[vchkpw] Migrating Domains to new Vpopmail Server
Hi all, I have my new vpopmail server complete (yippee!). This one does chkusr and tarpitting - (the old server was somewhat vulnerable to dictionary ttacks and had lots of messages in the queue usually. Thanks to all for great software and enhancements. My question is this: There is now qmail locals file. As I change MX records, I would like the old server to forward mail to the new one. How can I change the vpopmail locals database and not change the rcpthosts? I guess I could vdeldomain and add back the domain to rcpthosts, is that the best way? -- David Bronson
RE: [vchkpw] Migrating Domains to new Vpopmail Server
/var/qmail/control/smtproutes Format is similar to the /var/qmail/control/virtualhosts file. foo.bar:new.server.dom Where foo.bar is the domain name and new.server.dom is the mail server to route mail for that domain to. new.server.dom can be a domain name, or an IP address. Note that foo.bar and new.server.dom are separated by a colon. -Original Message- From: David Bronson [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 17, 2003 7:00 AM To: [EMAIL PROTECTED] Subject: [vchkpw] Migrating Domains to new Vpopmail Server Hi all, I have my new vpopmail server complete (yippee!).

I did this recently on a server using CDB, and here are the general steps that I did, in order. stop qmail on old add domain.com to new (use any password, next step will fix it) copy ~vpopmail/domains/domain.com from old to new (I used rsync, ssh would work as well) change MX record on DNS server to point to new remove domain.com from old add domain.com back to rcpthosts on old make sure old has new MX record for domain.com start qmail on old Keep in mind that this worked for me because server old was also the DNS server for all of the domains, so I was sure it would have the correct MX record for each domain as I moved it. If you don't have that luxury, I think you can use smtproutes on the old server to force it to relay the mail to the new server. I was able to automate a lot of the process using scripts and ssh between the two hosts (I set them up as trusted hosts so I wouldn't have to constantly enter my password). Don't forget to move the alias domains as well! They don't appear in ~vpopmail/domains -- you'll have to look in /var/qmail/users/assign to find them. -- Tom Collins [EMAIL PROTECTED]
