Fri, 10 Apr 2026 02:41:22 +0000 https://bugs.horde.org/ticket/9099 HTML multipart/alternative should be a pref or mime_driver conf This is a delicated issue, but I think this is very important for IMP.. I will try to explain using my terrible english (lol).. The IMP uses by default multipart/alternative for images and this creates a "trouble" in networks where the server can't access internet (outgoing port 80) ... Now I'm working at a company where we have this problem, the webserver can't access internet... Analyzing the code of IMP and trying to find a solution I've identified the following item: "./imp/lib/Compose.php" Line 1081 if (empty($options['nofinal'])) { /* Any image links will be downloaded and appended to the * message body. */ $textpart->addPart($this->_convertToMultipartRelated($htmlBody)); } else { $textpart->addPart($htmlBody); } As my server can't access internet and don't have a proxy server, IMP always returns "connect timed out!" when try to get images and doesn't send the message. I propose that this be done by conf file, for example: if ($conf['compose']['usemultipart']) { /* Any image links will be downloaded and appended to the * message body. */ $textpart->addPart($this->_convertToMultipartRelated($htmlBody)); } else { $textpart->addPart($htmlBody); } Sorry if this already exists in IMP, I couldn't find and I'm sure that it is a good discussion.

Added config option to IMP 5. Also, if error occurs during the download of data, fallback to sending the message with links only.
