Thanks. I found out how to call dovecot as a lda from fetchmail, but
could not see how to do it from offlineimap. So I'm now using the
following architecture, which works well in practice but is a little bit
complex.

#+begin_example
  +------------+     +-----------+      imap sync       +----------+      +----------------+
  |mail clients|-----|remote imap|----------------------|local imap|------|  mail clients  |
  |(webmail,   |     +-----------+    (offlineimap)     |(dovecot) |      |(gnus, Mail.app)|
  | smartphone)|           |                            +----------+      +----------------+
  +------------+           V                               ^  |
                           |   fetch mail and filter it    |  |
                           \______________________________/   |
                              (fetchmail + dovecot lda)       |
                                                              |
                                                        +------------+     +---------------+
                                                        |mail storage|-----| mail indexing |
                                                        | (maildir)  |     |   (notmuch)   |
                                                        +------------+     +---------------+
