I Have install dot project on linux machine. using ssmtp for gmail account to sending emails for mails notifications . but when i create any user it doesn't send mails to user email ID for account creation. but i send maail form shell prompt.the error i am getting is Failed to send email: 530 5.7.0 Must issue a STARTTLS command first. 22sm11794837wfd.6 added :( . Please help me if any one have solution....
Gmail requires a secure connection (TLS or SSL).
You need to configure SSMPT (not dotProject) to talk securely with Google's SMTP server.
I think you can just add the following to your ssmtp.conf file and (assuming your SSMTP package was compiled with SSL support) it should then work:
UseTLS=YES
Or perhaps:
UseSTARTTLS=YES
More info here.
I assume "530 5.7.0 Must issue a STARTTLS command first." means that you have to connect with TLS (Transport Layer Security). Does dot project support that?

I don't know if I am asking this in the right place.
I have an SSL cert for my website, and I am trying to setup a mail server (same domain) using the same cert.
I am using Postfix and Dovecot. When I try logging in from Evolution mail client, I get an error "Peer failed to perform TLS handshake". When I try an online service to verify I get "Recipient address rejected: User unknown in local recipient table."
I guess my actual question is, can I actually use the same SSL cert for my website and my email server?
What do I do to debug next?
You can use a certificate you have for the web server also for your mail server as long as it matches the hostname you use to access your mail server. Of course the certificate need to properly setup at the mail server, i.e. include the necessary intermediate certificates similar to how it is (hopefully) setup on the web server.
I am using Postfix and Dovecot.
This means you need to take care of multiple configurations, both for SMTP in Postfix and IMAP/POP3 (whatever you use) in Dovecot. And in all cases the certificates subject/SAN must match the hostname you use to connect to the server.
When I try logging in from Evolution mail client, I get an error "Peer failed to perform TLS handshake".
There are not enough information about this setup to find out what exactly is causing the TLS error. It is not even clear if the error is caused when retrieving mail (IMAP/POP3, i.e. Dovecot) or while sending (Postfix).
When I try an online service to verify I get "Recipient address rejected: User unknown in local recipient table."
This has nothing to do with TLS at all. The test server simply tried to use a recipient which your mail server (Postfix) will not accept.
What do I do to debug next?
The next steps would probably be to check if the certificate matches the names you use in the first place and to look into log files for error messages or warnings. Following steps depend on what the result of these steps is.
I can't seem to get outbound email working from my SugarCRM installation, with only the message SMTP connect() failed appearing in the logs.
I've set my smtp server to smtp.gmail.com, email address, password, TLS, port 587. When I go to 'Send Test Email' I get the error.
I've set my local hostname, installed openssl, set the host_name in config.php and included it as a referrer in config_override.php. I've also tried setting SMPTDebug to 2 in SugarPHPMail.php but that seemed to have no effect.
When I run openssl s_client -starttls smtp -crlf -connect smtp.gmail.com:587 the output includes Verify return code: 0 (ok) and I don't know where to go from here. I can connect via telnet to that host & port and get a 220 SMTP message back as expected.
I do also have an exchange server available, but haven't been able to get that one working either, and thought Gmail would be more easily-solved.
I'm on Sugar 6.5.26 hosted on Linux (Debian, Raspbian).
Ok I found the solution while looking for the 'Allow less secure apps' setting in Gmail.
I have two-step authentication switched on in my Gmail account, which will obviously complicate things but had slipped my mind. Therefore I needed to use an app-specific password, and not my normal Gmail password.
As soon as I created an app-specific password in Google (at https://myaccount.google.com/apppasswords) and plugged that into the SugarCRM settings, it worked fine. D'oh!
I am using google apps for email. I can send email out through c# code fine with smtp.gmail.com.
I would like to be able to use the name smtp.mydomain.com instead, but still have it go to smtp.gmail.com. I tried just seeing a CNAME in my DNS settings, but I get this error:
"The remote certificate is invalid according to the validation procedure."
Any ideas?
Thanks.
Yes, you can't, the TLS certificate used to communicate privately with the remote SMTP server is signed with smtp.gmail.com. The only solution is to create a SMTP relay with sendmail for example on your own server.
This is quite a specific question, and I have had no luck on the grails nabble forum, so I thought I would post here. I am using the grails mail plug-in, but I think my question is a general one about using authsmtp as an email gateway from my server.
I am having trouble sending mail from my app using authsmtp. I have installed and configured the mail plugin and was originally using my ISP's SMTP server to send mails. However when I deployed to AWS EC2 this failed because my elastic IP was blocked by the SMTP host. So I bought myself an authsmtp account and set up my server email address as an accepted one at authsmtp.
I then changed my configuration in SecurityConfig.groovy to point to the authsmtp server that I had been designated...
mailHost = "mail.authsmtp.com"
mailUsername = "myusername"
mailPassword = "mypassword"
mailProtocol = "smtp"
mailFrom = "valid-authsmtp-address#mydomain.com"
mailPort = 2525
...and I'm just trying to get this to work locally before I deploy back up to AWS. Sending mail fails and in my log I have this exception:
2010-02-13 10:59:44,218 [http-8080-1] ERROR service.EmailerService - Failed to send emails: Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 513 5.0.0 Your email system must authenticate before sending mail.
org.springframework.mail.MailSendException; nested exception details (1) are:
Failed message 1:
com.sun.mail.smtp.SMTPSendFailedException: 513 5.0.0 Your email system must authenticate before sending mail. at
com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)
at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:959)
at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:583)
I'm a bit lost since the username and password I provide in the
configuration are definitely correct.
A terse and not very helpful conversation with authsmtp support suggests
that I need to MD5 and/or base64 encode my credentials before sending, so my
question is in three parts...
1) any idea what's going on with the failure and why that message is
appearing?
2) how would I encode the credentials to pass to authsmtp and how would I
configure that for the mail plugin
3) has anyone successfully connected and sent mail through authsmtp from the
mail plugin and specifically from AWS EC2?
When sending Email using the Acegi plugin, under the hood a Spring JavaMailSenderImpl is used. Looking at its docs:
Note that the underlying JavaMail Session has to be configured with the property "mail.smtp.auth" set to true, else the specified password will not be sent to the mail server by the JavaMail runtime. If you are not explicitly passing in a Session to use, simply specify this setting via setJavaMailProperties(java.util.Properties).
So append to your SecurityConfig.groovy the following:
javaMailProperties = [ "mail.smtp.auth": true]
I didn't find a solution to this using the Grails mail plugin, so I'm still interested in an answer, however I did find a workround. It may be useful in case anyone else follows me down this lonely path.
I'm trying to make an SVN post-commit script that makes backups to a Gmail drive. Blat doesn't seem to support TLS. Are there any good scripting programs on windows that can send an email via TLS?
I don't know about other mail senders, but stunnel is able to accept a plain text connection and tunnel it through an SSL connection. You can have it listen on localhost:25 and make an SSL connection to an smtps server (tcp/465). I have used it in a similar situation where a WebDAV client didn't support SSL.
The blat folks are saying the stunnel is the best bet for tls support but i've found that gmail doesn't require tls to send mail. Now, the data may not be encrypted but I send out email via my account (to other gmail accounts only) all the time as an automated process and it works great. if you need it let me know and i'll drop in the command-line parms.
