Thanks for responses.
None of my servers is sending spam since Sunday.
I've sent the form. It states it can take at least 2 weeks for changes
(if any) to propagate.
In Google postmaster tools I can see one more thing that worries me. It
shows "Email content is possibly spammy" as 100% for March 19th.
Best,
Pawel

If the phishing issue has been resolved and you’re sure you’re not
sending phishing any longer you can use this form
(https://support.google.com/mail/contact/gmail_bulk_sender_escalation)
to get the reputation reset for that domain.
Don’t mess around trying to get delisted from random blocklists that
aren’t affecting your email delivery.

Actually MX is at 150.254.201.4 (mail.ifmpan.poznan.pl), however
150.254.201.17 also is sending emails (mostly local).
Unfortunately there is also a problem with whois
database: <mail.ifmpan.poznan.pl <https://matrix.spfbl.net/en/
mail.ifmpan.poznan.pl>> non-compliance domain.
For poznan.pl there is whois registry which is not very simple to
find (https://domeny.poznan.pl/domeny/app/index.php). I'm not aware
of any method to place whois record in public registry for
ifmpan.poznan.pl domain.
Also, I can send e-mails to @gmail.com using the same mail servers
but different domain, so the problem is definitely with the domain
not IPs.

There is one listing for that IP and the listing page for that
blocklist says: A domain is considered non-compliant when the WHOIS
search result for that domain does not contain the email address of
the domain owner. Update the registration data and remove privacy
protection for this domain in WHOIS and wait one hour for the
cached result of this WHOIS query to expire.
Which listings are you seeing that you think Google is using?

In my experience, Google uses common RBL services.
Your domain "ifmpan.poznan.pl" seems linked to the IP address
150.254.201.17. That IP address is still on some blocklists:

One of our new email accounts (in ifmpan.poznan.pl domain) has
been compromised and we've been sending spam from Mar 13 10pm for
about 24 hours.
All the other services are accepting mails now, just gmail is
blocking us. In Google postmaster tools there is not a single
user- reported spam.
On the "Compliance status" tab we meet all requirements, but we
are being treated as a subdomain of 'poznan.pl' domain which is a
regional domain, so all subdomains are primary. In this case I
don't see a way of reporting delivery issue with Google
Postmaster Tools.
