How to handle multiple e-mail accounts?

[Nid01]

Hi,
does piler support multiple e-mail accounts?
I for example have two gmail and one web.de account.

I'd like to migrate my e-mail archive from Thunderbird to piler for the reason to be able to access archived e-mails remotely.
Until now I archived e-mails to lokal archive via Thunderbird on my Home Server and the Thunderbird docker is to buggy for me as a remote access solution, so I want to try piler.

The setup of piler via portainers docker compose doesn't really work so I want to make sure, that I'm on the right track choosing piler, before I try to attempt the CLI-way with docker compose.

So does piler support multple IMAP Servers and e-mail accounts, so it can collect the e-mails from my two gmail and my web.de account?
Does it work with gmail and web.de or only with custom/self hosted domains and for example with mailcow?
Has anyone experience with BCC of incoming messages to piler via Thunderbird?
Mailcow for example allows that, but that seems to be a SMTP-Server- or Mailcow-only feature?
Is there another way, how I get my in Thunderbird archived e-mails into piler and future incoming and sent e-mail from my e-mail accounts into piler too?

My long term goal would be to completely transition to a europe based mail provider, since I'm rather unsure about hosting my own mail server and domain due to the necessary maintenance and archive e-mails locally to avoid provides mailbox storage bottlenecks.

Hi,

I can only answer some of your questions: You can configure multiple pop3/imap accounts on different servers. Should work with gmail and web.de.

Thanks for the tip.
I was able to get piler running via portainer and docker compose and found the import section where it seems I can add multiple mail inboxes.
I got there after I found and tested open archiver so I'll see which of both I will keep using.

Hello, piler supports any number of email accounts. The usual method to acquire emails is to use smtp journaling or bcc method. I assume that it's not available for your 3 mailboxes, so you can still use imap imports. The trick is to get only the latest emails after the initial mass import using 'SINCE ' imap filter, so in theory it can be down.

If you configure Thunderbird to automatically send a BCC email for each sent email to the archive, it should work. Though the imap pull could also handle that as well.

A tip for moving to a European mail provider (I assume you have your own domain name): if possible pick a provider that supports the above mentioned smtp journaling.

I currently do not own a domain, but I will look into that.
I was able to add my mail accounts but the imap fetch behaves strange

It ran the whole day till now.
I guess I have caused the 2068/234 for web.de by importing the mails via mbox while it was taking its time to count up the total and staying at 0 imported by fetching mails via imap.
Now the gmail imap is very slowly counting up the total count even though I did a mbox import before it start the imap fetch. 🤔
