Summary0001344: Sieve filter 'reject' generates incorrect script on single-line messages
Description

If you create a sieve filter with a 'reject' action, and the message accompanying the reject is a single line, then incorrect sieve is generated. The offending line is of the form:

 reject text: "Single line message";

The Dovecot ManageSieve rejects this - "invalid character after 'text:' in multiline string - and drops the filter file. So all your filters mysteriously don't work.

Additional Information

From a quick reading of RFC5228, it looks to me like generally single line text is simply quoted. Multi-line text starts with 'text:'. So the above should be:

reject "Single line message";

or

reject text:

A message with
more than one line.
.
;

In SOGoSieveConverter.m, asSieveQuotedString() checks the input string for newlines and generates single-line format if none, or multi-line format if any are present. In the latter case it does not add the 'text:' prefix. In the case of 'reject' this is always prepended to the result of asSieveQuotedString(). Hence if the reject message is a single line, 'text:' is present incorrectly.

I assume that there is scope for the reverse problem to occur elsewhere - multi-line text being returned to other commands expecting a single line quoted string.

I think what should happen is that 'text:' should be prepended to multi-line values returned from asSieveQuotedString(). Something like the attached (untested, and I'm Objective C ignorant) patch.

I have now tried the attached patch 'reject2' and confirmed that it does fix the problem. Single line and multi-line reject messages generate correct Sieve, and 'redirect', the only other free-text argument Sieve action available from the web still works too. Please consider applying.

(I don't seem to be able to delete an attachment I uploaded. Is this expected?)
