ImapSync VS Mailcow

You see this https://imapsync.lamiral.info/ ? It's only for mails but it's a great solution.

I've had to do large email migrations before and honestly, imapsync is the way to go - https://github.com/imapsync/imapsync

Do your parents have a domain, or are they just using the provider's domain? I've set up my 1522+ to backup our mail accounts using MailPlus on the Synology, and IMAPSYC running on my lab server. But it's backup only, not archiving. That technology could be used to get to your desired state, but there's some work involved to make a secure connection from the internet to your Synology possible, sync/archive the mail, configure you parent's devices to find your device, etc.

Check out imapsync (https://imapsync.lamiral.info/) - I am using it since years and migrated tousands of mailboxes without any problems.

Check https://github.com/imapsync/imapsync

I would use https://imapsync.lamiral.info/ for email and sure there is another tool for contacts and calenders.

There are two solutions for this 1. Using a tool called imap-sync to sync all your emails (it has a great incremental sync). You can run it periodically via cron 2. Using the same or similar tool and export to a database.

If you want to sync from one IMAP server directly to another, there's also the very popular imapsync: https://github.com/imapsync/imapsync

Have a look at imapsync. Source: former web hosting sysadmin. Used this many times to move email.

I've been running mailcow [1] on a Hetzner cloud server for a few years and am pretty happy with it.

I have been searching for a self-hosted suite similar to Google Worksuite. I found the following: 1. Mailcow - https://mailcow.email/

Yes, I switched to mailcow (https://mailcow.email) and installed Roundcube via the excellent tutorial (https://docs.mailcow.email/third_party/roundcube/third_party-roundcube).

I've heard good things about mailcow

You can self host email if you really want to, but it's really more trouble than it's worth. If you do self host, you have to worry about the consequences of missed emails if your server or Internet ever goes down, and you'll have to use someone else's SMTP server if you don't want your emails to go directly to spam. The cheapest good SMTP server is Amazon SES, which I believe is $0.10 per 10k emails. I've been looking into mailcow for self hosting an email server and it seems the best way to go.

However, https://mailcow.email/ is the ONLY exclusion I make for that. As it's an all in one docker managed solution. Where the only things you have to worry about is the reputation of your mailing IP.

But its probably easier to use a dockerized container with all the mail stuff integrated and pre-setup like: https://mailcow.email/

If you're looking for a full solution that I haven't tried (due to resources) try: MailCow. Good luck.
