Zimbra 8.8.11.GA Not Encrypted Outgoing SMTP Authentication

Post by edxz101 »

Hi, I've been using Zimbra for a long time (difrerent versions), but in this occation we have a problem with Outgoing SMTP Authentication. All my message outgoing not been encrypted, when by default this funtion it should be enabled.

Is someone with the same problem? Will I have installed something wrong?

** Release 8.8.11.GA.3737.UBUNTU16.64 UBUNTU16_64 FOSS edition, Patch 8.8.11_P4.

Greetings to all!

Hi, I finding this en my mail.log "enabling PIX workarounds: disable_esmtp delay_dotcrlf", investigate then, apparently it would be an inspection SMTP of the Firewall. Keep investigating...
