Re: Headsup on feature removal

Hi!

I understand that it is not trivial to move away from vpopmail and does require changing a working system. But then again, one should be able to configure MySQL passdb/userdb with vpopmail schema.

I am not familiar with vpopmail but if someone comes with instructions we can polish them a bit (if necessary) and publish them as howto on doc.dovecot.org.

So I am on of the many users with qmail, and using vpopmail auth, I guess chatting with some other guys in the other mailing list we will convert to mysql driver but this is a lot of work for many people. 

I do understand dropping things out but a valid solutions needs to be proposed.

Those plugins can be resurrected with simple git revert. Are you planning on open sourcing your client id authetication plugin? Aki

With these planned changes, you mention they will be removed from 'core', so is the intention to allow more of these legacy plugins to more to their own repo's for those that might still want to use them?

Eg, more in the the path of plug-in architecture? Just curious for clarity.

Oh, and have to add.. still waiting on the variable capability patch, to allow plugins to modify advertised capabilities. (#pull request 86)

This will allow us to provide our dove cot plugins more widely to the community.

Hi!

Dovecot is now a nearly 20 year old product, and during that time it has accumulated many different features and plugins in its core repository.

We are starting to gradually remove some of these parts, which are unused, untested or deprecated. We will provide advance notification before removing anything.

To start, the following features are likely to be removed in next few releases of Dovecot.

• Authentication drivers: vpopmail, checkpassword, bsdauth, shadow, sia
• Password schemes: HMAC-MD5, RPA, SKEY, PLAIN-MD4, LANMAN, NTLM, SMD5
• Authentication mechanisms: ntlm, rpa, skey
• Dict drivers: memcached, memcached-ascii (use redis instead)
• postfix postmap support
• autocreate & autosubscribe plugins (use built-in auto=create/subscribe setting instead)
• expire plugin (use built-in autoexpunge setting)
• fts-squat plugin
• mailbox alias plugin
• mail-filter plugin
• snarf plugin
• xz compression algorithm

For the authentication drivers that are being removed, we suggest using Lua as a replacement. See https://doc.dovecot.org/configuration_manual/authentication/lua_based_authen...

For information about converting between password schemes, see https://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes

If you are using any of these features, please start preparing for their removal in the near future. Features will begin to be dropped as of v2.3.11.

Additionally, the mbox format will no longer receive new development. It will still be maintained, however its use beyond migrations and other limited use cases will be discouraged.

Please contact us via the mailing list if you have any questions.

Regards, Dovecot Team
