Hello,

Are the domains which you're sending the attachment to located on your server or are they remote domains? If the attachment is being stripped or the mail is failing to send with the attachment, then it's likely that the remote host has blocked attachments or specifically pdf files as attachments

Yes.. from email as our website domain.. but gmx.de, gmx.com not receiving.. I used SMTP details as of my website associated

How long are the pdf file names.
I've seen similar issues where the file name is extremely long with underscores.

Also, if the pdf was converted from a doc file, and has a double dot file extension.

eg: mypdffile_this_is_the_one.doc.pdf

This will trigger our firewall, and end up being stipped out.

Just 8 charater alphanumeric ex: ye34mncj.pdf , even one page pdf information, but i can send this pdf manually from my gmail account to that users it will get delivered

It's quite possible that when sending this as a result of a script it is causing it to be flagged as spam, unfortunately, without any details on this, we wouldn't have a way to know which. When testing, is the email sent with the attachment successfully to other addresses?

All other address got sent perfect..

Hello,

Do any of the attempts get sent in the same way, with the same titled PDF and to the same location?
