[SOLVED] quotacheck & mail incompatibility

Hello,

Here is a mystery.
My script is the following:

#!/bin/bash
set -xv
quota_report=$(mktemp)
{ quotaoff -va && quotacheck -vafmn; quotaon -va; } &>$quota_report
mail -s "[QUOTA] [$(uname -n)] Mise à jour des quotas" "root@localhost" <"$quota_report"
echo "rc=$?"

Output seems ok, temporary file is created and its content is OK but NO email is sent (I have nothing in inbox, spam or any folder).

If I just modify:

{ quotaoff -va && quotacheck -vafmn; quotaon -va; } &>$quota_report

into:

{ quotaoff -va; quotaon -va; } &>$quota_report

Mail is sent as expected initially.
quotacheck seems to be problematic for mail...

Can somebody explain me this behavior please?
Thanks in advance

PS: how can I inspect mail logs with journalctl please? I'm using exim4

One question:
what is the purpose of running quotacheck?
It is high stress for the disk.

Ok, I've spotted the error thanks to switch -v added to command mail:

T=remote_smtp: message is too big (transport limit = 1)

Indeed, quotacheck is somewhat interactive as its output displays a kind of ASCII spinning wheel while user is waiting for it to check quotas. Thus each step of this spinning wheel is decomposed of non printable |/-\ characters (like sprites) in my $quota_report redirected output file and I end up with too long lines inside the file (when waiting time has been very long) to be sent by mail.

I know there is flag IGNORE_SMTP_LINE_LENGTH_LIMIT you can set to 1 in exim4 config files but I've simply switched to mutt instead of mail command in my script.
Problem resolved

I want to verify there is no discrepancies with my samba shared quotas. Is it bad practice?
