Hi, I'm experiencing a weird problem which is preventing emails from a particular client. The client mentions they're able to send emails to other companys apart from ours so there must be a problem with the connection between these two companies.
Below are a couple of errors bouncing back to the senders -
----- The following addresses had permanent fatal errors ----- <richard.davis@xxxxxxx.co.uk>
----- Transcript of session follows ----- <richard.davis@xxxxxxx.co.uk>... Deferred: Bad file number Message could not be delivered for 3 days Message will be deleted from queue ========
And
Your document: mail test
was not delivered to: test.user@xxxxxxx.co.uk
because: 451 Remote connection lost - psmtp
One thing I do know is that the company who sends the email send using TLS connections. However our ISP tells me we're able to recieve TLS emails.
Further troubleshooting has revealed that our email systems do not seem to allow the Postini servers which deliver outbound mail from the client to connect to our email servers via TLS, which produces the error.
The sender said they have run some tests and these are the results -
I sent a mail to the address you listed, In the Postini outbound routed case the message failed on STARTTLS, on the direct send the STARTTLS failed and the server reverted back to standard SMTP transmission. By the way GMAIL and Yahoo probably don't send TLS which could explain why they work.
