If mime mails are sent out I get error messages from some mail servers:

SMTP error from remote mail server after end of data:
host XXXXXX.de [XXX.XXX.XXX.XXX]: 500 5.6.1 Line too long.

In the source of the email I can find one line with the CSS style definitions which has nearly 25000 characters. Some of the mail servers seem to be unable to handle this.

Hi,

i can confirm this problem. The biggest german ISP (T-Online) doesn't except these mime mails (with same error code).

Yes, I have the same problem. My users don't receive their notification mails. User 1 only gets this error message.
Does anybody know what the problem is and how it can be solved?
