How can I get a save a copy of every email I send?

Can you clarify what your asking. Every email you send is normally moved to sent mail folder. Is this not working for you, or are you asking about saving emails outwith the app?

Hi Platform34, I've realised what's happened. I was trying to find a copy of an email I sent at the beginning of January by searching and couldn't find it, but didn't realise I only had emails for the last 7 days in Sent, presumably because I uninstalled the app then to try to sort the repeated rejected email message. I assume the older ones are lost forever? I exported the details before uninstalling, then imported the file, but Send doesn't seem to have come over.

Thanks for clarifying.

If you're using an Imap connection, those emails should exist on the server's sent mail folder. Try checking via your webmail. If found there, check sync is enabled on your phone's sent mail folder.

I'm using POP, as it's all Zen Internet offers. I've still got the export file, but assume importing that, at best, would wipe my Sent emails for the last week and at worst (if the exported file doesn't contain my sent emails) would leave my with nothing in the Sent folder? I can't find any sync settings anywhere.

Only configuration data is exported/imported by the app. There's no backup and restore function for email data. Unfortunately your sent emails were deleted during the re-install.

Folder sync is only applicable to imap connections.

If I'd known that, I wouldn't have done the reinstall, which, incidentally, didn't help with the problem.
