I want to retrieve some e-mail informations from a Imap mail server.
I'm using Railo application server (not coldfusion).
After defining attributes values (serverURL,login and pswd) , I used the following instruction to open a connection:
<cfimap server = "#serverURL#" username = "#login#" action="open" password = "#pswd#" port='993'>
Unfotunately, it generates the following error:
Connection timed out: connect;
nested exception is:
java.net.ConnectException: Connection timed out: connect
java.net.ConnectException: Connection timed out: connect
As it says, connection timed out. Make sure that the url and ports are correct and, if the imap server is self hosted, to open port 993 as in the example on the imap server.
Also be aware that depending on how you authenticate / connect changes the default port that is used with IMAP.
The default ports for IMAP are:
Standard Port:143
Secure IMAP (IMAP4-SSL) Port:585
IMAP4 over SSL (IMAPS) Port:993
A easy way to test the credentials is to first connect a desktop mail client like Thunderbird or Apple Mail first. Then use those settings on the CFML Server.
Also sometimes the username requires the domain so even if the username is "john" you may have to authenticate with "john#yourdomain.com".

While trying to connect to SQLAnywhere (Sybase) database (C# code) from Azure ServiceFabric:
await using var connection = new SAConnection(connectionString);
await connection.OpenAsync();
receive iAnywhere.Data.SQLAnywhere.SAException
Connection error: Connection was dropped (may not be a SQL Anywhere server)
Error code is Error 832. This is generic connection error: An error occurred while attempting to establish a connection with the database server, but before attempting to connect to a database. Failure to initialize a communication link during the connection attempt is an example of this error. Creating a debug log file using the LogFile connection parameter may provide more information.
Locally it works, but does not work from Service Fabric.
Fix ideas tried:
Missing driver? Looks like no, Sybase (now SAP) SQLAnywhere requires special driver or client - but locally also works without this driver, just with iAnywhere.Data.SQLAnywhere.NETCore nupackage installed
Network connection/ firewall problems? Looks like no, database server can be pinged from Service Fabric node
It was another traffic protection tool. Although it was possible to telnet the port, still traffic from app was blocked by another tool.
Had a similar issue - turned out that whilst standard incoming traffic from the Sybase Server had been whitelisted in our Firewall, encrypted traffic from this had not been.
This meant I could ping and connect with Telnet, but got the same error when trying to log-in with my credentials
Connection error: Connection was dropped (may not be a SQL Anywhere server)
Our comms team solved the issue by whitelisted encrypted traffic from the server address as well. They also mentioned it possibly could have been solved we shared a valid security certificate for the encrypted data with their team, but were happy with the first course of action.
I have got a simple BizTalk Application in which there is only one schema and pipeline. I have simply add XML Validator in validate stage of pipeline.I have deployed this app in BizTalk Server 2010.
Now I have created a receive location which takes a XML file and set its receive pipeline which i have created. I have also marked "Enable routing for failed messaged" in receive port.
I have also created a SMTP send port and and configured it with mail server name and etc.
Receive port is working fine but send port is unable to send emails.
When i check "Track Service Instance" is shows an error "Transport failed to connect to the server".
Update: I am using Gmail SMTP server name in order to send e-mails and I am getting the error "The server rejected the sender address. The server response was: 530 5.7.0 Must issue a STARTTLS command first. ye1sm22267001pab.19 - gsmtp"
Where could be the problem? Any help will be appreciated
With that error in your update the problem is clear.
The Gmail server is expecting a SSL connection.
See SMTP TLS problem
The standard SMTP adapter does not support SSL/TLS connections.
You will need to write a custom adapter or purchase a third party
adapter to support SSL connections

Greg.Forsythe
EDIT: An alternative is to connect to a local SMTP server that doesn't require SSL/TLS and let it route the e-mails.
Are you running 32 bit or 64 bit? Is your tracking host in 32 bit or 64 bit? MIME/SMIME encoder pipeline can't run in 64 bit mode... are you using that?

"Transport failed to connect to the server"
This error message basically means the BizTalk SMTP adapter is unable to connect to the SMTP server or the server does not allow to send the e-mail.
Try connecting to the SMTP server with the telnet client (you may need to install this as an additional feature) or by configuring the proxy (available on the SMTP adapter and adapter defaults).
It might also be the case that you need to authenticate towards the SMTP server.
Also, some SMTP servers do not allow to send an e-mail from an unknown domain like "someone#notthenameofthecompany.com".
Hope this helps.
my application needs to send out emails to its users, but somehow I can't make it work. I have installed the SMTP server and in IIS I have set SMTP to use localhost, with port 25 without authentication. But when I try to send email, I am allways getting error
No connection could be made because the target machine actively refused it 127.0.0.1:25
When I choose the option to store email in directory, it works fine, so the problem isn't in my app. Why does this happen? The only thing I am thinking about, is if I need to have port 25 opened or not?
This would happen if you don't have an SMTP server listening on port 25.
I was wondering if there is a way to see if a server blocks outgoing connections. I am trying to connect to an external database from a client's server.
This is the error I get:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
Edit:
I forgot to say I only have access to the plesk control panel. That's why I was asking if there is a way with asp.net.
When you say "server", do you mean the asp.net server, or the SQL server? And are both machines on the same network? Is this hosted?
Sql Server:
They can remove the OPENROWSET functionality, so you can't connect to remote servers, regardless
I doubt they are giving you access to linked servers in a hosted env
ASP.Net
You can try to connect to the other server via a regular connection, and see if that works.
Download a tracert component, and use that to try to trace from your server to the remote one.
If it dies somewhere inside your network, then that is your answer (it is blocked)
If it works, the outbound is open. Doesn't mean 1433 is open though.
If it dies after, not blocked, but maybe the remote is blocking icmp echo
Remember to try to tracert to somewhere else that you know works
It will be hard to tell what is killing the connection on 1433, if you can get to the server using other means. Could be the firewall, their fw, etc.
The trusty telnet method:
telnet theserver 1433
If this times out, the server is not listening. If the screen blanks and you can type something, the server is listening and no firewall is blocking the connection.
In Vista and Windows 7, you have to install telnet as a Windows component from Control Panel -> Programs and Features.
I'm trying to configure a dedicated server that runs ASP.NET to send mail through the local IIS SMTP server but mail is getting stuck in the Queue folder and doesn't get delivered.
I'm using this code in an .aspx page to test:
<%# Page Language="C#" AutoEventWireup="true" %>
<% new System.Net.Mail.SmtpClient("localhost").Send("info#thedomain.com",
"jcarrascal#gmail.com", "testing...", "Hello, world.com"); %>
Then, I added the following to the Web.config file:
<system.net>
<mailSettings>
<smtp>
<network host="localhost"/>
</smtp>
</mailSettings>
</system.net>
In the IIS Manager I've changed the following in the properties of the "Default SMTP Virtual Server".
General: [X] Enable Logging
Access / Authentication: [X] Windows Integrated Authentication
Access / Relay Restrictions: (o) Only the list below, Granted 127.0.0.1
Delivery / Advanced: Fully qualified domain name = thedomain.com
Finally, I run the SMTPDiag.exe tool like this:
C:\>smtpdiag.exe info#thedomain.com jcarrascal#gmail.com

I'm using ASP.NET 2.0, Windows 2003 Server and the IIS that comes with it.
Can you tell me what else to change to fix the problem?
Thanks

This is a dedicated server that's why I'm installing the SMTP manually.
EDIT: I use exchange so its a little
different, but its called a smart host
in exchange, but in plain SMTP service
config i think its called something
else. Cant remember exactly the
setting name.
Thank you for pointing me at the Smart host field. Mail is getting delivered now.
In the Default SMTP Virtual Server properties, the Delivery tab, click Advanced and fill the "Smart host" field with the address that your provider gives you. In my case (GoDaddy) it was k2smtpout.secureserver.net.
More info here: http://help.godaddy.com/article/1283
I find the best thing usually depending on how much email there is, is to just forward the mail through your ISP's SMTP server. Less headaches. Looks like that's where you are having issues, from your SMTP to external servers, not asp.net to your SMTP.
Just have your SMTP server set to send it to your ISP, or you can configure asp.net to send to it.
EDIT: I use exchange so it's a little different, but it's called a smart host in exchange, but in plain SMTP service config I think it's called something else.
I can't remember exactly the setting name.
By the looks of things your firewall isn't letting SMTP (TCP port 25) out of your network.
two really obvious questions (just in case they haven't been covered)
1. has windows firewall been disabled?
2. do you have a personal/company firewall that is preventing your mail from being sent?
