Searched for solutions on these forums and found some similar issues, but the file contents must have changed between osTicket versions and it was hard to find the right location to apply fixes.

One suggested solution which helped: (by zkenstein).

My solution based on the above post:

Open include/class.mailer.php

Line 138, replace:

$mime = new Mail_mime();

with:

$crlf = "\n";

$mime = new Mail_mime($crlf);

Other workarounds suggest using SMTP instead of the default PHP mail function, which appears to successfully bypass the issue, but this wasn't an option for my setup.

osTicket doesn't use phpMail, it uses PEAR's Mail and Mail_SMTP. Did you customize your osTicket install?

PS - Actually, I feel like a noob here -- I can't find a phpMail project. Maybe we're talking about the same thing

You might also try changing line 153 (or so) in include/class.mailer.php from/to

'text_encoding' => 'quoted-printable',

'text_encoding' => 'base64',

I'm using the default setup. /shrug, it's been a while since I've used PHP etc. What I was meaning is internal email (PHP based) as opposed to an external SMTP server.

I'll edit the OP.

Just reversed my change and tried that out, works perfectly as well. Less code to change makes it simpler.

From what I just read, base64 shouldn't really be an issue with today's email clients and servers. We're using osTicket internally so it's fine as it did work as expected.

Thank you, Jared.
