Hi guys, im very new to this linux and email server thing. our exchange license almost expires and im seeking new alternatives, zimbra looks promising but i have never ever setup a email server and some concepts are very new to me, im doing some tests firsts before doing any decision,i have managed my self to setup the zimbra server i can recieve any mails but cant send mails, and the pop3 and imap thing dont work, let me explain my case:
1) we dont own a domain yet, so i registered one at dyndns "test.gotdns.com" is my domain for tests.
2)i downloaded the virtual appliance for some testing.
mail relay "test.gotdns.com"
mail from "firstname.lastname@example.org"
my first confusion i have read the help article but i just dont get it
Host Name test.gotdns.com
DNS Search Domain localdomain <----is that correct?
DNS Server(s) 192.168.152.254 <---- thats my router IP or what dns server should i put here?
IP Address 192.168.152.253
Gateway 192.168.152.254 <---my ip router gateway
Blank, i have no idea what it is
some text scrolled and "done" u now can log in to the admin site
2)i went to my router and redirected all the ports to 192.168.152.253
3) i went do the admin site and i can see 1 domain, 1 server
virtual host <--
General---> LMTP advertised Name , LMTP bind address <-- blank ATM
Services--->all marked, imap pop proxy & SNMP unchecked
MTA----->Relay MTA for external delivey, and MTA trusted domains "Blank"
POP-----> address, adverticed name in blank
Zimbra seems to work fine, i can access to the ZCS via web from my house, my GF's House, with my admin account, and i can recieve mails. but i dunno why cannot sent any mail, they are in the queue line with the following error "Connect to mx1.hotmail"(hotmail.com) or "Connect to as.lajat.com.mx"(lajat.com.mx), this is what i did, and im stuck, any suggestions? thanks for any help in advance.
