Good morning,
I just realized that all the SMTP relay services have stopped working for quite some time, after reviewing the server logs. I thought emails were being sent correctly, but today a client who was waiting for a reply contacted me.
If I try to connect using simple telnet, I get stuck waiting on all the available ports (26, 587, 2525).
I hope this can be resolved as soon as possible.
I look forward to hearing from you.
Best regards,
Matteo
