Garbled emails

[Giray]

I have three vBulletin licenses running on three different urls but on the same server. All are on the same WHM but, obviously, three different cpanels.

For the past couple of days, all emails - sent by users or for confirmations - coming out of any of the vBulletins comes out garbled (text is garbled). Note that only the body of the emails is garbled code, the subject is fine.

All other email functions on the server work fine including POP emails, webmail and mail from our Kayako support desk. Only the vBulletin mails are garbled.

Our hosting company (excellent techs) can't figure it out.

Ideas?
Thanks.

Forgot to mention that we are running a Linux box.

Can you show an example of a "garbled" email ?

Sending from the mail to form in vBulletin, if I type in the word "Hello" in the body, this is what I get:

All my automatic emails (email authentification, etc.) are also garbled.

Remember, this happens from any of my three boards (same server, different urls and cpanels). And the headers (to:, cc: and even subject) are fine.

Hold everything. I just discovered something. Not sure if it helps.
The message arrives garbled in all POP3 clients but not on webmail.

Hmm, I have absolutely no idea what could be causing it. Has your host recently upgraded PHP?

[Giray]

No but the php.ini file was touched. But we can't find anything wrong with it, for now... :ermm:

its base64 encoded?

[Giray]

Yup, that was the problem. Fixed a long time ago, fortunately.
