dovecot - Feb 2011 - systemd socket and service

Hello. I'm use systemd and have some questions:

1) Why dovecot.socket contains only imap ListenStream?
[Unit]
Description=Dovecot IMAP/POP3 email server activation socket

[Socket]
#dovecot expects separate IPv4 and IPv6 sockets
BindIPv6Only=ipv6-only
ListenStream=0.0.0.0:143
ListenStream=[::]:143
ListenStream=0.0.0.0:993
ListenStream=[::]:993
KeepAlive=true

2) Does dovecot.service required to use dovecot lmtp, or it may be
stoppped (i not often check my mails via client, but have many incoming
mails some time)

You mean why doesn't it contain POP3? I guess mainly because that's how
it was submitted to me and I didn't think of it. Also now that I do think
about it, I'm still not sure if it should contain POP3 by default. Even
Dovecot's on example-config doesn't enable POP3 by default.

I don't understand. If you want LMTP enabled, you also need to list its
socket to dovecot.socket. LMTP is executed in a similar way to IMAP/POP3. (If
you want LMTP via UNIX socket, I don't really know the answer to that. Does
systemd support listening on UNIX sockets? Maybe it requires patching Dovecot
more.)
