Ok I finally figured it...

It was because of improper permissions for the attachments folder.... I did an strace and found this.

Once I changed the permision to the attachments folder it was alright..

I think this is a bug... it must check and fail and report a proper error message.. instead of this cryptic error...

here is the strace output...

Hello list,

I have a dovecot 2.2.5 instance configured to use mdbox as mailbox format. I configured to use separate storage attachments and use SIS.. (doveconf -n below)

I get this error

Sep 6 12:29:52 vrajah.mydomain.tld dovecot: lmtp(14258, email@mydomain.tld): Error: fdatasync(/apps/mail/mailbox/attachments/23/12/2312039008db057a1c75-2efc2d00687d2952b2370000f89409f1) failed: Bad file descriptor

I'm using centos 6.4 on a KVM with ext4 as fs.

Can someone tell me why i'm getting this error? and how to fix this?

-Thanks in advance Vijay
