One of my client renting a webshop. They sending mail via webshop mail servers with name webshop@domain.com and CC to info@domain.com
SFP DKIM DMARC all setting is ok working well. Time to time they add new servers to webshop system with new ip.
In that case they got: Recipient address rejected: SMTP AUTH is required  for users under this sender domain (in reply to RCPT TO command). So I add this new IP to mynetwork in main.cf
Is there any easyer way to handle this? minimal IP ranges they using (/30 /29 lot of /32) and of couse not countinusly...
User auth not possible sad

Thank you!

Just enable SMTP authentication to send email. This is the easiest and BEST solution.
