How to send email via SMTP using MailSo library (PHP) - php

Question

I have a hard time to send multipart MIME message via SMTP using PHP library called MailSo. Provided two examples are limited. No word on how to create headers, message body, multipart MIME message itself and then send it.
Current webmail (Rainloop) is running on MailSo and I want to avoid using 3rd party library on top of MailSo. Going forward all email actions are stored in the Rainloop Actions.php file.
Based on that to create multipart MIME message I should to create $oMessage object (\MailSo\Mime\Message) and I'm able partially do that like to add subject, message ID, custom headers, message body text but going further I'm not able to set MIME boundaries (to store original message body as a boundary as well additional content type as text/plain) not talking about sending $oMessage object via SMTP.
Here is my test code so far:
include 'lib/MailSo/MailSo.php';
echo '<pre>';
$oLogger = \MailSo\Log\Logger::SingletonInstance()
->Add(\MailSo\Log\Drivers\Inline::NewInstance("\r\n", true))
;
$sToEmails = 'Me As Tester <tester#test.com>';
$oToEmails = \MailSo\Mime\EmailCollection::NewInstance($sToEmails);
$sFromEmails = 'Baba Ganush <no-replay#test.com>';
$oFromEmails = \MailSo\Mime\Email::NewInstance($sFromEmails);
$oMessage = \MailSo\Mime\Message::NewInstance();
$oMessage->RegenerateMessageId();
$oMessage->SetXMailer('RainLoop/1.0.0');
$oMessage->SetCustomHeader('test-header','test-header-value');
$oMessage->setSubject("Test message");
$oMessage->AddText('Generated message body goes here...');
$oMessage->SetFrom($oFromEmails);
$oMessage->SetTo($oToEmails);
$oLogger->WriteDump($oMessage);

Well, I have figured out how to send an email message created using MailSo library (w/o any attachments for now)
Example code below
if($oMessage){
$rMessageStream = \MailSo\Base\ResourceRegistry::CreateMemoryResource();
$iMessageStreamSize = \MailSo\Base\Utils::MultipleStreamWriter($oMessage->ToStream(true), array($rMessageStream), 8192, true, true, true);
}
$aToCollection = $oMessage->GetTo();
if ($aToCollection && $oFrom)
{
$sRawBody = #stream_get_contents($rMessageStream);
if (!empty($sRawBody))
{
$sMailTo = trim($aToCollection->ToString(true));
$sMailSubject = trim($oMessage->GetSubject());
$sMailSubject = 0 === strlen($sMailSubject) ? '' : \MailSo\Base\Utils::EncodeUnencodedValue(\MailSo\Base\Enumerations\Encoding::BASE64_SHORT, $sMailSubject);
$sMailHeaders = $sMailBody = '';
list($sMailHeaders, $sMailBody) = explode("\r\n\r\n", $sRawBody, 2);
unset($sRawBody);
$sMailHeaders = \MailSo\Base\Utils::RemoveHeaderFromHeaders($sMailHeaders, array(\MailSo\Mime\Enumerations\Header::TO_,\MailSo\Mime\Enumerations\Header::SUBJECT));
mail($sMailTo, $sMailSubject, $sMailBody, $sMailHeaders);
}
}
