Vesta Control Panel - Forum

Good day!
Maybe somebody can help me? I migrate my WordPress websites to Vesta day ago, all websites working fine, but have a big problem with contact forms (Contact Form 7, Visual Form Builder). When form filled and submitted i don't see any mail in my inbox. Before haven't this problem.
Mail using "Yandex Mail for Domain", if send mail from Outlook or Web-interface then all is fine.
Maybe any ideas?

Solved: This forms use Postfix. Install. Configure. Works!

Did you install Exim4 MTA while installing VestaCP ?

If it was installed, you chose the wrong solution mate. VestaCP uses Exim4 as MTA and postfix should not be installed along with it. If the mails were not being, you should check Exim logs and fix it...
