Apple Mail not syncing with FastMail

Apple Mail is failing to sync with FastMail using IMAP. Most messages sync OK but some don't.

My iPad syncs OK so I reckon it has to be a problem with Mail.

If I force Rebuild the FastMail Inbox (in Apple Mail) the missing messages turn up.

Anybody got any idea what may be going wrong?

Thanks.

Try re-indexing the mailboxes. This can take awhile if you have a lot of mail.

Reindex messages For El Capitan, try looking in V3.

Reindex messages (2) See post by Linc Davis
