You have deployed an email signature containing embedded images. When your email message is received by the recipient and replied to/forwarded from an iOS device, the images in the email signature are removed/displayed as attachments.
This is common behaviour with iOS devices. When you reply to emails that contain embedded images, these images are automatically removed and placeholders are inserted instead. You can see this in the email message when it is composed on an iOS device.
If, however, the iOS user chooses to forward the email, the iOS device will prompt the user to either keep the attachments or remove them. If the user chooses to keep the attachments, the embedded images remain in the message body but are attached to the message separately.
Over a long chain of email replies/forwards all embedded images can be removed and added as attachments.
To resolve this issue:
Instead of using embedded images, host all images on a website or webserver.
By using hosted images it ensures there is no image attachment for the iOS device to remove.
After hosting the image, you can copy the image URL into the dialogue box when inserting an image in your Exclaimer Signature Manager software.
