Re: Dynamically switching send-mail settings

Hi Tory and all,

Do you still remember how you managed to fix this particular issue? I
know its been quite a while, but I've started to get a similar issue
which I supposed is caused by what Lars suggested, that the SMTP server
(Gmail) is closing the connection. I could provide some more details of
my setup to help understand what's going on, but I get the following
message:

gnutls.el: (err=[-15] An unexpected TLS packet was received.) boot: (:priority NORMAL:%DUMBFW :hostname smtp.gmail.com :loglevel 0 :min-prime-bits nil :trustfiles (/etc/ssl/certs/ca-certificates.crt) :crlfiles nil :keylist nil :verify-flags nil :verify-error nil :callbacks nil)

and, with `smtpmail-debug-info' and `smtpmail-debug-verb' both set to
`t', I get the following messages in the trace buffer:

smtp.gmail.com ESMTP a6-20020a170902ecc600b001e45c0d6ce6sm1531247plh.306 - gsmtp

Process smtpmail<10> connection broken by remote peer

I don't know why it is closing the connection, or how to tell
smtpmail.el to close the connection after some time. It isn't stopping
me from sending emails, but it is quite bothersome to have that popup on
my echo area from time to time...
