[yerry]

hey everyone...I need some help

my domain server is mail.591ac.com
I can send a mail to every other domain

but I can't get mail at all

I got this

anyone can help me

BTW firewall is not the problem

Presumably mail.591ac.com is listening on port 25 yet zimbra is trying to deliver on port 7025.

[yerry]

but when I telnet mail.591ac.com 7025 and mail.591ac.com 25

I got

[root@cluster03 ~]# telnet mail.591ac.com 7025
Trying 127.0.0.1...
Connected to mail.591ac.com (127.0.0.1).
Escape character is '^]'.
220 mail.591ac.com Zimbra LMTP ready

[root@cluster03 ~]# telnet mail.591ac.com 25
Trying 127.0.0.1...
Connected to mail.591ac.com (127.0.0.1).
Escape character is '^]'.
220 mail.591ac.com ESMTP Postfix

and I telnet them from internet,I got the same respon

[Matt]

Try to telnet to 59.42.241.34 on port 7025 as that is what Zimbra is trying:

"connect to mail.591ac.com[59.42.241.34]"

[uxbod]

su - zimbra
zmcontrol -v
zmcontrol status

[yerry]

I got a problem when I try to telnet 59.42.241.34 7025 ..I can't get through ..

I think that is the problem

but my /etc/hosts is
127.0.0.1 mail.591ac.com

why lmtp access the 59.42.241.34 in port 7025

[uxbod]

Have you read the Zimbra Quick Installation Guide as /etc/hosts should look like

127.0.0.1           localhost.localdomain localhost
your.ip.address         FQDN yourhostname

[yerry]

I have set
172.16.120.203 mail.591ac.com

and I map 172.16.120.203 as 59.42.241.34 in firewall

so where is the problem??

[uxbod]

cat /etc/hosts
cat /etc/resolv.conf
dig 591ac.com mx
dig 591ac.com any
host `hostname` <- note backticks and not single quotes (type as is)

[yerry]

you mean I should add

59.42.241.34 mail.591ac.com

in server 's /etc/hosts?
