  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

New Pleskian
Im new to plesk, and this is the first VPS i have used.

When i try to send an email through my contact form on my Drupal website, it says it sent successfully, but the email never arrives.

In /var/log/mail.log I get the following...

Feb 11 12:41:11 localhost plesk sendmail[40139]: Unable to get sender domain by sender mailname
Feb 11 12:41:11 localhost plesk sendmail[40139]: handlers_stderr: SKIP

Can anyone help me resolve this please?
 
Does your mail include a "FROM" header and is the address given in the "FROM" a valid address of the collins.com domain?
Is collins.com the correct sender domain?
Does reverse DNS (PTR) of collins.com point to the IP address you are sending from?
Does collings.com have an SPF record and is the sending server included in that record so that is allowed to send mail on behalf of collins.com?
 
Ah! I found the solution.

As it was a new plesk install, under /plesk/server/preferences/ I still had localhost.localdomain

As soon as I updated this to a real domain, e.g. vps.mydomain.com then the email started working.
