SMTP Mail Domino

HELP!! For some reason, our outbound mail queues up. If I check the log some mail eventually gets sent but it’s slow. I really need help with this. It sounds like a network issue somehow but that’s out of my realm.

Heres a portion of what I see in notes.log:

1/19/2003 01:31:31 PM [0774:003A-136C] SMTPClient: Data Send Failed 73692 bytes, Status: 2562

11/19/2003 01:31:31 PM [0774:003A-136C] SMTPClient: Connection broken after an error sending DATA command

11/19/2003 01:31:31 PM [0774:003A-136C] SMTPClient: Attempting to SubmitMessage:

11/19/2003 01:31:31 PM [0774:003A-136C] SMTPClient: Attempting to Disconnect:

11/19/2003 01:31:31 PM [0774:003A-136C] SMTPClient: Connection already disconnected

11/19/2003 01:31:31 PM Router: No messages transferred to 206.64.128.147 (host 206.64.128.147) via SMTP

I also see where the host is no longer responding. This mal server is in the DMZ. We do have a firewall in place.

Thank You!

Mich,

A few questions:

Was there anything in the log about http://pobox.com or similar?

What kind of firewall are you using? Some people have had this issue with Watchguard Firebox’s

Can you tell who the message is going to, and thus have a look at it in your mail.box?

How many mail.box do you have?

Cheers

Ben

Thanks Ben for your response…

No, no reference to pobox.com.

We have one mail box.

These are multile messages, different recipients, different senders. It’s all outbound email.

Thank You!

Are you going via a relay, or direct to other SMTP servers?

Could be something to do with MIME - next time it happens, see if there are any mails with .htm attachments, and delete them (or just cut them from the db) and then see if the router starts going again.

cheers

Same results. I have emails still queued.

[0774:0040-0414] SMTPClient: Connection broken after a network read timeout

This I just saw in the notes log. Also, when I first start a console session I see this:

DNS: non-existent Domain

SORRY again… I never answered your relay question. I am so busy, I must have 30 different tasks running on my machine right now…

Anyway, I see an address in the COnfiguration document for relay to. I am very new to this Domino stuff, I didn’t set the server up. I did do the upgrade from 4.67 to 6. The messages like above lead me to think it’s a network issue. Or, maybe the server is simply slowing down and I need to start monitoring it’s performance a little more closely.

Thank You.

Hi Mitch,Green or grey at Notes I think you’ve hit the spot. This is a network issue. And I can tell you it’s a DNS issue. The DNS server your outbound SMTP Domino server is querying has problems keeping up the speed. This means that Domino has to wait for the DNS answer sooooo looooong that the session finally times out. This is also the case why you see mails are being delivered but at a VERY slow pace.

It is very important that the nearby network resources are up to spec. and can keep up the pace with the Domino server.

…however this leads me to another thought. There is also the possibility that one of the boxes nearby the fierwall might be suffering from computer virus. You have some network viruses that flood the network with “ping” signals etc. and they can cause the network to slow down a lot and even stop.

Hope these ideas can lead you further in your quest

Good hunting

Thank You SO MUCH. When this first started, or atleast when we first noticed it, I said DNS. But I’m not a network person and I got beat for it. I will certainly give this to our network person because unfortunately I don’t have the expertise in this area. Thank You again!

How about a memory leak? Would a memory leak cause something like this? Or Symantec virus scanning software? That was one of my initial thoughts so I checked the settings there. There isn’t anything that says specifically “scan outgoing”. I did change the heuristic settings to MED instead of HIGH. The incoming mail moves fast, within seconds even though it’s scanned on entry.

Thank You

Sorry…

We use a Nokia Firewall. IPSO OS (?)

This goes back to 11.13 and probably earlier. It appears that the email finally goes but is slow.

Thank You
