Can't connect to outgoing SMTP server (GMAIL or YAHOO)

  • Posted October 31, 2014

Hi guys. I have installed Centos 6.5. At last week all worked perfectly, but now I have a problem. I can’t connect to outgoing SMTP servers from my droplet via PHP. Have same errors, something like “Server not respond” or “SMTP server can’t authenticate”, etc. Tried to connect via SSL and TLS ports. it doesn’t works. What you can say about it?


Did you enable a firewall recently?

Same issue. My firewall have all rules for outgoing and ingoing. But, with firewall disabled is possible reproduces same problem.
