Corrupt PDF

Problem reported by Eric Tykwinski - 8/28/2018 at 10:52 AM

Running SmarterMail Enterprise Version 15.7.6782

So I'm expecting this is a combination issue.

PDF attachment sent from Outlook comes in as

Content-Type: application/pdf; name ="xxx.pdf"
Content-Transfer-Encoding: quoted-printable

Mime markers look good on sent items in webmail:

------=_NextPart_000_014C_01D43ECD.50E8D140

------=_NextPart_000_014C_01D43ECD.50E8D140--

On recieving end Mime markers are corrupted:

------=_NextPart_000_0146_01D43ECD.50231040

~{------=_Ne~}?~{Part_000_0146_01D43ECD.50231040-~}?

Tested to Postfix and an Exchange server to verify recieving end isn't a problem.

SmarterMail's webmail works fine sending, and send the attachment in base64.

Tested the same email from Postfix to SmarterMail and it comes in fine as quoted-printable.

My guess is the specific PDF, which I don't think I can share, but has anyone else noticed this...

Perhaps a hotfix in the works?

Just a side note if someone else is searching for a fix:
This was fixed with Version 15.7.6821 (Sep 4, 2018)
IMPORTANT: Fixed issue where TCP connections are being prematurely closed under certain circumstances, causing a variety of issues.
