Re: Can't send mail with smtpmail "any more". (Gmail and other providers)

[Vladimir Nikishkin]

I worked around this issue by switching to port 465+ssl/tls

It almost seems like port 587 got blackholed by something.

Debugging facilities did not illuminate the situation, the deadlock happens
before anything is written there.
