Bug description:
  Very recently, my (unchanged for years) bionic exim4 flow ( outgoing
  SMTP -> smtp.canonical.com ) abruptly stopped working, with exim4 log
  as follows:

    SMTP<< 220 smtp-relay-canonical-1.canonical.com ESMTP Postfix (Ubuntu)
    SMTP>> EHLO myhostname
    SMTP<< 250-smtp-relay-canonical-1.canonical.com
           250-PIPELINING
           250-SIZE 61440000
           250-VRFY
           250-ETRN
           250-STARTTLS
           250-ENHANCEDSTATUSCODES
           250-8BITMIME
           250-DSN
           250-SMTPUTF8
           250 CHUNKING
    SMTP>> STARTTLS
    SMTP<< 220 2.0.0 Ready to start TLS
    SMTP>> EHLO myhostname
    H=smtp.canonical.com [185.125.188.121] TLS error on connection (recv): Resource temporarily unavailable, try again.
    SMTP(close)>>
    H=smtp.canonical.com [185.125.188.121]: Remote host closed connection in response to EHLO myhostname

  This appears to be a manifestation of this exim4 bug which was fixed in exim4 (4.92): https://bugs.exim.org/show_bug.cgi?id=2359
  See also: https://www.mail-archive.com/exim-users@xxxxxxxx/msg53121.html

  I found and installed a PPA version of exim4 (4.94) for bionic, which
  did fix the problem for me.

  I believe that all Ubuntu versions which supply exim4 < 4.92 {Bionic,
  Xenial, Trusty} are affected by this bug, which leaves exim4
  mysteriously broken when the server side happens to move to TLS 1.3.

  I suggest updating exim4 on the affected Ubuntu versions.
