IIS6 Virtual STMP server and iPhones

Question

User1180295777 posted

Hello, I have inherited and IIS6  running a Virtual STMP server from which our App relays emails through.

 

Some iPhone users have commented that the HTML emails they should be receiving are coming thought as "quoted-printable".

I cannot see what I need to change to stop this.

There is only customer using the app that has commneted on having the problem, and it's not all iPhone user (some of them receive the email fine).

Android, windows, and MAC users seem fine also.

I've checked the email headers, and, it's going through office 365 mail protection. I can also NOT see 

Content-Transfer-Encoding: quoted-printable

I am at a loss as to why some would work, and others not.

has anyone else experienced the same issue, and care to share their <g class="gr_ gr_473 gr-alert gr_gramm gr_inline_cards gr_run_anim Style multiReplace" id="473" data-gr-id="473">solution ?</g>

Thanks

Hi G-oker,

For workaround try to put Content-transfer-encoding  as you want for IOS  in header file and see the result. also check your codding that any code is affecting this issue.

Check below article about  Content-Transfer-Encoding Header Field:

https://www.w3.org/Protocols/rfc1341/5_Content-Transfer-Encoding.html
