[horde] horde-alarm and a simple smtp server

[A. Schulze]

Hello,

the cron running horde-alarms complain:

----
Schwerer Fehler:
Server does not support 8-bit message data.
In /usr/share/php/Horde/Smtp.php in Zeile 588

Yes, the SMTP server do not announce 8BITMIME smtp extension.
Looks like that hurt horde-alarm but not IMP...

As far as I know there is no option "$conf[smtp_uses_7bit_only]", right?
But that's exactly what I miss in Horde (and other MUA, too)

Why did I disable 8BITMIME?

Suggestions?
