I am migrating my current self hosted IMAP mail server (hMailServer) to Google Apps.
I managed to move an account's "sent" folder to Gmail using Thunderbird drag and drop, and while it seems to keep most of the data correctly (date etc), I have 2 problems:
Some mails do not keep special characters charsets correctly, i.e. ç - they are shown correctly in thunderbird on the source server AND the destination server, but webmail (Gmail) shows them in a different charset, apparently
Some of the sent mails are listed as to "me", as if I sent the mail was sent to myself, even if that is not the case, again, this is a problem only when seeing the it in Gmail.
I suppose these problems might be related to incorrectly set headers in the original emails.
What could I try to change to fix these problems?
What application I could use to perform the migration without the above problems?
