Description
Using SMTP protocol to transfer emails ensures solid operations.
It is very easy to set up SMTP. You can find the settings for this plugin at the bottom of WordPress admin menu Options / General.
You should get your SMTP settings from your ISP, hosting provider, webmaster, email provider etc.
Using every option SMTP URI formally looks like this:
smtpTLS://USERNAME:PASSWORD@HOST:PORT
Thus encryption type and ://
and user name and :
and password and @
and mail server name and :
and port number.
All except encryption type and mail server (host name) are optional.
SMTP encryption types are as follows:
- For encrypted connection (STARTTLS on submission port) start your SMTP URI with
smtpTLS://
– the default port is 587. - For fully SSL encrypted connection (SMTPS) start it with
smtps://
– the default port is 465. - For unencrypted connection (plain SMTP) start it with
smtp://
– the default port is 25. This is not recommended for non-local servers.
WARNING! Use URL-encoded strings.
You can find the settings for this plugin at the bottom of WordPress admin Options / General.
You may define your SMTP URI also in wp-config.php
:
define( 'SMTP_URI', 'smtpTLS://USERNAME:PASSWORD@HOST:PORT' );
To set From:
name and From:
address use
WP Mail From II plugin.

.

.
