I have to say I've seen this and I posted about it back in January. https://sourceforge.net/p/assp/mailman/message/34783916/
Back then I saw problems with Gmail, Yahoo Mail and SMTPRoutes. Since then I've occasionally fielded calls from different people saying that emails aren't coming through and the solution has been to add the IP to noTLSip. The problem was much more significant back in January because I was getting lots of complaints whereas now it is only occasional. I'm on a completely different architecture to you. Ubuntu 14.04.4 LTS, OpenSSL 1.0.1f (latest from apt), Perl v5.18.2, Net::SSLeay 1.74, IO::Socket::SSL 2.033, Net::SMTP::SSL 1.03 I've been using cpanm and cpanoutdated to manage module updates, checking from within cpan I can see that a number of modules haven't been done that way so I'm running upgrade from within CPAN itself to get things up to date. One of the updates is Net:SSLeay 1.77 so I'll see what that does. All the best, Colin Waring.

As it turns out, my conclusion appears to have been wrong. - There are some SLOW servers outside that are just plain slow (nothing I can do there), - TLS seems to work reasonably fast with most inbound mail, though significantly slower than without TLS (5 seconds for an 11mb file without tls, vs 45 seconds with TLS on) - GMAIL.com inbound TLS emails are SLOW, no matter what settings I tweak With inbound gmail.com message. if I have TLS off, an 11mb attachment is delivered through ASSP in under 5 seconds. With TLS on it takes close to 10 minutes, which gets close to gmail's limit. I've tested with Outlook.com and that same 11mb attachment comes in through ASSP with TLS on in about 45 seconds. Sending a 30mb attachment from gmail FAILS because it takes too long. gmail will try for I believe 10 minutes to send a message, then it quits and retries. After a couple tries, it sends an NDR. This is a Windows 2012 R2 server, latest ASSP dev, OpenSSL 1.0.2h installed from slproweb.com/products/Win32OpenSSL.html (though I've also tried with the OpenSSL I downloaded a while back from the ASSP sourceforge site. net::ssleay 1.74 (openssl 1.0.2g). I'm almost certain that the OpenSSL installation is not used by ASSP, but I've not been able to get confirmation of that here. Just updated IO::Socket::SSL to 2.033. Net::SMTP:SSL 1.02. CPU usage as reported by assp is 4.78%. It's not on the fastest machine in the world (it's a hypver-v guest on a decent machine), but it seems speedy enough. 24gb ram. We've got similar physical hosts running Exchange as a guest without any speed issues whatsoever. Any other info I can provide to help figure this out? Disabling TLS for any gmail inbound mail isn't a feasible option, plus I don't know if it really is just google, or just the way that google connects which others might too... Thank you all. ------------------------------------------------------------------------------ _______________________________________________ Assp-test mailing list Assp-test@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/assp-test
