Hello,

Personally I am still on Alma 9.7 which still has Berkeley DB (hash: 
support in Postifx).

However this is being deprecated and has been in EL10 and derivatives.

Quote:

Berkeley DB migration:

Some (Linux) distributions are removing support for BerkeleyDB databases 
(In Postfix, this means we lose support for the hash: and btree: lookup 
tables). See NON_BERKELEYDB_README for manual and partially automatic 
migration from btree: to lmdb:, and from hash: to lmdb: or cdb:.

The loss of BerkeleyDB affects Mailman versions that want to execute 
commands like "postmap hash:/path/to/file" when a mailing list is added 
or removed. Postfix provides a way to redirect such commands to a 
supported database type.

You don't have to wait until BerkeleyDB support is removed. It can make 
sense to migrate while BerkeleyDB support is still available (mainly, 
less downtime).

I know ghettoforge has a postfix3-lmdb package for support, which makes 
sense for me on alma 9 but why is it not the default in EL10 packages of 
ghettoforge?

I think the default package for postfix3 in EL10 Repo should already 
have lmdb and not require a separate package as it will be the standard 
anyway.

I assume the stock package of EL10 with 3.8.5 comes with lmdb support 
out of the box also.

Just an idea, thoughts?
