[Dovecot] 1.1rc10: istream-crlf.c: assertion failed: (size != 0)

[Marco De Benedetto]

Hi,

I am migrating from 0.99.14 to 1.1.rc10 and from mbox to maildir.

During the conversion, via convert plugin, I get this assertion failure:

2008-06-13 14:12:54 Fatal: IMAP(username): Mailbox conversion failed, exiting

If it can be useful for debugging purpose, is there something I can do to
identify the mailbox causing the failure?

I am also investigating why the plugin tried to recreate directory for the
already converted mailbox Ospedale.

[Dovecot] Thunderbird and imap alerts

[Marco De Benedetto]

Is Thunderbird supposed to show alerts sent via post-login scripts as in the
wiki example?

dovecot-imapd 1.0.5-1 (Debian)
Thunderbird (Icedove) 2.0.0.4 (Debian)

# dovecot -n|grep 'mail_executable(imap)'
mail_executable(imap): /usr/local/sbin/dovecot-alert.sh

# cat /usr/local/sbin/dovecot-alert.sh
#!/bin/sh

echo * OK [ALERT] Hello World.
exec /usr/lib/dovecot/imap

Logging in with Thunderbird I get this alert: Mail server imap.example.org is
not an IMAP4 server.
