It looks like a mismatch between your dovecot and postfixadmin password ARGON2I in dovecot and are using a MD5-crypt scheme in postfixadmin. Therefore when you set the password in postfixadmin it is saving the password with a different encryption scheme to the one that dovecot is using when it verifies the password. I suggest to align them. If you change the postfixadmin setting, remember you'll have to change the existing passwords that have been stored while using a different setting to the dovecot one.
John, you magnificent soandso! That was indeed the problem. I changed PostfixAdmin to ARGON2 and everything worked. Thank you so much!
Also one other point (not sure if it's related to the multiple issues you've been posting about), but ARGON2 apparently requires a lot of virtual memory. Were you using this previously or did you change to it during the server installation you did recently?
I was using it previously. It was in the tutorial I followed.
