[GTALUG] accessing smtp server with weak dh encryption?

Matt Price a écrit profondement:


| I use the u of t smtp servers for outgoing mail from my laptop, including
| some automated mails that I send out.  Postfix's sendmail will no longer
| complete the TLS handshake with the server, because the U of T server
| hasn't been updated to fix the logjam attack (still using a 512kb temporary
| key).  Current thunderbird breaks, too, though if I use an old version I
| can still get mail out.

| Does anyone know if there's any way to instruct postfix (or is it maybe
| openssl) to violate protocol and permit me to interact with this server? I
| know there are security risks but I'm kind of screwed if I can't send out
| mail.

I had outbound problems, some very similar to yours

If all else fails, you don't have to actually be a spammer (and
I'm not) but "SendGrid" will punch your ticket for free if you
send less than 400 emails a day. 

They seem able to send anything to anybody with access to the
disposition of the email if you should need it.

Looking at inbound headers  too, I notice a couple of well known
reputable companies using SendGrid.
