Inserting: $body=""; at line 2924 seems to solve the problem.

Fri, 15 Apr 2022 10:12:08 +0000 https://bugs.horde.org/ticket/15103#t94008 I can confirm the bug, on IMP 6.2.27, attachment as a link when exceed max size works when mail is plain text but not when it's html. Adding the line $body=""; seems resolving the problem Thu, 04 Jul 2024 14:48:24 +0000 https://bugs.horde.org/ticket/15103#t94204
