I'm trying to set up cygwin /usr/bin/email to send the output of various
cron jobs to email.
I previously had this set up and working on Windows 10, and with another
hosting provider (WHM/Cpanel on CentOS with exim). Now I am running
Windows 11 (24H2), with a fresh Cygwin install CYGWIN_NT-10.0-26100
3.5.5-1.x86_64. The SMTP server is with a new hosting provider -
InMotion Hosting, a vps running AlmaLinux v8.10.0 STANDARD virtuozzo
cpanel/whm 124.0.21 with exim email server.
I'm getting a timeout connecting to the smtp server using a test
command-line call to /usr/bin/email (names have been changed to protect
the guilty):
[snip]
USE_TLS = 'true'
SMTP_AUTH = 'LOGIN'
SMTP_AUTH_USER = 'myu...@mydomain.com'
SMTP_AUTH_PASS = 'mypassword'
I've also tried using port 465, get
Init connection...
email: FATAL: Smtp error: Timeout(10) while trying to read from SMTP server
The notes on /usr/bin/email mention the TLS is somewhat primitive, I'm
wondering if there's an issue with connecting to the later version of
exim? Or maybe I'm missing - or messing - something in the
configuration either cygwin or server side?
Perhaps this is relevant (from Microsoft):
"Starting in Windows 11 Insider Preview builds for September 2023 and
continuing in future Windows OS releases, TLS 1.0 and 1.1 will be
disabled by default. This change increases the security posture of
Windows customers and encourages modern protocol adoption. For
organizations that need to use these versions, there's an option to
re-enable TLS 1.0 or TLS 1.1. For more information, see Resources for
deprecated features."
and:
"If there are no alternatives available and TLS 1.0 or TLS 1.1 is
needed, the protocol versions can be re-enabled with a system registry
setting. To override a system default and set a (D)TLS or SSL protocol
version to the Enabled state:
...
TLS 1.1:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
1.1\Client]
"Enabled" = dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
1.1\Server]
"Enabled" = dword:00000001
... (disclaimer)
"
The other option is to change eMail to use a newer version (I vaguely
recall helping with this on the git issues page, but I might be
mistaken. It was a trivial change in the code, can't remember if it was
accepted and its already there with version:
$ email --version
email - By Dean Jones; Version 3.2.3-git
Anyway it is in my local install (I build it myself before it was a
Cygwin package), and I'm pretty sure it doesn't work anymore, so more
code changes are needed.
Hope this helps!
