Hello,
I want to ask if somebody have this problem and solved it. I have cPanel server which works great, but if server is sometimes restarted during maintenance, emails are not delivered due to 550 Invalid HELO string.
When I checked Change hostname, there's only first name of server from fqdn (so for example only server from server.domain.com).
I already ask about provider about this, and they tell me that server has valid fqdn already set, and they are true, when I put hostname -f I get full server.domain.com. Just hostname return only "server". Which is valid behaviour.
Is it any switch or something to force cpanel to use fqdn name not only first server name?
P.S.: When I changed name in cpanel, it set name of server to fqdn, so everything works, but it shouldn't work like this.
Thanks.
