Long Mail Transit Time

Can anyone help to explain why the mail transit (enqueue to dequeue) takes so long to complete according to imslog.pl?

Is this a network issue or a MTA issue?

Hi,

Recommend you use a newer version of the imslog.pl script to see if you get different answers - there are a number of fixes/speed-ups in the latest version. I can email you a copy if you want (or it is included in the -63 messaging server patch if you have it installed under):

/opt/SUNWmsgsr/examples/unsupported/imslog.pl

Regards,

Shane.

Hi,

I have the latest comm5 installed as well. The script does not seem to be updated at all for 7 years. On the comment at the script header, the last update is Mar 3, 2000, which is the same as the one I have for comm4.

# 3-Mar-2000:jwa - Added support for debugging. If you set the environment

#variable PMDFLOGPLDEBUG to 1, the $debug varible will

#be set.

Any idea?

Thank you.

Hi,

The updated version wasn't included in 6.3 -- 6.3 introduces a number of new action & modifier codes which are unknown to the existing script. Also the new version has a very useful switch, namely LOG_QUEUE_TIME (refer to the 2006Q4 messaging server admin guide) which will make calculating the delivery times much much simpler (currently the script tries to match up enqueue-dequeue message id's etc.).

Haven't had a chance to update the script yet for 6.3 as I don't have any decent real-world data-sets to work with and I already have a lot on my plate :(

I could send you the latest version for 6.2 which will still be better.. just provide your email address.

Cheers,

Shane.

Hi,

I have run the updated script against my mail.log (comm4). I do not have production data for comm5 as I am still evaluating it.

There are about 305 lines of "Found an unsupported record type". Examples of such record are:

U TCP|172.16.3.65|25|125.225.102.102|4409 SMTP No such user 535 5.7.8 Bad username or password (Authentication failed).

U TCP|172.16.3.65|25|172.16.2.102|3653 SMTP Switched to channel tcp_auth user@domain 235 2.7.0 LOGIN authentication successful.

The following is the transit time from the latest script.

The times taken are still unreasonably high. What could be the problem?

Hi,

Do you want to send me a sanitised version of your mail log to the email address I sent you the imslog.pl script and I will take a look tomorrow. Chances are I either stuffed up some maths, or the wrong fields are being read in or something like that.

For the "U" line, this is "Logs SMTP authentication successes and failures. Format is the same as other O and C entries. In particular, the same

application and transport information fields appear in same order. The username will be logged in the username field if it is known. Bit 7 (value 128) of the LOG_CONNECTION MTA option controls this."

Most people don't enable this value so it hasn't come up yet --> easily fixed.

Cheers,

Shane.
