similar to: Webmail accessive Dovecot logins

Hello, I've seen this issue before, running a imap/smtp/database server on localhost and adding in a webmail interface, in this case Roundcube. In my maillog I'm seeing accessive Dovecot connections and logouts just from my own transaction of logging in, going to compose a message, sending, and logging out. I'm using Mysql as database backend and was wondering if there was something

Hai,   Im upping my servers with security setting. Now i noticed that even some sites/tools say its ok, but its really not ok.   So Im looking for the ciphers list for samba or how can i display them. and i want to set the cipher list and order like the example below. Is this possible with samba?   Anyone who can point me to the right direction?   I did google .. and i getting only

Hi Timo, reading this http://www.kuketz-blog.de/perfect-forward-secrecy-mit-apple-mail/ it looks like DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA can be forced in use with apple mail ( if no ECDHE is possible ,by missing openssl 1.x etc, seems that apple mail tries ECDHE first if fails its going to use RSA-AES128-SHA ) force soltution as tried ssl_cipher_list =

Hi Is there known advices on how to favor PFS with dovecot? In Apache, I use the following directives, with cause all modern browsers to adopt 256 bit PFS ciphers, while keeping backward compatibility with older browsers and avoiding BEAST attack: SSLProtocol all -SSLv2 SSLHonorCipherOrder On SSLCipherSuite ECDHE at STRENGTH:ECDH at STRENGTH:DH at STRENGTH:HIGH:-SSLv3-SHA1:-TLSv10

Hi, I want that dovecot uses PFS with my Apple Devices. I set the Cipher List to: ssl_cipher_list = DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!CBC:!PSK:!SRP:!DSS:!SSLv2:!RC4 I got this from here: http://www.kuketz-blog.de/perfect-forward-secrecy-mit-apple-mail/ But then my only Outlook 2010 Client won't connect. If i enable rsa-aes128-SHA again on third place

Hello! I'm attempting to get Dovecot working with MySQL user database on another machine. I can connect to the MySQL (5.7.26) instance with SSL enabled: ?mysql -h db.mrst.ee --ssl-ca=/etc/dovecot/ca.pem --ssl-cert=/etc/dovecot/client-cert.pem --ssl-key=/etc/dovecot/client-key.pem --ssl-cipher=DHE-RSA-AES256-SHA -u vmail -p However if I use the same values in dovecot-sql.conf.ext, I

I turned of ssl_cipher_list in dovecot.conf file (so it's default) but test still gives errors: Apr 27 08:55:06 serwer-1 dovecot: pop3-login: Error: SSL: Stacked error: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol Apr 27 08:55:06 serwer-1 dovecot: pop3-login: Error: SSL: Stacked error: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol Apr 27 08:55:07

Thank You for answers. But: 1. How should be properly configured ssl_cipher_list? 2. Ok, removed !TLSv1 !TLSv1.1. 3. Strange thing with ssl_protocols and ssl_cipher_list, because on older server on Ubuntu 14.04 LTS, dovecot 2.2.9 and postfix 2.11.0 these two lines looks exactly this same and no errors in mail.err file and mailes works without any problem. 4. No, currently I don't use LMTP.

Hi, To default dovecot.conf file I added (based on found documentation): ssl = required disable_plaintext_auth = yes #change default 'no' to 'yes' ssl_prefer_server_ciphers = yes ssl_options = no_compression ssl_dh_parameters_length = 2048 ssl_cipher_list =

Cipher list which You post provide better compatibility or security than those which I currently have? On older software version these cipher list works well and not generate any errors when I run Internal PCI scan test from https://cloud.tenable.com for another server. But for new server with newer software during test I got errors in mail.err. 2017-04-27 10:00 GMT+02:00 Aki Tuomi <aki.tuomi
