Hello, I have some website with contact form. Unfortunately some mails from this contact form are mark as spam. How can I disable spam filtering for this contact form ? Or improve situation, what is the best way ? regards
You can whitelist that sender or IP-address. ISPConfig Interface E-mail tab | Global Filters | Postfix Whitelist. More info in ISPConfig Manual.
when you have a contact form on your website you don't know who will fill your contact form. By the way I ask about a contact form on a website hosted with Ispconfig so same server ....
Set up SMTP authentication for your form/cms on port 587 or 465, which will bypass spam scanning when delivering to local accounts. If they're marked as spam on remote servers that might help, but you may have to take other steps as well (eg. setup spf/dkim/dmarc to send a clear "approved to send" signal).
