Re: [CentOS] Dovecot problems
I'm not sure I understand all of the consequences of just moving these folders from /home/user/mail to the new servers. So far, I seem to have things working OK with a pop, imap, and horde webmail situation for any particular account. It required using namespace, but it seems to work. Can anyone give me a little heads-up on what to expect by doing things this way? Thanks so far for all the help. steve On 2/13/2012 3:31 PM, Peter Peltonen wrote: Hi, On Mon, Feb 13, 2012 at 7:43 PM, Les Mikeselllesmikes...@gmail.com wrote: If you need to convert formats or copy between machines, there is a program called imapsync that will connect as a client to two imap servers and sync the folder structure.

Re: [CentOS] Dovecot problems
did you try doveconf -n -c dovecot.old.conf dovecot.new.conf we also use dovecot for POP as well as IMAP. we are using the maildir storage for mails (one file per one mail). no problem sofar (touch wood). suomi On 02/13/2012 01:35 PM, Steve Campbell wrote: On 2/12/2012 2:09 PM, Alexander Dalloz wrote: Am 12.02.2012 20:01, schrieb Steve Campbell: Actually, I'm having problems with pop and imap.

Re: [CentOS] Dovecot problems
Never too late for information. Here's the situation as it stands. The original server is a Centos 3 box, and the new server is a Centos 6 box. They are separate boxes and I can move mail back and forth between the without losing any email (so far). I've got pop3 and imap logging in, but only retrieving pop email, etc. on the new box. The INBOX points to where sendmail deposits it. My config right now stands at: mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u protocols = pop3 imap By switching my test account from pop to imap, I can't get emails. I'm not sure if the info in your link is pertinent yet. But now I'm wondering if I need Namespaces configured. Both pop and imap use the same INBOX (/var/spool/mail/%u) but imap doesn't seem to honor the above mail_location). So for now, I'm reading a lot more trying to discover how things aren't working.
