Hi,

I received a mail from amv.fr : 

Feb  7 15:59:54 mail1 postfix/qmgr[13756]: 48Ddkd6bGyz45TDH: from=<nepasrepondre2@amv.fr>, size=39209, nrcpt=1 (queue active)
Feb  7 15:59:54 mail1 postfix/smtpd[12433]: disconnect from mailhost01.filhet-allard.com[195.25.190.133] ehlo=1 mail=2 rcpt=2 data=2 quit=1 commands=8
Feb  7 15:59:54 mail1 postfix/pipe[12449]: 48Ddkd6bGyz45TDH: to=<me@mydomain.tld>, orig_to=<mealiased@mydomain.tld>, relay=dovecot, delay=0.
33, delays=0.24/0/0/0.08, dsn=2.0.0, status=sent (delivered via dovecot service)
Feb  7 15:59:54 mail1 postfix/qmgr[13756]: 48Ddkd6bGyz45TDH: removed

But I see nothing in my mailbox (roundcube), nor on my android phone (k9 mail via imap).

If I search 'nepasrepondre2@amv.fr' in /var/vmail, like : 

grep -r 'nepasrepondre2@amv\.fr' /var/vmail

I have no result at all.

I receive emails from other hosts. Don't know what's going on at all.

Edit:
in dovecot logs, I have :

Feb  8 15:51:01 mail1 dovecot: auth: Error: passwd-file: open(/etc/dovecot/dovecot-master-users) failed: Permission denied (euid=108(dovecot) egid=114(dovecot) missing +r perm: /etc/dovecot/dovecot-master-users, dir owned by 0:0 mode=0755)

Ran : 

ls -l /etc/dovecot/dovecot-master-users
-r-x------ 1 root root 134 Jan 13 23:08 /etc/dovecot/dovecot-master-users
chmod 544 /etc/dovecot/dovecot-master-users
ls -l /etc/dovecot/dovecot-master-users
-r-xr--r-- 1 root root 134 Jan 13 23:08 /etc/dovecot/dovecot-master-users

Any clue ?
Regards

Re: Missing mail from particular host

Run “chown dovecot:dovecot /etc/dovecot/dovecot-master-users“ to fix it.

OK, thanks, I don't think that's the root cause, because i receive other mails

Re: Missing mail from particular host

Then please extract related error log from Postfix log file, cannot help much without log.

Re: Missing mail from particular host

The logs are there since my first post, there's no error, that's my main issue :

Feb  7 15:59:54 mail1 postfix/qmgr[13756]: 48Ddkd6bGyz45TDH: from=<nepasrepondre2@amv.fr>, size=39209, nrcpt=1 (queue active)

Feb  7 15:59:54 mail1 postfix/qmgr[13756]: 48Ddkd6bGyz45TDH: removed

Please, read my first post, searched mail in /var/vmail with no result

Re: Missing mail from particular host

- Does user "me@mydomain.tld" have any mail forwarding? Or redirecting (in sieve rule)?
- Any error in /var/log/dovecot/*?

Re: Missing mail from particular host

Strange, no more errors since this.

Catch all enabled, and an alias exists to move *@mydomain.tld => me@mydomain.tld

Any clue for missing mails ?

Re: Missing mail from particular host

You said "Strange, no more errors since this."

So this seems fixed?

The log you posted has a completly different timestamp, if it is just one mail missing, you should post the related log

Re: Missing mail from particular host

Cthulhu: already done here

There's no error in /var/log/mail.log that's my problem (like you can see in the linked post).

Dunno how an email can disappear like this.

Re: Missing mail from particular host

Can you find it in the particular mail folder?

Re: Missing mail from particular host

Cthulhu: already searched with grep, read the first post. In GUI, nothing (for sure).
