[Dovecot] Evolution IMAP with Dovecot as proxy

[Antonio Perez-Aranda]

I haven't a secondary dovecot server.

We have two passdb
  1. The first passdb check one attribute in LDAP (mailPlugins) if it
is empty, then the user match and Dovecot send the connection to
Courier
  1. The second passdb match at another case and Dovecot the same imap
instance server all data as normal.

Well, another possiblity is to use only some capabilities antil
migration is done.

I think that with this can be sufficient:

  imap_capability = IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE
NAMESPACE I18NLEVEL=1 SORT=DISPLAY THREAD=REFERENCES CHILDREN UIDPLUS
SEARCHRES CONTEXT=SEARCH QUOTA

And courier seem run.

Or is the proxy the same server as the destination Dovecot server? If so, I guess you'll have to run two Dovecot installations until the proxying is done .. or patch the sources so imap_capability is used only by imap-login, not imap.
