So I installed dovecot and tried to connect via telnet to port 143. Dovecot is configured to listen:

> doveconf listen protocols
listen = *
protocols =  imap

is running:

> ps auxf | grep dovecot
root     19123  0.0  0.4   2984  1784 ?        Ds   16:14   0:00 /usr/sbin/dovecot -c /etc/dovecot/dovecot.conf

and is listening:

> netstat -ptan | grep ':143'
tcp        0      0 0.0.0.0:143             0.0.0.0:*               LISTEN      19123/dovecot

But after connecting to it, it doesn't greet nor react to a login try:

> telnet 127.0.0.1 imap
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
A1 LOGIN user pass

Nothing happens!

I activated all debuggin options:

> egrep -v '^\s*(#|$)' /etc/dovecot/conf.d/10-logging.conf           
auth_debug_passwords = yes
mail_debug = yes
plugin {
}
> doveconf auth_debug_passwords mail_debug
auth_debug_passwords = yes
mail_debug = yes

but I don't see anything beside the startup message in the syslog

> tail -f /var/log/syslog | grep dovecot
Feb  1 16:14:28 hostname dovecot: master: Dovecot v2.1.7 starting up (core dumps disabled)

It seems, that this is the same problem as Dovecot hangs on all logins including local telnet. I have an open nfs mount with a currently offline server. After disabeling the mount dovecot startet flawlessly. Also http://wiki2.dovecot.org/Mountpoints might help.
