I want to thank you all for the support so far. This is a summary what I've done and everything seems to function properly for now at least, except for the BIND issue...
I made a backup, removed and reinstalled only Postfix, since the only change I made to Dovecot I have reverted it and did not see a reason to uninstall/install it.
Removed the wildcard domain for domain1.com and assigned the webmail.domain1.com Plesk assigned Lets Encrypt cert. Changed all the mails to go through plesk.domain1.com and it's working fine.
The PHP error disappeared as soon as I assigned a domain/website to the Plesk OS vendor which is 8.0.27, after that I reassigned the 8.0.30 version to the site and the error is gone.
The bind issue is as following...
