Re: DB files across machines
* Gaby Vanhegan g...@vanhegan.net: Is there a portable way to share postmapped file across machines? Yes: 1) share the text files, then use a Makefile to convert them on the target systems 2) Use compatible BerkeleyDB versions 3) Don't use BerkeleyDB, use CDB -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de

Is there going to be some architectural difference between the two systems? Is there a more cross-platform file format I could use for the databases? The BerkeleyDB used for hash and btree are known for their always changing file format so don't copy db files from one machine to the other. Either use a network database like LDAP,MySQL,PostgreSQL or stick with plain text and build them on the machine in question. You *may* get around with using cdb but don't take it for granted. I was under the impression that there was a performance penalty using CDB with Postfix? -- Expounding the theory of infinite Abelian Badgers http://playr.co.uk/

I have one postfix server running OpenBSD and another running CentOS, I want the CentOS server to provide secondary services for for the BSD box. The OpenBSD box uses virtual delivery: /etc/postfix/main.cf:(BSD box) ... # What are the domains that we handle mail for? virtual_alias_domains = hash:/etc/postfix/virtual_domains virtual_alias_maps = hash:/etc/postfix/virtual The two plain text versions of those files are copied over to the CentOS server and renamed so they act as a relay reference: /etc/postfix.main.cf (CentOS box) ... # Relay for ourselves and other hosts relay_domains = $mydestination, hash:/etc/postfix/relay_domains relay_recipient_maps = hash:/etc/postfix/relay_recipients My setup currently copies the plain text versions and creates a flag file. A cron job then looks for the flag file and postmaps the files if needed. Use incron instead of cron.
