Maximum Number of email mail boxes in Mac Mail

Hi, is there a max number of email mailboxes that Mac Mail supports? I have 20, need 25.... After adding email #19, email address #20 with not show under "All inboxes". When I send email to the last email address added (#20) it's not received by Mac Mail. When I go to Mail -> Accounts, the account is there and active (mail is toggled "on") but I can not "see" the email account in my list of emails much less being able to receive or send emails from that account. Running Ventura 13.0 and Mail 16.0 (3731.200.110.1.12). Thanks for the help.

Hi...an update. I was successful in getting 26 separate email addresses to work. Two Yahoo IMAP, one iCloud, one Comcast IMAP, three Exchange and the rest Gmails. I did have an issue where one mail showed up as installed but would not show up in Mail account lists. I deleted the account and re created it and then all was fine. I was able to add six more GMAIL accounts after. For me, the issue is solved: Deleting and recreating the email (Gmail) account solved it.
