Decrypt a 1990s-era SunOS mail file that was encrypted with "crypt" command

I have a text file containing emails sent and received between me and an ex-girlfriend in the mid-1990s. We recently reconnected and want to have a laugh/cry at what we wrote. On my university's Sun Solaris machine I used the "crypt" command to keep the contents from prying eyes... but now that system is gone! The file is attached. The original text is almost all alphanumeric. I can also provide (1) similar unencrypted emails from around that time (so you can see the header format), (2) possible words and names in the encrypted file, and (3) a short list of the likely (alphanumeric) passwords I might have used to encrypt it. (There is software called Crypt Breakers Workbench on Github if you are starting from scratch.) Up for the challenge? You'll see some salty post-breakup exchanges if you can decrypt this historical file! (If you can decrypt this file with "brute-force" and want to prove it with your bid, please provide the first names of a few of the persons mentioned.)

Hi there, Thank you for reaching out to us with your interesting project. We understand that you have a text file containing emails exchanged between you and your ex-girlfriend in the mid-1990s. You used the "crypt" command on your university's Sun Solaris machine to encrypt the contents, but unfortunately, that system is no longer available. To help you decrypt the file and relive those memories, we would require the following information from you: 1. The attached encrypted file: This will allow us to analyze the encryption method used and devise an appropriate decryption strategy. 2. Similar unencrypted emails: Providing us with unencrypted emails from around the same time will help us understand the header format and potentially identify patterns or similarities in the encrypted file. 3. Possible words and names: Sharing any possible words or names that could be present in the encrypted file will assist us in narrowing down the decryption process. 4. Likely passwords: Please provide us with a short list of the alphanumeric passwords you might have used to encrypt the file. This will enable us to perform targeted decryption attempts. We are up for the challenge and confident in our ability to decrypt the historical file. However, due to the nature of the encryption and the need for further analysis, we cannot provide the first names of the persons mentioned as part of this initial proposal. Please note that this is a placeholder bid, and the exact price and...
