Hello everyone,

I am testing Dovecot 1.1.3 at the moment to see if I can migrate from UW-Imap(mbox) to Dovecot(maildir). Because I dont' want to influence the production server I installed Dovecot on an ununsed computer with some dummy-testusers using ssl and maildir. Installation was without any problems and everything works fine with one exception: I cannot download some attachments. If the attachment is a simple textfile or bitmap it's ok, but everything else (pdf, zip, etc. - size doesn't matter) does not work. Here is what happens:

1. I right-click on the attached file -> "save as" (using Thunderbird 2)
2. I choose a target dir (no matter if local disk or nfs)
3. the download-dialog pops up and says: "starting...."
4. nothing happens form then on

In the log file I see (lots of them for a single "attachment-download-try" until I stop Thunderbird): "dovecot: Fatal: IMAP(<username>): io_loop_handle_add: epoll_ctl(1, 1): File exists" (which file??)

I googled this message but without success. I already tried having all files on the local fs instead of nfs but it doesn't change anything. I also tried a lot of different settings (concerning locking, nfs, permissions) in the dovecot.conf. Everything else works just fine: logging in, receiving, creating folders, deleting etc...)

Im using a (very) old SuSE 9.0 installation with ext2. I put my (current) devecot.conf and the output of "dovecot -n" at the end.

As I have no idea what else to try/check: Anyone out there who has a tip what else I could check to solve this? Or even someone who had the same problem with a solution? ;o)

Thx Thomas

my current dovecot.conf:

ssl_cert_file = /etc/ssl/certs/imapd.pem ssl_key_file = /etc/ssl/certs/imapd.pem verbose_ssl = yes

login_greeting = Dovecot ready.

mail_location = maildir:~/Maildir

mmap_disable = yes fsync_disable = no mail_nfs_index = yes lock_method = dotlock

maildir_copy_with_hardlinks = yes mbox_read_locks = dotlock_try mbox_write_locks = dotlock_try

mbox_dotlock_change_timeout = 120

protocol imap { }

protocol pop3 { }

protocol lda { postmaster_address = postmaster@example.com }

auth_debug = yes auth default { mechanisms = plain passdb shadow { } userdb passwd { } user = root }

dict { }

plugin { }

Output of dovecot -n
