Greetings, I'm having big issues here, hope you can help me…
Ubuntu Server 8.04, postfix 2.5.1, dovecot 1.0.10, postfixadmin (MySQL+ virtual users)…
I am trying to move e-mails from an old IMAP account to my new dovecot IMAP server accounts. The old server is EIMS (Eudora Internet Mail Server, so a sort of mbox format)… I move messages by drag 'n' dropping in Mozilla Thunderbird.
No problems with messages under 4MB size (there are huge messages, up to 25MB), but as soon as I try to move messages from 4MB and up, the connection hangs, nothing happens, the application becomes barely responsive, I have quit and re-open it to make it behave properly.
In the logs, I read (user and IPs are fake, here):
Sep 18 07:52:06 in dovecot: imap-login: Login: user=user@my-domain, method=PLAIN, rip=123.123.123.123, lip=123.123.123.123 Sep 18 07:52:06 in dovecot: IMAP(user@my-domain): Disconnected: Too many invalid IMAP commands.
Could it be a client (Thunderbird) issue? I have tried with Apple Mail 4.1, same problem, same logs.
Could it be a quota limit (googling around, I read that sometimes the error may be triggered by dovecot when exceeding the quota limit) Accout usage is actually at 1%…
Could drag 'n' drop be the wrong way to have things done? I have also downloaded the huge e-mails from EIMS to Thunderbird Local Folders, the problem arises when I try to upload, so the culprit seems to be the new "system".
I really need help at this point… any hints?
Thanks in advance for any help you will offer.
