I am on Mac OS 10.10.5 (Yosemite).
Recently I started to have problem that I cannot attach a file to the email. If it is longer than 80K - 100K then a failure.
Local client like mail.app or thunderbird just refuse to send such email with attachment, with the message that connection was lost.
I tried web client - Gmail. The same story, 100K attachment fails to download to be attached to email.
After reboot of this Mac 1 I was able to send email with 100K attached file, but only once after that it would fail again.
Now, I have another Mac (the same version), which I rarely use (it runs 24/7 for backups and as a fileserver). That Mac does not have such problem.
The only thing I can think of is that I installed something on Mac 1 and it corrupted something (https, tcp libraries).
Any ideas are welcome.
