I am trying to read emails from a Guerilla Mail account that has 'expired'
–Based on the Guerrilla Mail documentation, past email addresses are not reused or destroyed, so they should be accessible:
"all addresses work all the time, they never expire"
–Guides like this try to give instruction on how to Telnet into a mail server, but at least on OSX, commands such as 'user' and 'pass' are not recognised, and Guerrilla Mail server at mail.guerrillamail.com does not recognise commands such as AUTH LOGIN.

How do these online services of spoof email work?
They usually require the from domain really exists. It means there is a smtp server which accepts the connection.
Let's say I send a mail from test#xxx.com. The site will try to connect to the xxx.com smtp server and it will deliver the message.
The questions are:
How it is able to find the xxx.com domain smtp server?
To correctly deliver the message, xxx.com has to be without authentication. However, also with a fake gmail.com domain, the email is correctly sent, even though Gmail requires auth.
I have just installed VestaCP on a fresh CentOS VPS.
I have set up email for one domain. All mail sent to that domain bounces with the error 550 smtp auth requried
I have commented out the following;
deny message = smtp auth requried
from exim.conf
I have turned off anti-spam.
I still get the bounce with this message.
Specifically, if I send an email from a gmail account google responds:
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain foobar.tld by mail.foobar.tld. [x.x.x.x].
The error that the other server returned was:
550 smtp auth requried
Any experience with this? I have seen the problem on a number of threads but have not found a solution.
I partially solved the problem. It only occurred when sending mail to the smtp server from a domain that was hosted on the same server for web but not for email. When I sent email from a domain that had nothing to do with any domains hosted on the same server as the exim instance, then it got through. I still can't send email from the domain that was causing the problem and I would like to, but I can work around it.
So to be clear in case anyone reads this:
domain1 web is hosted on server1
domain1 email is hosted on google's servers
domain2 is hosted on server1 for web and email
exim is running on server1
when I send email from thunderbird via google's server from email#domain1 to and email#domain2 the exim instance asks google's smtp server for authentication even though the mail is being delivered to a mailbox in its list of domains it can deliver to on the same physical server where it is running.
I suspect that it is suspicious of the from address, which it shouldn't be since the mx records indicate that it does not host mail for that domain.
There is lots of posts with users having same error, but none of them works for me...
I am trying to send email reports in Hudson/Jenkins...
Our mail server uses SSL/TLS, I configured Jenkins for TLS, then I am getting this error:
Client does not have permissions to send as this sender
When I try javamail using code, it sends the email properly. Also, Thunderbird works fine.
Any ideas? Do I need to contact mail server administrators?
Finally got it, thanks to Friso
Had to set my email address in System Admin e-mail address under Jenkins Location.
The email should be changed in three places as below as per version 2.19.4:
Extended E-mail Notification - If using SMTP plugin
Email Notification - SMTP Authentication
Jenkins location - System Admin e-mail address
I had the same issue, and I discovered that credentials were no more valid, so I asked to the IT department who told me that credentials were no more need on LAN.
Now it works!
I have built a site where users can send out messages to other users with similar interests, this is done with smtp on iis6, soon to be iis7.
WHat Im finding though is that every now an then messages dont get through to SOME users with hotmail accounts. Is this something I can sort via iis?
thanks
Check the undelivered mail folder on your SMTP Server. IF the hotmail messages are there then hotmail is refusing delivery from your mail server.
The undelivered aka bounced email folder may also contain delivery notifications if your admin mail forwarding is not setup properly. These will provide more direct information as to the cause of failure.
If both of these fail, setup a script to send a message to a hotmail account and then retrieve it. When the test message fails to be retrieved, the script can then capture DNS resolver cache and other useful info to give you a hint as to what went wrong.
This is the issue. I've a postfix mail server which has external email accounts (that exists on both my mailserver and my ISP) and internal use accounts (that only exists on my local mailserver).
The problem is when a local account tries to send an email to another local account which has a forward e-mail address configured. As the local account (the one who sends) has no authentication due to the lack of the ISP account, an error return everytime the only-local account sends an email to another local account which has an external forward configured.
Is there a way to avoid this behaviour? I don't want tons and tons of email-errors flushing back to the user's account.
In your /etc/postfix/main.cf change the value of 'mydestination' to nothing ie ''
and 'virtual_alias_maps' to nothing ie ''
