letsencrypt/live/mail.example.xyz/privkey.pem
May 28 22:46:49 hosting postfix/smtpd[1006]: warning: error loading private keys and certificates from: /etc/letsencrypt/live/mail.example.xyz/privkey.pem: disabling TLS support

Thanks.
