Topic: 530 5.7.0 Must issue a STARTTLS command first

==== Required information ====
- iRedMail version: 0.8.7
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Linux/BSD distribution name and version: Ubuntu 14.04
- Related log if you're reporting an issue:
====

I'm trying to connect to SMTP from an application on another server. This is the error I get:  530 5.7.0 Must issue a STARTTLS command first

I tried to disable TLS (http://www.iredmail.org/forum/topic3435 … stfix.html) and I tried to use another port on my application (http://www.iredmail.org/forum/topic4796 … first.html). None of these solutions worked.

These are the actual settings on the client:

#email_delivery_method: :smtp
  #smtp_address: mail.xxx.com
  #smtp_port: 587
  #smtp_domain: mail.xxx.com
  #smtp_authentication: :login
  #smtp_user_name: "xxx@xxx.com"
  #smtp_password: "xxx"

Try commenting 'smtpd_tls_auth_only = yes' in Postfix /etc/postfix/main.cf, restart Postfix service and try again.

Is your application developed by yourself? if yes, you'd better implement TLS support for better security.

No, it isn't mine. I tried commenting the line but it didn't work... Still 530

EDIT: I solved on client side with these settings:

smtp_enable_starttls_auto: true,
smtp_openssl_verify_mode: 'none'

Thank you, you can lock the thread wink
