Maildev behind apache virtual directory fails to load CID:Images

[balajeeoshift]

The email content in the EML file is

`<td valign=3D"top" height=3D"52" width=3D"600" style=3D"padding:0px 24px 0px 24px;"><div style=3D"text-align:left;"><a href=3D"https://domain.com?utm_source=xxxxx" style=3D"text-decoration:none;"><span styl=
e=3D"height:51"><img src=3D"cid:448997419133796281@E.G" alt=3D"" width=3D"140" height=3D"51" border=3D"0" style=3D"display:block;margin-left:0;margin-right:auto;">

`

HTML content on the Maildev application is

<img src="//testdomain.com/email/J0t6L7Mh/attachment/logo.png" alt="" width="140" height="51" border="0" style="display:block;margin-left:0;margin-right:auto;">

I have the following apache virtual directory config for mail dev
<Location /smtpdev/>
RequestHeader set X-Request-URL "https://testdomain.com/smtpdev/"
RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port 443
ProxyPreserveHost On
ProxyPass "http://127.0.0.1:2580/"
ProxyPassReverse "http://127.0.0.1:2580/"

Version : MailDev 2.0.5
