Well ... it doesn't seem so. Just to make sure I am doing it the proper
way, I will list what I did to get the result : 

1. Follow your link and copy the content of the patch in a local file
named dovecot-diff-02.patch

2. Apply the commande $ patch src/login-common/main.c
dovecot-diff-02.patch

3. $ make
4. # make uninstall
5. # make install
6. # strace -o strace-dovecot dovecot

From this, I do have the strace result of the imap-login executable
which is attached to the email. 

For this test, I will restate the dovecot -n command as its output is
different since I use the compiled version : 

# dovecot -n
# 1.1.13: /usr/local/etc/dovecot.conf
Warning: There is no way to login to this server:
disable_plaintext_auth=yes, ssl-disable=yes, no non-plaintext auth
mechanisms.
# OS: Linux 2.6.27.19-server-1mnb i686 Mandriva Linux release 2009.0
(Official) for i586 
ssl_disable: yes
login_dir: /usr/local/var/run/dovecot/login
login_executable: /usr/bin/strace
-o /root/strace-imap-login /usr/local/libexec/dovecot/imap-login
auth default:
  passdb:
    driver: pam
  userdb:
    driver: passwd

(Well it says there is no way to login but at that stage it's not
important as imap-login can't even start. I will bother with
reactivating SSL later on)

Also, as you might have noticed, I also added strace output for the
dovecot executable itself in case it can be of any use. 

Let me know if you need it or any other kind of tests to be done.

Hope this helps
Thanks !
