SOLVED: Re: MailScanner is processing queue every 300 seconds.

[Armando Montiel]

Hi,

Thank you Martin.

You have pointed me to the right direction, but I would like to share why I
never think in this value before:

My "Delivery Method" was in "queue", so I was mind blocked about not change
this parameter. I was convinced that this value have no relationship with
my "batch" behavior.
Another value hat was necessary to change was not in MailScanner but
master.cf in Postfix:

cleanup, flush, pickup and qmgr values was setup to "unix", but the new
delivery method was unable to handle. I need to change qmgr value to "fifo"
in order to get this working.

Now I have delays with less than 20 seconds, which is pretty good, but I
dont know already if this will handle my users the next monday.

I will investigate which "fifo|unix" values have better performance under
Postfix and a heavy imap usage under Cyrus-imapd.

Thank you again.

Batch is the clue word there specifically the setting is
http://www.mailscanner.info/MailScanner.conf.index.html#Delivery%20Method
This is how is should work in batches but a 5 min interval isnt right
I'd check the setting to call the second mta (sendmail2) setting is correct

Hi,
I am using a mail server solution where MailScanner is used with postfix
+ cyrus-imapd.
Any clue about why this combination of software spends 300 seconds (5
minutes) to process and deliver email?
This is like my server take a look in the queue and process this in a
batch way, not individually.
The best time I get in this scenario is when a email is received in the
queue 15 or 20 seconds before the last processing cycle of 5 minutes has
been performed.
Sometime in the past this didn't happened but I am lost looking for a
possible reason.
Which MailScanner variables could make this effect?
Thank you.

Might be best to have the scanner part running on a separate machine to the
mail server. Reduces issues with performance queries but also means
internal email (between your own users) doesnt get scanned which keeps
performance up

Also means if the mailscanner bit fails uou can still transit internal email
