I have configured sendmail using a procedure described in below : Configure Sendmail to Relay Emails through Gmail SMTP.

https://tecadmin.net/sendmail-to-relay-emails-through-gmail-stmp/.

It works but it takes a loooong time , almost a minute to run and send the mail. Is this something caused by a wrong configuration or any other issue ? Any tip on how to make it faster ? Thank you very much! Any one has experience using zoho mail with digital Ocean ? Thank you!

Some additional info :

  1. Configure Sendmail with SMART_HOST

Now add following configuration lines into your sendmail.mc configuration file below “MAILER” definition.

 define(`SMART_HOST',`[smtp.gmail.com]')dnl
 define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
 define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
 define(`confAUTH_OPTIONS', `A p')dnl
 TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
 define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
 FEATURE(`authinfo',`hash -o /etc/mail/authinfo/smtp-auth.db')dnl

In the next step we will need to re-build sendmail’s configuration. To do that execute:

make -C /etc/mail
  1. Verify Setup

After completing all the above configuration’s, reload the sendmail service to apply changes.

sudo service sendmail reload

Hello,

Have you checked if port 587 is open for outgoing connections?

And what happens if you run:

  1. telnet smtp.gmail.com 587
