Greetings,

Per the subject line, how does pop3 get tcp-wrapped when using dovecot?

More specifically, when blocking email and (still) using sendmail, entries 
in /etc/hosts.deny look something like:
sendmail: xxx.xxx. etc (depending on the depth/degree)

for vsftpd it's
vsftpd: xxx.xxx (where the x's are parts of an octet)

for sshd it's
sshd: xxx.xxx

for pop3/dovecot it's?
????: xxx.xxx

I'm concerned about what is to the left of the colon (":"), not to the 
right.

Is it a dovecot.conf configuration also?

Much thanks,
