I need to trigger a python script every time an email is received by my webserver on a specific account. I will also need the email to be passed to the script as an argument. My webserver is using Dovecot. How do I go about doing this?

I recommend you have a look at Twisted and specifically its
IMAP
andPOP
protocols and client modules.As an example:
From here you need to just call your Python script in a subprocess when you detect a new email from your IMAP folder that you're checking... Here you could also use Twisted's Process handling as documented here: https://twistedmatrix.com/documents/13.0.0/core/howto/process.html
Good luck!
IMAP server may notify you about new messages if it supports IDLE command. If it doesn't support it then you could poll the inbox periodically using
imaplib
from stdlib (code example to retrieve messages from a time period).imaplib
doesn't support IDLE command but it could be easily added e.g.,imapidle
