Back up Foxmail to Gmail

Previously, emails were received using Foxmail, And the mailbox size was limited. Due to insufficient space, emails were not backed up on the server. My Foxmail local mail directory already has more than 2 GB, which is too space-consuming. Now I use Gmail to receive emails from my n mailboxes, so it would be nice to back up more than 2 GB old emails in local Foxmail to Gmail. This saves my hard disk space and facilitates searching for emails for unified management.

 

I found some methods for this purpose. The final solution is as follows:

1. confirm that your Gmail mailbox has enabled IMAP (configuration-> forwarding and POP/IMAP) in the configuration)

2. Upgrade Foxmail to 6.5 (the latest version I can download is 6.5 beta3) Because Foxmail supports IMAP only after this version.

3. Configure your Gmail mailbox in Foxmail. You must set it to IMAP !! You can set "Do not synchronize" for all IMAP folders so that you do not need to download emails from your current Gmail.

4. In Foxmail, select all emails under your old email account, right click-copy to-select a directory under your newly configured Gmail account.

5. OK

This process should have been smooth, but my old email has a problem:

There are a lot of emails that can be viewed in the Foxmail directory after you right-click and copy them to the Gmail directory. However, you can see some emails with "no sender or subject" in your browser.

 

By viewing the original mail information, it is found that the problematic mail has one more line in the header of the original information than other Emails: "+ OK"

It's strange, but as long as I get rid of this line, emails will be displayed normally in Gmail.

 

I have 2 GB of mail. How can I remove this line in batches?

 

Foxmail's email storage format is one directory, one directory and one file, which makes it inconvenient for me to write programs.

My method is to export the Foxmail email. eml (select "email"> "file"> "Export"> "OK"), process the EML, re-import Foxmail after processing, and reproduce "Copy to Gmail directory". OK! No problem! :)

Let's talk about the small program I wrote to remove unnecessary content from the. eml file header.

If you use NotePad to open the. eml file, you will find that it is actually a text file, and the content in it is exactly the same as the original mail information.

My problem is that the original information of my mail has one more line in the file header. I only need to write a program to traverse all the files in the directory, determine whether the first line is "+ OK". If yes, delete it. after the EML file is imported to Foxmail, it can be copied to the IMAP directory of Gmail and displayed normally in webmail.

 

The program is very simple, so there is no comment:

Gmail that supports IMAP is really cool ~
