Zimbra uses Postfix on the back-end, so you should be able to configure it like you would any old Postfix server.

Here's some slightly older documentation for how to connect to remote SMTP servers and send emails using the sendEmail script:
https://www.unixmen.com/send-alerts-nag ... ail-yahoo/

sendEmail has some quirks when connecting to GMail accounts, but I've never had much trouble using it with self-hosted Postfix servers.

Hi,

I am getting below error while sending test mail from coomandline

[root@localhost ~]# sendEmail -o tls=yes -f vmal.parikh@gmail.com -t vimalparikh@zydushospitals.com -s smtp.gmail.com:587 -xu vmal.parikh@gmail.com -xp Z***@*** -u "Hello from sendEmail" -m "how are you? "

Please Help me out.

Did you install the Net::SSLeay and IO::Socket::SSL perl modules on the server like the web site suggested?
If TLS is giving strange errors, try upgrading the Net::SSLeay and IO::Socket::SSL perl modules to the latest version.

Already have latest version installed , Please see the below Output...

There are newer versions available from CPAN so run the following to install the packages from there.

Code: Select all

cpan -i Net::SSLeay
cpan -i IO::Socket::SSL

Try that and see if those versions fix the issue.

Hi Tgriep and Team,

I tried both the command as you said,

yum insatll cpan -i Net::SSLeay
yum install cpan -i IO::Socket::SSL


with -i option it gives error like Command line error: no such option: -i.

and without -i , it gives Error downloading packages:
1:perl-ExtUtils-ParseXS-3.18-3.el7.noarch: [Errno 256] No more mirrors to try.



Please suggest,

Regards,
Vimal

No, you do not add the "yum install" to the commands. Run them exactly like shown, do not add the yum install to them.

Code: Select all

cpan -i Net::SSLeay
cpan -i IO::Socket::SSL
