Dear my friends.... I use OpenSuSE 11.1, KMail and DoveCot version: " sussy:/etc/ssl/certs # dovecot --version 1.1.7 ". This is the configuration of my DoveCot: " sussy:/etc/ssl/certs # dovecot -n # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.29-0.1-default i686 openSUSE 11.1 (i586) base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log protocols: imap imaps pop3 listen(default): * listen(imap): * listen(pop3): *:110 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: Dovecot of MyGoogle.Com ready. mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: debug_passwords: yes passdb: driver: pam userdb: driver: passwd ". I have created local linux user account on my Postfix+DoveCot server. I also can access the content of my mailbox from my KMail. I am so happy but once I try to send email (testing the smtp) than I realize that I can't send an email from my email client (KMail). I use this setting on my email client: 1. 'incoming mailserver' == 'outgoing mailserver' == 'mail.mygoogle.com' (pseudonome). Also username and password are all the same between incoming/outgoing mailserver, namely the local userlogin of LINUX. As the username, I put 'ricky' (but not 'ricky@mygoogle.com'). 2. smtp authentication: No encryption and plaintext. The error message on my KMail is: " Sending failed: Your SMTP server does not support The server responded: "5.7.8 Error: authentication failed: generic failure". Choose a different authentication method. The server responded: "5.7.8 Error: authentication failed: generic failure" The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.

==== Hi John, Then come this error message: " Sending failed: Your SMTP server does not support TLS. Disable TLS, if you want to connect without encryption. The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder. The following transport was used: mygoogle.com ". Because it automatically chosed the TLS. If I choese 'none' encryption with 'no smtp authentication', the error message will be: " Sending failed: Message sending failed since the following recipients were rejected by the server: feybe_k@yahoo.com (The server responded: "5.7.1 : Relay access denied") The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.

It's impossible for anyone to say without further information, but *if* your provider requires you to authenticate using a userid and a password, and *if* these are being sent in plain text, it makes sense that the connection should be using TLS to prevent others from picking up your password.

The error messages you sent strongly indicate that the receiving server required TLS, and since this could not be established, your authentication failed.

I assume that is your attempt to send an email. Notice that it is coming from an IP that does not match the IP from your domain, as far as I know. It is not coming from the intranet, but from internet, and thus, postfix should require authentication before accepting to relay that email. Read postfix documentation, the part for sasl authentication. For this part, you need to setup the "server" sasl side (the client side is needed if postfix has to authenticate to another server). /usr/share/doc/packages/postfix/html/SASL_README.html

Then, instead of using "mygoogle.com", just replace your real domain name with something "MYDOMAIN" in uppercase, so that we know you replaced it.

You probably need TLS.

I've seen a hint in his logs that tlsmgr does not exist in his configuration. That is probably the real cause of that message.
