Sorry if this is a bit off topic but I'm hoping list members here might have some ideas.
Aim: use ISP provided email with restricted inbox size but keep an IMAP accessible archive of emails (including 'sent' messages) on a remote server.
Scenario:
- Don't want to run my own SMTP server
- Have free ISP email with 1Gb mailbox limit and spam filtering that works well
- Have remote server with plenty of disk space
- Want to use remote server for IMAP access to archive of email to avoid 1Gb ISP mailbox limit
Options I tried:
Use ISP email via IMAP and periodically backup / archive messages to remote server with something like mbsync / isync to maildir format. Delete old messages on ISP server safe in knowledge they are backed up on my server. QUESTION: how to access those archives via IMAP (read only is OK)?
Use ISP email for sending messages only. Use Getmail / Fetchmail to move messages to remote server and run Dovecot there. I tried using Getmail to do this but couldn't figure out how to keep copies of 'Sent' and 'Draft' messages if the email client was configured to read via IMAP on one server and send via SMTP to another server.
Any thoughts on how best to achieve my aims?
Thanks, Tom.
