Move mbox Calmail

Moving mailboxes to Calmail

First, you must have a calmail account, with a valid password.

Your old mail (on mail.math.berkeley.edu) is still available via IMAP, and the new server (calmail.berkeley.edu) is also running IMAP. There is a good chance that you'll be able to move your old mail to your new calmail account simply by copying from within your mail client.

In the case where there is some problem with the old mail folder (e.g. the size is too large), you can use unix command line tools to manipulate the folders.

On Solaris, there is a program called movemail which will do the job.

On blue2 (FreeBSD) and on login.math, the functionally equivalent command is called mbox2imap. As an example, if your login name is james, and you want to move your mail spool (/var/mail/james) to the INBOX folder on your new calmail account, the command syntax is

mbox2imap -u james@math.berkeley.edu -s calmail.berkeley.edu /var/mail/james

If you want to upload to a folder other than MBOX, use the "-i" option to give it a name - e.g. to upload OLDMBOX to a folder on calmail name NEWMBOX

mbox2imap -i NEWMBOX -u james@math.berkeley.edu -s calmail.berkeley.edu OLDMBOX

(Note that the mailbox must already exist on the remote server, or mbox2imap will fail.)
