How to import translated strings having dynamic variables?

Question

Short: How can I import .po file having dynamic variables in strings like follows

$message = t('Hi @firstname, please follow @sitelink or mail me at @email ', $var);

Indetail:

I've written a custom module to send mail notification to users. In that module $message string has dynamic variables like follows (sample)

$var = array('@firstname' => $username, '@sitelink' => $GLOBALS['base_url'], @email => $email);  
$message = t('Hi @firstname, please follow @sitelink or mail me at @email ', $var);

How can I import $message string to my site.

I could translate all the static strings to Spanish of other custom modules like follows.

#: mycustom.module
msgid "Are you sure to approve"
msgstr "¿estás seguro de aprobar"

But how can I write the same for Dynamic variables. Right now Spanish Users are getting their mail in English?

Note: I'm just using Drupal core Locale module.

There are two way to achieve this

Add string in a your .po file like follows

msgid "Hi @firstname, please follow @sitelink or mail me at @email"
msgstr "Hola @firstname, por favor, siga @sitelink o envía un email al @email"

and import that .po file by going

Administration » Configuration » Regional and language » Translate interface » Import

If you want to change individual translated strings go to

Home » Administration » Configuration » Regional and language » Translate interface » Translate

You can find list of strings there each having edit link beside. So you change the individuals like follows.

Hope this helps someone.
