smtp problems
  Posted by  Peter Mitterboeck  on Wednesday, February 18, 2004 at 11:26:35 AM (EST)
Since upgrading from lansuite 2002 to 2003, I have an interesting problem: when sending email from any workstation, it takes over 2 minutes before the transfer of data between workstation and lansuite server starts:
16:02:31 SMTP: [2] 'acer-schlepptop' [] connected.
16:02:31 SMTP: [2] SMTP connection to 'acer-schlepptop' established.
16:05:22 SMTP: [2] Receiving message to 'D:\LANSUITE\io\internet\2eff5bec.d'.
16:05:22 SMTP: [2] Message received (2062 B).
16:05:24 SMTP: [2] SMTP connection to 'acer-schlepptop' properly terminated.
So the network works fine, ther are no other problems or errors, just this delay when processing a message.
Now I tried to send a message via telnet:
250 Welcome acer-schlepptop
mail from:
250 Sender Ok
rcpt to:
250 Recipient Ok
354 Please start mail input.

250 Mail queued for delivery.
The point is that the smtp-server hangs for 1-2 minutes at the "rcpt: to" - command before it accepts the recipient. Is this a bug or can I do anything to make the server act faster? This problem never occurred in lansuite2002!
By the way, this has nothing to do with antivirus software!!!

... another fact is that via webmail you don't expect timeouts! testmail vie webmail interface left the workstation and the server within seconds!!!

it's me once again. Could it be possible that the time issue correlates with the anti spam lists selected?
I thought the anti spam lists are used when retrieving email from the internet, not when sending email to the internet!?

See my notes on my problem thread that you had responded earlier.

Could this have anything to do with anti-spam? Maybe. What happens when you turn off the anti-spam stuff?

I could see where it could take a while to contact your DNSBL lists and/or process it against your anti-spam settings..especially the DNSBL's as they are hosted elsewhere.

Likewise, if you have a large number of servers/addresses in your block list, it's possible it could take a while to process this.

I mentoned in the other thread that the server is a queuing server. I'm quite experienced with these types of servers, as they are commonly used in the *nix environment (Sendmail, for example is commonly used as a SMTP+Queuing server, in fact, I believe RedHat Linux uses Sendmail in the capacity as default, for example.

A Queuing server stores the message and then processes it when resources are available, on a connection schedule, etc. I have noticed in LS, this schedule is about 1-2 minutes or so and appears to be hard coded into the program (Ie, I don't see any way to change it)...

It is the SPAM filter list. What is the minimum selection? Which one is the best on the list?

I deselected my previous choices and now everything runs fast.

Isn't there a way to check SPAM only on incoming email?

The case is closed for me.
