Title: The email server sends to email clients packets of 5 emails per session
Post by: girimia on April 01, 2019, 02:25:24 PM

Hello,

The email server sends to email clients (outlook) packets of 5 emails from the same sender address. But 30 emails were sent.
After a while, he will receive another 5 emails.
Where can I increase the number of emails that can be delivered to the email client in a single delivery?

Thank you,
Gabriel

I discovered the problem.
The ConcurrencyRemote and ConcurrencyLocal settings were set to very high values (1000 !?).
We have shrunk these values now, everything is all right.

Thank you!

Very odd.

They should both be set to 20

Code: [Select]

cat /var/qmail/control/concurrencyremote20

Code: [Select]

cat /var/qmail/control/concurrencylocal20

These are set in these templates and you can see the defaults are 20

/etc/e-smith/templates/var/qmail/control/concurrencylocal:1:
{ $DB->get('qmail')->prop('ConcurrencyLocal') || "20"; }

/etc/e-smith/templates/var/qmail/control/concurrencyremote:1:
{ $DB->get('qmail')->prop('ConcurrencyRemote') || "20"; }

You can probably reset them by just deleting the qmail keys, or setting them to the default values above.

You probably ought to go and look at the what qmail actually does, and IMAP. And find out why these settings were set so high.

The default 20 could be too low in lot of cases, you might need to increase it, but not that high ;)
