Howdy -
Hi Thomas,
I am running dovecot-2.2.24-1.fc23.x86_64 on Fedora 23. It's up to date
as of last night.
When I log in from a desktop using Thunderbird on Linux, my Android
phone (Nexus 6P) stops receiving mail. It happens if I'm on my laptop or
my desktop.
My wife has the same problem using Thunderbird on Windows. If she leaves
the house and forgets to shut down her MUA, her phone can't retrieve
messages.
Is this expected behavior? Can I change it? I feel like it's pretty
common for folks to have multiple devices which access the same mail
account. Between phones, tablets, PCs, etc., this seems like a pretty
common scenario.
no, that's not to be expected and should work pretty well.
It's a pretty vanilla setup:
[root@wintermute ~]# dovecot -n
# 2.2.24 (a82c823): /etc/dovecot/dovecot.conf
# OS: Linux 4.4.4-301.fc23.x86_64 x86_64 Fedora release 23 (Twenty Three)
mbox_write_locks = fcntl
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
}
ssl = required
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_cipher_list = PROFILE=SYSTEM
ssl_key = </etc/pki/dovecot/private/dovecot.pem
userdb {
driver = passwd
}
# 2.2.24 (a82c823): /etc/dovecot/dovecot.conf
# OS: Linux 4.5.5-300.fc24.x86_64 x86_64 Fedora release 24 (Twenty Four)
Used an F24 test VM which came up with the same Fedora default dovecot
configuration. I am a bit surprised that your's provides access to mail
though it has no configuration where the mailbox is located on the
drive: "mail_location" is empty as well "location" in the inbox namespace.
What is being logged in /var/log/maillog when the access fails? My test
system did log
Jun 20 20:37:36 fedora24 dovecot: imap-login: Login: user=<dalloz>,
method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=13441, secured,
session=<6G6V/7k1FNV/AAAB>
Jun 20 20:37:36 fedora24 dovecot: imap(dalloz): Error: User
initialization failed: Namespace '': Mail storage autodetection failed
with home=/home/dalloz
Jun 20 20:37:36 fedora24 dovecot: imap: Error: Invalid user settings.
Refer to server log for more information.
Made it working by adding
mail_location = mbox:~/mail:INBOX=/var/mail/%u
to /etc/dovecot/conf.d/10-mail.conf.
2 parallel IMAP logins then were no problem at all. The default limit on
your Fedora is
# doveconf | grep mail_max_userip_connections
Thanks!
Thomas
Kind regards
Alexander
