Can't send emails

Postby muzzatron on Mon May 01, 2017 7:47 pm

HI,
For some reason I can receive emails on my MacBook but not send them anymore. I don't think I have changed anything and am not sure why it is happening? Just wanted to check I hadn't messed anything up.

I am getting this message:

"Verify that you have addressed this message correctly. Check your SMTP server settings in Mail preferences and verify any advanced settings with your system administrator.

The server response was: SMTP-AUTH is not allowed on port 25

Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent."


I would appreciate any help!

Regards
muzzatron

Can you check and confirm the smtp server address set in your email client?

Can I PM someone screen grabs? :-)

From my email prefs I mean.

I don't have a Mac handy for screen shots, but refer to https://support.apple.com/en-au/HT203995

Use the values I posted in the SMTP section. SSL is no. Authentication is none.

Exetel checks that you are using an Exetel service for outgoing emails.

OK, so after some time scratching my head, and trying a few things. I turned off Authentication which was set to MD5 Challenge - Response.

Now I send emails again. Not sure what happened there. Don't ever recall changing it in anyway.

But glad it works now!! :-)

Turning off authentication as suggested by Dazzled seems to have worked on this. :D

Are you using mobile data or Exetel Internet connection in order to send / receive emails?

Please PM the service number where we can investigate your issue.

I am using exetel NBN to access the internet, I have just received an email from a friend that works in IT that uses Exetel and he is now suffering the same problem. I started a Ticket (#IKQ-19424-639) in the helpdesk last night.

The pop up looks like error 550 was received from the server.

I just sent an email typing in the terminal rather than a mail client so I could see all messages coming from the server.
That is -
telnet smtp.nsw.exemail.com.au 25
Using commands HELO, MAIL FROM:, RCPT TO:, DATA, and QUIT.
All returns (except DATA) were 250 OK, so the server is working correctly for me.

(DATA returns "354 Enter message, ending with "." on a line by itself")
Underneath the GUI on your screen, all mail clients are typing away like this on port 25 to send and port 110 to receive. If you can connect this way, the trouble is in a client setting. Windows users may have to enable telnet first.

This applies to non-mobile services for SMTP (sending).

Sorry Dazzled, I am not conversant with sending emails via terminal, I will have to do some learning to use the commands. Cheers
