I’m a Python guy, so my answer to this would be "use Python" :-)
[The ReportLab
library](https://www.reportlab.com/docs/reportlab-userguide.pdf) is
extremely powerful and can be used to generate a PDF for every email or
a pdf for all emails. I've not used it myself, but I hear it's very good.
That’s the hard part really. Outside of that, you’d just use something
like this:
```python
import os
from email import policy
from email.parser import BytesParser
maildir = "/path/to/maildir"
messages = []
for mail in os.listdir(maildir):
with open(os.path.join(maildir, mail)) as f:
raw = f.read()
message = BytesParser(policy=policy.default).parsebytes(f.read())
if "some...@somedomain.com" in raw:
messages.append(message)
```
Once you've created a collection of email objects, you can use the
powers of the email module to easily parse out the bits you want. You
can take a look at some code I wrote that does just that
[here](https://github.com/UKTradeInvestment/barbara/blob/master/interactions/mail.py#L27).
Once you've parsed the message, you can then sort your list based on the
date. Something like this:
```python
messages.sort(key=lambda _: _["Date"])
```
At that point you have a sorted list of email objects which you can then
use ReportLab to generate a PDF.
Good luck :-)
