Hi,

i've seen a strange behaviour in our system (centos 7, dovecot 2.2.36
(1f10bfa63) today.

We got a mail and it got delivered.

Dec 3 07:56:25 mail postfix/lmtp[4013]: 915B0CEF4C2: to=<user@domain>,
relay=mail[private/dovecot-lmtp], delay=1.5, delays=1.3/0.03/0.02/0.19,
dsn=2.0.0, status=sent (250 2.0.0 <user@domain> AOhCNBgH5l2vDwAAtnFApQ:2
Saved)
Dec 3 07:56:25 mail dovecot: lmtp(user@domain):
AOhCNBgH5l2vDwAAtnFApQ:2: sieve:
msgid=<289913405.81.1575356173625.JavaMail.SYSTEM@EUWS0716>: stored mail
into mailbox 'INBOX'

I also see this mail on the filesystem in the users cur dir:

-rw-r--r--. 1 vmail vmail 448818 3. Dez 07:56
1575356184.M937345P4015.mail,S=611100,W=619338:2,Sae

But i don't see this single mail in thunderbird and not in sogo
(http://www.sogo.nu), but i can see it in the mobile mail client.

Does anyone have a suggfestion what may be wrong here?

I paste my dovecot -n output here:

Hi,

i'd like to be a bit more specific on the mobile client, the mobile
client which is working is the samsung integrated "Mail" client.
https://play.google.com/store/apps/details?id=com.samsung.android.email.provider&hl=en

With K9-Mail it doesn't work either.
