Hi,
I have found this strange problem. I'm working with Debian 6, dovecot
2.1.9 and vpopmail-auth.
LDA is configured and works fine but the problem is when the first
message arrive "dovecot-lda" return a "Segmentation fault", the message
is written to the user's Mailbox but the message remains, also, in the
queue of qmail (deferral: Segmentation_fault/) and at the second attempt
is delivered fine.
If disable ACL (acl and imap_acl from mail_plugins) in dovecot.conf
"Segmentation fault" go away. Moreover, without ACL at the first
delivery folders like Sent, Drafts, Trash, Spam appear immediately.
An example,
new user:
root@demo-vpop ~ # tree
/home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ -a
/home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/
