This Roundcube plugin allows you to setup identities with different SMTP servers from the RC installation's default.

This plugin is available from Packagist.

$ cd /path/to/roundcube/plugins
$ git clone https://github.com/deflomu/Roundcube-SMTP-per-Identity-Plugin.git identity_smtp

To use a specific version:

$ git checkout 1.6.0

Replace 1.6.0 with any version found here

The plugins folder must be named identity_smtp.

Add identity_smtp to $rcmail_config['plugins'] in config/main.inc.php.

A default SMTP server has to be set in config/main.inc.php, otherwise Roundcube will not call any SMTP function and the plugin will not work.

Each version's Major + Minor will match the latest version of Roundcube that it's compatible with. If you cannot find a version for your install, use the closest-matching newer version.

In the Identities settings you can specify an alternative SMTP server for every identity to send mail with. When composing an email, just choose the identity you want to use to send mail.
