Hi guys,

I'm trying to work out how to configure XMail to accept all mail for a domain, then attempt to forward that mail on to a specfic mail server. Basically, I just want to provide a backup mail server for one of my clients - if their mail server is down, the mail will come to my server, and I need it to attempt to forward it on to their mail server.

What I *don't* want is for XMail to do a DNS lookup for the MX records for the domain, and try and deliver the mail that way, as if it cannot connect to the primary mail server, it'll attempt to deliver the mail to itself again.... = messy smile.gif

So to recap:

client.com's MX records:

mx1.client.com (clients' primary mail server)
mx1.mydomain.com (my XMail server)

If a MTA out on the net can't connect to mx1.client.com, the mail will be sent to mx1.mydomain.com. XMail running on mx1.mydomain.com needs to accept *any* mail addressed to *@client.com, and attempt to forward the mail on to mx1.client.com.

Any ideas guys? smile.gif I'm asking for help as I don't want to accidentally turn my mail server into an open relay.

Cheers,
John smile.gif

Use custom domain processing.
Under custdomains directory create a mx1.client.com.tab file with following lines in it:
"smtprelay"[TAB]"server"[NEWLINE]

Note: TAB is real tab character and NEWLINE is real return.

To prevent your server being an open relay uncomment in server.tab line:
"EnableAuthSMTP-POP3" "0"

Clear smtprelay.tab file, in smtp.ipmap.tab you need to have:
"0.0.0.0/0"[tab]"0.0.0.0/0"[tab]"ALLOW"[tab]"1"[newline]
