Description

Currently, I've been unable to find a user friendly appliance that performs the function of downloading email from all my external email accounts into one local consolidated account and serving that to my LAN clients on my home network via IMAP, where I can filter on source account and instead of using Thunderbird to store the emails archived locally, I'll always have all my emails on a server residing on my Proxmox instance, accessible to all my devices on my LAN. This appliance need not perform SMTP functions and should not require a domain or even a public IP address, but rather have configuration entries at account registration to specify SMTP settings as you would in Thunderbird or similar email client. I did this years ago with Debian/Exim/Fetchmail out of the box with help of Webmin, but I've been unable to recreate the scenario due to lack of literacy in configuring mail services. I'm wondering if there's a call for this with other Home Proxmox users, as I would find it one of my most valuable appliances yet were a modern elegant solution for this to become available. Food for thought. Reply if you have similar needs or if you are embarked on a similar effort. Think the "Open Archiver" LXC container script with an IMAP server added that can only be addressed on the LAN, so no DNS records required. This allows me to still keep using my Thunderbird email client, but hosts the emails from a local server instead of going directly to the email providers site. I've seen outgoing messages handled both ways, with a redirector in the local mail server, or just by specifying the external outgoing SMTP server in the email client. Better if it were done locally, so offline operation would not lose messages, but there's some wiggle room on this requirement.

Due Diligence

• I have searched existing scripts and found no duplicates.
• I have searched existing discussions and found no duplicate requests.

The following link describes it, but an easier to setup version of same is sought, and obviously more centered around a Proxmox LXC container rather than docker would be ideal.
