.net - "Quoted-printable line longer than 76 chars" warning when sending HTML E-Mail -


i have written code in vb.net application send html e-mail (in case, lost password reminder).

when test e-mail, gets eaten spam filter. 1 of things it's scoring badly on because of following problem:

mime_qp_long_line  raw: quoted-printable line longer 76 chars

i've been through source of e-mail, , i've broken each line longer 76 characters 2 lines cr+lf in between, hasn't fixed problem.

can point me in right direction?

thanks!

quoted printable expands 8 bit characters "={hex-code}", making messages longer. maybe hitting limit?

have tried break message at, say, 70 characters? should provide space couple of characters per line.

or encode email base64 - mail client can handle that.

or set content-transfer-encoding 8bit , send data unencoded. know of no mail server unable handle 8bit bytes these days.
