Using SMTP server

Hi
i am using tomcat-apache to send a mail from a jsp-servlet
everything is fine with the code, but i am suspecting the settings of smtp server,
i got this error:
ENCOUNTERED EXCEPTION: javax.mail.SendFailedException: Sending failed; nested exception is: class javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25; nested exception is: java.net.ConnectException: Connection refused: connect

**it was more but i trimmed it**
can any one help me to set up a smtp server and how to use it in my program, i know very little about smtp server
thanks
siv.

It looked like you might have got the hostname wrong
// set up the session properties
Properties props = new Properties();
// find out the host name from you system admin
props.put("mail.smtp.host", HOSTNAME);

SMICM error while sending mail using SMTP server

Hi All,
We are not able send mails using SMTP server.
We have made every settings necessary in SCOT, SO16 , SMTP service is activated, default domain is maintained etc
Only things which seems to be wrong is in SMICM trace file.
[Thr 13] *** ERROR => NiBufIConnect: non-buffered connect pending after 5000ms (hdl 29;10.26.24.44:1090) [nibuf.cpp 4608]
[Thr 13] *** WARNING => Connection request from (0/1/0) to host: 10.26.24.44, service: 1090 failed (NIECONN_REFUSED)
[icxxconn_mt.c 2321]
This error is getting repeated in it.
BUt I am not sure why it it trying to hit 10.26.24.44, as we dont have any server by this ip. The ip is only not resolvable from the server.
1 more thing, at OS level, following parameter is maintained in profile :
icm/server_port_1 = PROT=SMTP,PORT=25000,TIMEOUT=180
But in SCOT, under SMTP node PORT is given as 25.
Kindly let me know what going wrong here?
Thanks

Can someone help me send mail using SMTP server?

I am having the most frustrating problem with SMTP outgoing email account. I use GoDaddy's Webmail (smtp.secureserver.net) and I receive all my emails through Apple Mail but I cannot send any. I haven't been able to for about two weeks now, aside from 3 or 4 fleeting windows of time when I could. Almost all of the time I try to send my emails, an error message says my outgoing account is offline. I've been on the phone with GoDaddy's tech support three times this week and did everything we could think of, which include these steps:
-Force Quit Apple Mail --> Restart Computer
-Change Default Ports to a specific one and uncheck "Use Secure Sockets Layer (SSL)"
-Check "Use only this server"
-Delete account completely from Apple Mail and re-load (which I had to go into Time Machine to recover messages, and lots a bunch in the process ugh!)
Nothing works! I depend on this email for my business, and I rely heavily on Apple Mail for this account. All of my other email accounts that I pull through Mail work fine, but of course they are not SMTP outgoing. Please help...I feel like I've tried everything and nothing works permanently.

At this point there are 2 possible causes to your problem:
Apple Mail
Connectivity between you and the SMTP server
I can't help with (1) as I use Thunderbird as my mail client (the biggest advantage being I can take my mail files and move between different versions of Mac OS X). If you suspect that your problem is due to Apple Mail, then using another email client to send a test message will prove the point. If it works, then the problem lies with Apple Mail and somebody else will have to chip in. If it still fails, then there may be connectivity issue between you and the mail server.
If you google "telnet smtp test" (without the quotes), you will find many articles showing you how to test an SMTP connection using telnet. Don't be put off by the fact that many of the articles assume you are running Windows. The only Mac bit you need to know is that telnet is a command line utility accessed via Terminal. The rest is generic.
Telnet will allow you to interact with the mail server a line at a time and show you exactly what and where the problem is. If you get an unexpected response from the server, go back to GoDaddy and show them the output. If you don't get any response at all (i.e. "telnet smtpout.secureserver.net 25" just hangs), then take it up with your ISP as you are simply not getting through to the server.
Good luck.

also i want to know whethr i can use that our smtp server from a computer outside of the net work.
pls help me
txs lot.

Almost certainly, if you are behind a proxy server it will only be a proxy for HTTP traffic, and you will not be able to communicate with an SMTP server outside your network. But you have your own SMTP server so why would you want to?
If you have a proxy server and an SMTP server then there will be people responsible for supporting them. Talk to those people and ask them to give you the basic explanation of networking that you need.

Problems using smtp server in Mail

Hi, I'm using Mail on my iMac (Leopard) with a POP account for my incoming mail, and an smtp-server for the outgoing mails. Everything works fine.
Now I've also bought a new MacBook. I setup the Mail account exactly the same as on the iMac. I can recieve mails, but not send them? When I use Connection Doctor in Mail I get green markers for both incoming and outgoing servers. It says that the connection with the smtp server is fine. Still when I try to send mail it gets stuck in "Sending...", no error messages, nothing.
When I go back to the iMac, I can still send without problems.
Anyone have any solutions?
I can add that if I connect my 3G module for mobile internet to the MacBook and change the smtp server accordingly to that service provider, it sends mail without problems.

UPDATE: I was able to set up the account using Eudora, and it worked fine. I guess it means that there's something funny happing with Mail.

Cannot send messages since updating to Thunderbird V 31.3.0. The message could not be sent using SMTP server for an unknown reason. Help?!?

Mail provider - Network Solutions
ISP - Comcast
Anti-Virus - Kaspersky Internet Security 2013
OS - Windows 7 Home Premium, Service Pack 1
Outgoing Server SMTP settings attached.
I can receive messages and can send them directly from Network Solutions just unable to send now from Thunderbird. Was working fine until the newest version installed. Haven't changed any settings...

That anti virus? is it Nortons security suite? I think that is what comcast give their xfinity customers but I am not sure what everyone else gets.
Assuming is is the Norton's product go into the firewall component and explicitly allow Thunderbird unrestricted access to the internet. Norton's product have a long history of blocking new releases of mail programs because the version number changed.
Go onto the SMTP setting you have in the image and make sure each has a description entered.
Now check in the account settings by clicking the account name in the list so you select the item about Server settings for each account and make sure the selected SMTP server is what you think it is. Now there is a description that will show in the list.

Probe from the SMTP server

When sending a message using SMTP server how to find the appropriate SMTP server given the e-mail address ?
for example if I try to send an e-mail to this address
[email protected]
How do I find the name of the smtp server associated with the "someserver.com". I tried using
smtp.someserver.com but it did not work for all servers.

Just to add to this, after you query the DNS server, it may return you a whole set of ip addresses with priorities. You must start with the highest priority and go ahead.

With Mail 8.0, the SMTP server selection list has gone?!

Hi,
I use one primary IMAP email account, but multiple addresses, and I have to send my emails using different SMTP servers, according to the email address domains. Now, before updating to OS X 10.10 Yosemite, in the New Mail window, there always was a "Send Using" SMTP server selector right next to the email address selector. Now that's gone, and I can't figure out how to bring it back.
So now I'm unable to send email using other than my primary domain address.
Any ideas?
In fact, if someone could tell me how to directly assign a specific SMTP server to an email address (not to an email account! Remember: I have multiple addresses in one account) - that would be of great help, too.
Thanks much in advance!

I too would like to have the option of being able to select which smtp server to use for each email. Often when I am at a client location I have to use my tethered cellphone for network connection and this requires a specific telco smtp server to be used. Currently now there is a wait while Mail tries a few times with the primary smtp server associated with the account (my normal provider I reach when at home on the broadband) and some indeterminate time later it decides to poll the next server on the list (the telco one). Once it has done this successfully once then further emails seem to get routed immediately to the current smtp server. But the first time each day is a lottery on how long it will take.

HT4519 How do I use one smtp server for multiple accounts?

I have 5 email accounts on my iPhone.Though they are different providers, I've been using the same smtp server. To simplify my life, I'd like to delete 4 servers. However, each is considered a Primary server and is undeletable. How do I get around this?

How to send email to a SMTP server over a secure channel using STARTTLS setting of a send connector (Exchange and SMTP server are in the same domain)

I’m trying to send email using exchange send connector STARTTLS setting to the SMTP server. I have read multiple documents on configuring TLS for send connector, but they talks about outbound connections to internet facing servers. My Exchange 2013 and SMTP
server is in the same domain (let’s say A.com) and I’m creating dummy domains on my SMTP server (e.g.
[email protected],
[email protected] ) and their respective send connectors on the exchange server end. In the smart host section added the IP address of the SMTP server and in the scoping section added the SMTP domain address (e.g. dummy1.local ). In the FQDN field, added
the FQDN of the exchange server 2013 which certificate is enabled with SMTP service.
Could you tell me a step by step procedure, where I’m going wrong or any extra settings needs to added?
Presently, it is giving me an error that 530 5.5.1 TLS encrypted connection is required.
Note: I’ve created the Microsoft CA certificates for the SMTP and exchange servers and imported them in the personal certificate container. In which, the exchange certificate is created with FQDN name of the server and enabled for the SMTP service.
I’m using OPENSSL certificate for making the SMTP server TLS enabled. (let me know, if I need to import the OPENSSL certificate anywhere on the exchange end)?
Thanks!

-IgnoreSTARTTLS is set to false on the send connector properties.
I'm trying to established a HTTP over TLS connection. I'm not using mutual TLS between these two server.

Can port 25 be used for SSL-enable SMTP server ?

Hi,
Our customer is using port 25 for a SSL-enabled SMTP server without certificate. When our email client tried to connect to it, the following exception thrown:
DEBUG SMTP: exception reading response: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
Since we don't want to ask our customer to change their port configuration unless absolutely necessary, we did some tests with our own SSL-enabled SMTP server that uses certificate. Here is what I got:
1) with port 25, got the same exception as above;
2) with port 465, worked fine;
3) with any other randomly pick up valid port, worked fine.
This made me wonder if 25 is for non SSL SMTP server ONLY. By the way, I'm using Javamail 1.3.4 and JSDK 1.4.2_02. My question is whether we can configure javamail so that port 25 can be used by SSL-enabled SMTP server?
Your help will be appreciated.

Yes, port 25 is intended for non-SSL servers only, although that doesn't
prevent a client from making a plain text connection and then using the
STARTTLS command to switch the connection to SSL/TLS. JavaMail 1.4
supports that usage.
You can configure JavaMail to use port 25 for SSL connections if you
really want to. JavaMail 1.3.x requires you configure an appropriate
socket factory to get SSL connections; you can configure whatever port
you want for use with that socket factory.

I have multiple accounts using the same smtp server, I can only reply with one as the settings wont allow me 2 servers

I have tried to set my email to reply from my iphone 5 both of which use the same SMTP server. I can't change the settings on the others as it will only allow one mail account. Can I add multiple with the same smtp?

I Am not using gmail I use seperate company for my mails both use the same smtp server. The problem is when I set my first account it them uses these details and passwords when I create the second account saying that the smtp server is already in use by the primary account. I therefor can't set the password.

How to setup SMTP server in PC so as to send mails using JavaMail

Hi,
From forums i got it cleared that we can use JavaMail to send emails. I also got two sample codes about getting it done. But in the code its asks address of the host of SMTP server. I dont have any SMTP server. But i am writing a Library Application in which an email must be sent to users automatically when thier books are in overdue.
Where can i get SMTP server to be installed on my PC so that i can use it send mails through Javamail API.
Thanks
