dovecot/FreeBSD and Android IMAP clients

25 Sep 2018


      Dear Colleagues,
I have a fairly vanilla setup of dovecot on FreeBSD, serving IMAP and POP3.
Thunderbird/IMAP works fine, and so does mutt/IMAP.
However, Android clients (Gmail/IMAP and K-9 Mail) have problems
accessing folders other than the INBOX. They either show them empty
with no mails (K-9) or just wait forever to view the contents (Gmail app).
Do I need to set up some workarounds or hacks in dovecot for Android
IMAP clients to work correctly? Any advice is appreciated.
My config is below:
2.3.2.1 (0719df592): /usr/local/etc/dovecot/dovecot.conf
OS: FreeBSD 11.2-RELEASE-p3 amd64
Hostname: admin.sibptus.ru
mail_location = mbox:~/Mail:INBOX=/var/mail/%u
mail_privileged_group = mail
namespace inbox {
inbox = yes
location =
mailbox Drafts {
special_use = \Drafts
}
mailbox Junk {
special_use = \Junk
}
mailbox Sent {
special_use = \Sent
}
mailbox "Sent Messages" {
special_use = \Sent
}
mailbox Trash {
special_use = \Trash
}
prefix =
}
passdb {
driver = pam
}
protocols = imap pop3
ssl_cert = </usr/local/etc/exim/mail.pem
ssl_dh =  # hidden, use -P to show it
ssl_key =  # hidden, use -P to show it
userdb {
driver = passwd
}
