Hi,

Running:

• Dovecot 1.0 rc15
• Debian Sarge Linux

Using Maildir and IMAP over SSL.

When trying to delete a lot of mail (> 5000-6000 messages) in some folder, using Mozilla Thunderbird (1.5.0.7) on Ubuntu, I often experience "Connection to server <hostname> timed out." Any suggestions on how to fix this problem?

"Empty Trash" seem to work fine, so I guess this is related to moving a lot of mail from one folder to another (Thrash)?

I have exactly the same problem here. Solaris 10, dovecot 1.0rc2, maildir, maildir space on a netapp filer mounted via NFS, Thunderbird 1.5.7

I think in my case the filesystem is to slow. Could that be?

On my system I'm not mounting filesystem via NFS.

Using

Fibre Channel: LSI Logic / Symbios Logic FC919X Fibre Channel Adapter

attached directly to a

Vendor: NEXSAN Model: ATAboy(9E263CD3) Rev: A035

for the filesystem my mail is delivered to.

RAID5 on the ATAboy Generated ext3 filesystem using

• stride=16
• dir_index Mounting ext3 using data=writeback.

Can anyone pls test, if dovecot behaves the same on your system? I think I'm not even able to delete 1000 messages in a row. I'm wondering if I have a similar problem.

Dovecot 1.0rc14 on Linux (old Gentoo setup with a 2.4.30 kernel) Maildir ext3 filesystem with dir_indexes Single user system, 500 Mhz Via CPU, 256MB RAM Client is Thunderbird 1.5.0.8, timeout set to 600 seconds

I've been trying to reorganise some old mailboxes with 20000-30000 messages, but every time I try to delete more than a few hundred messages at a time, I get - after 30-60 seconds (approx) - a "server error" message from Thunderbird.

I think the important thing to find out is what Dovecot is actually doing:

http://wiki.dovecot.org/Debugging/ProcessTracing

Start tracing before starting the deletion, then mail the whole log to me.

Dear Timo,

please see attached the log.

I created a folder called 'foobar' with exactly 2000 messages inside, then I selected All and pressed delete. As expected, Thunderbird then reported a Server Timeout.

kind regards dirk

Is there any update about this issue? We had an poweroutage this week and now my mailbox is full of about 30000 messages from the UPS's saying that the batteries will be discharged soon...

Well, looking at the strace you sent me it simply looks like the copying is slow and Thunderbird doesn't bother waiting for the 1,5 minutes that copying to Trash takes.

Set maildir_copy_with_hardlinks=yes and that should take care of it.
