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?
