SMTP connection timeout

Hi,
This question might sound naive, but I just couldn�t find the answer.
For POP, IMAP and HTTP it is easy to setup idle connection timeout (just use configutil).
But what about SMTP connections?
It is set by default on some value (if I just telent on port 25 and live the connection idle, the message �Connection to host lost� will appear after aproximetly 5 minutes), but I cannot find where it can be changed.
On the other hand, what if connection is not idle, but the user is trying to send a bit biger mail but the link is really slow� how is this treated, what is the timeout for this situation and where this can be changed?
Thanks a lot, as always :)

The thing I�m having on my mind is to set this timeout to bigger number, and let slow connections to stay alive for more than 10 minutes.
The only parameter I found is MAX_IDLE_TIME in dispatcher.cnf file, by default it is set to 600.
But the explanation for this parameter is a bit confusing:
MAX_IDLE_TIME=integer
Specifies the maximum idle time for a server process. When an server process has had no active connections for this period, it becomes eligible for shutdown. This option is only effective if there are more than the value of MIN_PROCS server processes currently in the Dispatcher's pool for this service.
Anyway, for testing purposes I set this parameter to 6000 instead of 600, and did:
./imsimta cnbuild
./imsimta restart
Again I telnet to port 25 and live the connection idle, the message �Connection to host lost� appear again after approximately 10 minutes), so it seems like nothing was changed.
So, is this the wrong parameter, or for some other reason time is not expanded?
Btw,

Weblogic smtp connection timeout!

Hi, when I deployed my program in the weblogic server, everything is ok, but after somedays it can not send mail! I believe my code is available, because I can send mail in my tomcat server in the same machine. Can anyone help me or give me some clue?
Thanks a lot!

Just to be clear, you work for BEA, you're using WebLogic, you're trying
to send mail using the smtp.bea.com mail server, and you're asking for
help here? :-)
Assuming the server isn't actually down, and connections aren't timing out
when connecting from other applications or other machines, I would look
into whether there's a firewall that might be preventing you from connecting,
or possibly the mail server has decided that you've connected too often or
have too many open connections and so won't let you connect again.

How to change the SMTP connection timeout in Thunderbird?

Go to Config Editor
(Tools | Options, select the Advanced panel, select the General tab, and click Config Editor)
and ...
Which parameter need to change?
If I connect to the Internet as:
Computer -> WiFi Router -> 3G Modem -> Internet
then Ping time is big, and OFTEN (but not always) there is an
"Sending of message failed. The message could not be sent because the connection to SMTP server mail.domain TIMED OUT".

Then what other software do you have that fills a security role or what setting on the router or modem need fixing. I use a wifi router and 3G box at work and while the service is not great it does function and ping times are quite reasonable (we are on the out limits of the 3G coverage 1 or 2 bars)

Connect timeout for InitialDirContext creation doesn't always work

Hi,
I've got a problem with the InitialDirContext creation timeout settings.
If I set com.sun.jndi.ldap.connect.timeout=5000, and I "mistype" the connection URL to something non-existent, or the port to something where nothing is listening, then this timeout kicks in, and the InitialDirContext creation fails (this is good so far).
However, if I set the URL to port 25 (for example), where another service (in this case SMTP) is listening, then the InitialDirContext creation will hang for ever waiting for a valid ldap response to the login request.
What other timeouts could I set for jndi to avoid this?
I've seen that this bug (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4410856) was closed as fixed, but I don't think it's really fixed (or if it is, I haven't found what the correct procedure would be to fix this issue)
java version is:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)
thanks for any help,
regards,
mitch

"The Sun SMTP Transport service failed to deliver the message to this recipient on server smtp.vera.be for the following reason: 1 SMTP connection broken (command)"

how could I troubleshoot this problem? i really don't know what is going on.Let's start with -- what email client are you using?
Based on the error message I would guess this is Outlook running the Sun Outlook Connector.
What versions of Messaging Server (./imsimta version) and Outlook Connector are you running?
What was different about this particular message -- was it a large email, was the email sent from home (slow internet link etc.), was it to a particular problem user?
Can they reproduce this error?
Did you have MTA problems at the time, can you see the matching connection attempt in your mail.log_current?
Outlook Connector has a default 60 second timeout when attempting to delivery an email. If this timeout is exceeded the connection will be dropped and the customer will see this message. The following registry setting controls the timeout:
"HKEY_CURRENT_USER\Software\Sun Microsystems\Outlook Connector\Connection Time Out"

Is there a risk of setting a console connection timeout and what is the recommended setting?

Is there a risk of setting a console connection timeout and what is the recommended setting? Please suggest if there is any best prctice documentation that can be referred.

Hi Henrik
depend on what you need or what your security policy says for my lab gear i use 60 minutes. because i know how can access this. if you have gear outside in insecure space set it to a minimum or disable the console. everybody how can access your gear can break in. simple restart and boot w/o config. and you are in.
it realy depends how secure is your space and how much security you need.
and than the settings for policy have to match, what sec do you have if your console login and logout is secure. but when you restart you can simple break in by starting w/o config and than load it.

I am getting a "connection timeout" message when trying to access my Airport Extreme with various laptops, Play Station 3 and Wii. My Airport Extreme is about a month old; it was working fine until about a week ago. Suddenly, the "timeout" is not allowing me to connect to my wireless network.

It could be that there's a new source of interference.
Use the advice in the second message of this thread to investigate the signal and noise levels that each client sees:

Why do I keep getting a "connection timeout" error on my macbook pro?

What seems to be on some kind of time schedule, my network connection times out. The message "a connection timeout occured" is displayed, rendering my attempts at re-connection useless. After hours of troubleshooting(my router included) and checking out other Mac forums, I have no solutions but to power cycle my router. This pretty much makes my MB useless unless using a wired internet connection outside of my home network. I've done tons of research online and have encountered hundreds of people with the same problem. My machine is a late 2011 Macbook Pro. PLEASE HELP

Time Capsule woes -- Connection timeouts and can't connect with one Macbook

This is my second Time Capsule. Here's the scenario:
I have a Netopia 3347 DSL modem. That feeds into the Time Capsule in bridge mode. There is a MacBook (metal case), iBook (yes, it's old), two iphones, a color printer and an iPad that can all connect to the Time Capsule just fine. The problem is my MacBook can't connect. The offending computer is a 2.2Ghz Intel Core 2 Duo running SL 10.6.6. This computer can connect to the Netopia just fine, so I know its internal Airport works. After several go arounds with Apple tech support, I'm still nowhere.
Here are the symptoms:
1. I can see the TC's network SSID in the airport pull down menu. If I select the TC, a popup appears and asks for a password. If I enter the password, I'll get a connection timeout error.
2. On the rare occasions where it does connect, I can't open a webpage. Network diagnostics has red dots for ISP Internet and Server
3. On the even rarer occasions where it does connect, and I can access a webpage, it's unbearably slow, and the no-surf problem reappears after a few seconds. The red dots on the Network Diagnostics reappear.
Apple tech support was not helpful. I've power cycled everything a million times (and that doesn't explain why other computers can connect.) I know it's not my computer, because it can connect to the Netopia just fine.
I am STUMPED.

Magnificent! Problem solved... Isn't there a "this solved my problem" button somewhere?? Thanks and thanks again!

Connection Timeout after updating to 10.6.6

Dear Friends
I've got Macbook Pro mid 2010, when I was on 10.6.5 there was no problem connecting to Wi-Fi but after the magic update, I always got "Connection Timeout". another thing to add, I can connect to any network via windows 7 I installed on my macbook.

My two cents is that I have had some type of network problem since install Snow Leopard. I even went back wiped drive and did clean install. Seems their is a problem but not sure if its multiple problems or just one. Safari seems to load pages at a crawl at times. I did several speed tests and found the WIFI connection noticeably slower (about half) compared to my Windows Vista computers running WIFI. Even though my MacBook has N version connection and the Vista ones G.
I have tried different DNS servers and nothing seems to help. The router is the second one I tried. I had a Linksys wrt54 then bought a Belkin F5d8236-4 and both have no effect on the problem. Even a different browser did not help. I have simply determined that Apple needs to fix something in Snow leopard.

Connection timeout on hotel wifi - only with MacBook8.1 (810.9) configd plug-in:8.1 (810.9)

I'm having a "Connection Timeout" issue while trying to connect to my hotel's WIFI.
I bought an ex-lease refurbished white MacBook (Build 12E55 - 2.4GHz, the last 2010 model I think) a couple of weeks ago. I bought it so I could use it while on vacation in Bali, Indonesia. I've got OS X 10..8.4 installed.
At home in Australia, this MacBook connected to my home WIFI with absolutely no issues at all.
Now that I'm in Bali, I'm surprised to find that every time I try to connect to the WIFI at the hotel (where I'm staying for a whole month), I get a "Connection Timeout" error. I'm surprised because my iPhone connects to the hotel WIFI with no problem at all, as does our two iPads and the Android phones that belong to other family members. It's only my MacBook that struggles, even though I get even better signal strength indicated on my MacBook compared to my other devices.
I can connect my MacBook to my iPhone hotspot fine, though I'd prefer to use the free hotel WIFI over my very small 3G data allowance.
So the problem isn't that my MacBook can't connect to any WIFI, because it did at home and it still can to my iPhone hotspot.
And the problem isn't with the router, because all other devices work flawlessly.
I've trawled many forums and articles trying to find a solution. Here's everything I've tried already, that I can remember. (Not in this order and not all at once.)
Rebooted MacBook (duh)
Sitting directly under the WIFI router. (It's not a signal strength issue.)
Set up new Network > Location. Deleted Ethernet and Bluetooth PAN so it's just WIFI in the list.
Renewed DHCP Lease countless times.
Tried manual TCP/IP variations. It doesn't help that I'm not sure what to put in the IPv4 Address field. I do know the Subnet Mask and Router IP from looking at my iPhone network info.
Tried using my MAC address as the DHCP Client ID. Also tried just using "1" or leaving it blank.
I don't know what an IPv6 is either.
Tried BootP and completely Manual setups but not really sure of the correct settings to try.
Tried using the DNS servers that I found on my iPhone network info for the hotel WIFI. (One of them is 8.8.8.8 which I think is Google's DNS thing?)
Tried checking Auto Proxy Discovery and Use Passive FTP Mode, since it was suggested as part of a solution in a forum thread.
Tried changing the MTU to a couple of other settings from an article I read. I think one was around 1453 and the other was 1494 or something close to that.
Tried resetting PRAM
Tried resetting SMC
Tried a variation on resetting SMC that involved pressing down the normal keys plus one extra, for 10 secs, since it worked for someone who was told to do that by an Apple Care person. (He didn't know why it worked and other forum posters thought it was supposed to have been a SMC reset.)
Checked the Network> Wi-Fi in System Information to see if the Channel is compatible. The router uses Channel 1 and my MacBook is capable of using Channel 1.
Checked my country profile. It's X1. I have no idea if that's good. All I know is that I'm in Indonesia not Australia and I'm having WIFI issues with this hotel network.
Checked the PHY Mode. Supported are 802.11 a/b/g/n. The hotel router uses 802.11n.
Made sure I was using WPA2 Personal.
Tried deleting all WIFI-related passwords in Keychain.
Tried deleting all Network-related preference files.
Tried removing all LaunchDaemons and LaunchAgents.
It's not a "lost WIFI connection when waking from sleep" issue but I tried turning off sleep anyway.
My husband even had the nerve to unplug the hotel router (small hotel, we're the only guests at the moment) for 10 minutes hoping it will reboot. But I don't know if that's the actual modem or just a WIFI repeater thing (sorry, can't remember the right terms). It didn't work anyway.
I've run out of options, other than just sucking it up and getting a big 3G data allowance since I'm here for a month.
If there is anything else I can try - perhaps working out how to set up my Network manually properly, please help me out. Here is everything in System Information that might help. I'll happily provide any other info.
Software Versions:
CoreWLAN:

Sorry. The topic title got mucked up when I tried to paste in my System Information. And I can't paste it in using my iPhone without it going haywire. I can provide any details you need.

Is there a way to control the number of concurrent SMTP connections on Database Mail?

Las week Rackspace started controlling the number of concurrent SMTP connections and we are now getting the following message when we send as little as 15 messages at a time using Database Mail:
Exception Message: Cannot send mails to mail server. (Service not available, closing transmission channel. The server response was: 4.7.0 smtp13.relay.dfw1a.emailsrvr.com Error: too many connections from IP xxx.xxx.xxx.xxx)
We are using SQL Server 2005 and Windows 2003 and we have been doing this since 2006 with no problems
Is there a way to control the number of concurrent SMTP connections used by Database Mail or the Database Mail external executable DatabaseMail90.exe?

Hi rkohler,
Usually, we can use the Database Mail Configuration Wizard or the Database Mail stored procedures to determine the server name and port number for the Simple Mail Transfer Protocol (SMTP) server . In the SMTP server points, we can set or increase the number
of concurrent connections.
There is similar issue about database email on SQL Server 2005, you can refer to the following post.

Why do i keep getting the "internet connection timeout" error message?

i have been upgrading a few standard itunes albums to itunes plus versions through my 3g mobile broadband connection, while not exactly a fast process, it was working fine until i started to get a backlog of 3 or 4 albums which were waiting in a queue to be downloaded, now every time i do the "check for downloads" option i get the "internet connection timed out" error message...this has been going on for 2 days! am i right in suspecting the backlog of albums is too much for my 3g mobile broadband connection? this is really doing my head in, if any of you techies could help me, it'd be much appreciated...?

yes i have recently updated to itunes 8.2.1, but i am starting to think its apple's servers (i tried to download at my brothers house...different computer and connection...same connection timeout error), because it will still let me download an album, but not necessarily all of the tracks. when i questioned itunes customer services about the seemingly hit and miss state of affairs with downloading, they told me to wait 3 weeks before trying to download the tracks that were giving me the grief (2 tracks from an arctic monkeys album)...which kinda indicates they know there is a problem and are trying to fix it, why else would they say wait 3 wks??? they gave me 5 free music tracks too, which is handy.
