I added <sasl_mech_list: PLAIN LOGIN> to imapd.conf on the back-end server and the replication worked. So I wonder how I can tell sync_client which authentication mechanism to use? It seems like a feature request to me? or a hidden option to the sync_client executable. I'm playing with replication now and testing what happens if one deletes e-mails on the back-end server and not on the client. Will these mails be restored on the back-end by replication and when? -- Met vriendelijke groeten, With kind regards, Mit freundlichen Gruessen, De jrus wah, Wiel ************************************* W.K.
