Hi, In amavisd-2.10.0 (and later) is a check is_valid_utf_8() whose regexp makes pcre-6.6 stack overflow when given a To: -header which is more than a thousand rows long. To be exact I stumbled on a To: -header that was a little less than 1400 lines.
Making the stack 10x bigger than default for amavis with ulimit -s 102400 deals with it, but should amavis check the headers line by line rather than in a single blob? BR, Mika -- Mika Ilmaranta <[email protected]> Foobar Linux services +358 50 3023638 Foobar Oy <http://foobar.fi/>
