• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Postfix - SMTP with SSL

CreedOne

New Pleskian
Hi,

I have problem with SMTP on Plesk v12.5.30_build1205150826.19 os_CentOS 6.

SMTP, port 465 SSL + "My outgoing (SMTP)requires authentication"

Nov 30 14:56:14 srv1 postfix/smtpd[20199]: warning: SASL authentication failure: realm changed: authentication aborted
Nov 30 14:56:14 srv1 postfix/smtpd[20199]: warning: .....[XXX.XXX.XXX.XXX]: SASL DIGEST-MD5 authentication failed: authentication failure
Nov 30 14:56:14 srv1 postfix/smtpd[20199]: lost connection after AUTH from .....[XXX.XXX.XXX.]

SMTP, port 465 SSL - OK
