[Astlinux-users] Cannot send mail from Astlinux

[Michael K. <mic...@ip...>]

Hi Group

I have a site that I cannot send mail from yet it is configured exactly the same, with the same Astlinux version as many others that are working to the same mail server (Office 365).
I get ‘msmtp: the server does not support TLS via the STARTTLS command msmtp: could not send mail (account default from /etc/msmtprc)‘

Now it is sitting behind a firewall with a bit of intelligence (or not) so I'm wondering if it is blocking something related to the TLS setup.

Any ideas?
