Hi,

what are the following messages supposed to tell me and does this
indicate a problem?


# systemctl status cyrus-imapd
[...]
master[3766]: unable to setsocketopt(IP_TOS): Operation not supported
master[3766]: unable to setsocketopt(IP_TOS): Operation not supported
[...]


Exim says it can not connect to the lmtp socket even when selinux
doesn?t get in the way.  The configuration looks like this:


cyrus.conf (none of the two options work):

[...]
   # lmtp                cmd="lmtpd -a"
listen="lmtp:127.0.0.1" prefork=4
   lmtpunix      cmd="lmtpd -a"
listen="/var/lib/imap/socket/lmtp" prefork=4
[...]


exim.conf:

[...]
begin transports



# cyrus_ltcp:
#   driver = smtp
#   protocol = lmtp
#   delivery_date_add
#   envelope_to_add
#   return_path_add
#   hosts = localhost
#   allow_localhost

lmtp_socket:
   driver = lmtp
   socket = /var/lib/imap/socket/lmtp
   delivery_date_add
   envelope_to_add
   return_path_add


# ls -la /var/lib/imap/socket/lmtp
srwxrwxrwx. 1 root root 0 Mar 16 12:58 /var/lib/imap/socket/lmtp


I have this working on the old server (which doesn?t run Centos) and am
trying to migrate it to the new one (which runs Centos 7.4).  The
version of cyrus and sasl are the same on both machines.

What?s the problem with Centos that these things don?t just work as they
usually do?
