PostPosted: Fri Mar 04, 2005 12:43 am    Post subject: IMAP connections delayed Reply with quote Back to top

I've noticed that connections to the IMAP server I use become flakey when I'm using my LinkSys RT31P2 router. This happens whether I'm connected directly to the router or via my wireless router, which is in turn connected to the LinkSys. Removing the router (as I have tonight) eliminates the problem.

So here it is:

After a short time using email (this doesn't seem to happen right after cranking it up), communication with the IMAP server becomes very slow, sometimes taking minutes for a simple reply to a NOOP. The SMTP connection does just fine at the same time. (I can see this in the client's logs, but also my message gets sent ASAP, while the copy to sent-mail folder hangs.)

I use SSL connections to both servers. I've tried changing the MTU to 1492, 1462 and 1400, then I gave up.

OS X 10.3.8, Mulberry and Mail.app clients, wired or wireless (via Airport Express, so I can't switch the order they're in).

So, any thoughts?

I've been having the same exact problem, but never thought it would be related to the LinkSys/Cisco device. But now that you mention it, the problem has been occurring for about the same time that my device has been active, both before the POTS number transferred and after, for about 6 weeks now.

My configuration is a D-Link DI-614+ router, mostly wired. My home email server is a Windows 2000 system running Kerio Mailserver and connected via CAT5. Kerio pulls POP3 mail into a local mail store that we access via an IMAP client (Mozilla Thunderbird) on Windows XP machines connected via wire or WiFi. Internal IMAP access within our LAN does not require SSL (can use port 143), but only the SSL port (993) is open through the router for external IMAP access.

The symptoms are exactly like you say, and very intermittent (a failure of this sort is the exception, not the rule). After composing a message and sending, the appearance is that the message does not get sent. There is no copy placed in the Sent Items folder. However, having had this happen once on a message sent to my wife, I know that all 4 attempts sent messages. It's just the copy didn't get into Sent Items.

I have not seen this problem when accessing the server remotely via IMAP, but then I rarely do (only when on travel). However, I am pretty sure I have seen it both on machines configured to use SSL and not. Accessing web mail from work (Kerio has a webmail interface too) works fine.

I haven't messed with my router performance settings.

Have you tried taking your router out of the path to see if the problem goes away?

Sounds like the IMAP server is attempting to IDENT the connection. If the router is configured to *DROP* TCP requests on port 113, you can see slow startup times if the service making the request has a long timeout configured for the ident response.

The correct fix for this is to configure the router to REJECT connections on port 113.

A "jack legged" fix would be to port forward TCP/113 to your workstation. Your workstation should refuse or accept connects on port 113, but not drop them.

OK, but I don't see how to do that on this router.

Filter IDENT(Port 113) was enabled. I tried disabling it and still get the delays.

I'm now trying to filter port addresses and setting it to 113.

Wow, this has been happening to me also since I got the RT31P2.

So far it's just been one lovely surprise after another with Vonage.

Try disabling the "filter" for port 113. After the router is updated, reboot it.

Which should I disable?

"Filter IDENT (Port 113)" or "Filter port range" where I enter 113?

I've already tried the former with no success. The latter I just did before going to bed last night. We'll see how that goes.

This is kind of getting off-topic a bit, but it started as a potential problem with the Linksys/Cisco Voip device and I am not convinced that's not a factor yet.

My D-Link wireless router has an option to "deny", which I tried for port 113. That just made it impossible to connect to my email server. I did not try filtering packets on that port, but read on.

I left out one important detail about my setup in my previous post. The machines I am having trouble with are configured to access the email server via its external IP address rather than via the internal (LAN) address. Dumb as that may sound, they are laptop computers that I also use on the road to get my email. I have them setup to do email externally so I don't have to keep changing the settings.

In the same timeframe as getting the Linksys/Cisco Voip appliance I also upgraded the firmware in the D-link router. So I suppose it's possible there is some new "feature" that is causing this failure. One of the new firmware features is dynamic DNS, which I was using in the email settings on one of the laptops. I don't suspect this because the IMAP problem seems to occur whether I use the dynamically assigned domain name or just the plain IP address. But there could be other changes to the firmware that are at play here.

Is it possible the email server is having trouble with IDENT because the client machine is connecting it to on an external IP address but "lives" on the same LAN and the router is now dealing with that differently than it did before? Note that for external access, only the secure IMAP port is mapped in the router. Also, I use a nonstandard port for SMTP on the router and map that to the standard port 25 on the email server.

I don't know much about packet switching and all that stuff, no more than I need to know to configure and maintain (and protect) a simple home network. Any help would be greatly appreciated. I still think the Voip device has something to do with this, but I don't know enough about how it works to determine what.

Thanks,
Bruce

Bruce,

This seems totally on-topic here. My LinkSys router is definitely the problem, as the problem disappears when I take my router off-line and just use my old wireless one.

I also have the dynamic routing feature, and it's disabled right now.

As an update, not using SSL didn't help my client.

Maybe I'll play with the routing settings (dynamic and static).
