Hello, Exim Version 4.89 (Debian Jessie)
When sending mails to (primarily) outlook.com or Hotmail about 0.1% (1 in 1000) results in something like this: --- 2017-07-26 08:12:33 1da6x5-0005fV-IX H=redacted.mail.protection.outlook.com [23.103.139.138] TLS error on connection (gnutls_handshake): timed out --- And more importantly in a massive delay like this: --- 2017-07-26 08:12:33 1da6x5-0005fV-IX TLS session failure: delivering unencrypted to redacted.mail.protection.outlook.com [23.103.139.138] (not in hosts_require_tls) 2017-07-26 08:12:35 1da6x5-0005fV-IX Completed QT=2h11m24s --- This is clearly something like a bad host within their load balanced pool, since a mail with multiple recipients might get delivered to a few and then hit this issue. As is is not exclusively happening with these M$ domains I'm more interested in a generic solution, read, can the gnutls handshake timeout be configured to be something more sensible (like a minute or less)?
