smtpd_sasl_authenticated_header = yes
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination

Then 'create /etc/postfix/sasl_passwd' and add these lines
smtp.yourisp.tld user@yourisp.tld:Password

If your ISPs SMTP server doesn't require authentification than you won't need to add 'smtp_sasl_password_maps .....' line and won't have to create 'sasl_passwd' file.

Hope this helps you.
The only problem is if you do this then your ISP will get totally ticked off at you when his IP's get blacklisted and then you really have a problem.

Is there any mechanism in ispConfig mail system that can activiated if its sees more then x emails per minute it then shoots an email to admin to warm them to take a closer look?

Do you know how can I give advise to yahoo and gmail about the situation, clarify that it has been fixed, and get all mails again to inbox?

If there is no solution to this, maybe I will have to use a different IP...
I have exactly the same problem.

Mails sended from my mail server were arriving OK to gmail inbox (even with no SPF nor DKIM records).

One account was sending spam for 2 days. We solved it but since then (1 month ago) our mails always arrive at gmail spam folder.
My senderscore was about 90, it go down to 50 and now is 75.
  • According to mxtoolbox im not on any blacklist
  • Reverse DNS are OK
  • SPF record OK (now, I didn't have it before)
  • DKIM record OK (now, I didn't have it before)
  • DMARC record OK (now, I didn't have it before)
  • I fill this form to gmail but i have no response
This is the header of a mail that goes to gmail spam (I changed mail accounts and IP for privacy reasons). It seems everything is OK:
