Mail forwarding to a dynamic IP address.
I have a Cyrus installation with postfix and open xchange. I get the mails from catchall account with procmail and distribute with the mail server. Now I have a new site office where couples of staff members are going to be relocated. Since we have only an ADSL line on site office if there any way I could forward the mails for these staff members to another Mail Server with dynamic IP address? Any input will be really appreciated.

Use a dyndns service [1] to make the remote ADSL IP resolvable by name and forward directly to that, then forward port 25 in Your firewall setup at the remote site to the mailserver inside the remote intranet (guessing at Your setup here). e.g. have Your distributing mail server's virtual-maps state something like this [EMAIL PROTECTED] [EMAIL PROTECTED] NB: After automatic disconnects of the ADSL line until Your dyndns-client updates the IP You will get timeouts in Your logs but those are temporary and should be retried anyway. To make things look nice You can create an explicit MX record for the dyndns domain. Remember to set the remote mailserver to accept mails addressed to the dyndns domain. Even nicer: Use TLS between the two servers, maybe even with certs.

Hi, Quoting Rajeev R Veedu [EMAIL PROTECTED]: I have a Cyrus installation with postfix and open xchange. I get the mails from catchall account with procmail and distribute with the mail server. Now I have a new site office where couples of staff members are going to be relocated. Since we have only an ADSL line on site office if there any way I could forward the mails for these staff members to another Mail Server with dynamic IP address? You can set up an DDNS Server (Dynamic Domain Name Service) or use a free DDNS and tell the DDNS the new IP every time you connect via DSL. Or you use fetchmail or imapsync to download the E-Mails from the Main Mailserver Any input will be really appreciated. Thanks Rajeev R. Veedu.
