Mail::...::Utils(3)

💖 NAME 💖

Mail::MIMEDefang::Utils — bestie, these are the support methods that do the behind-the-scenes heavy lifting. They get called internally, and your email filters can call them too. 🫶

---

✨ DESCRIPTION ✨

Mail::MIMEDefang::Utils is literally a whole little squad of methods. You can call them from mimedefang-filter, or they can be called by other methods. Either way, they're here, they're iconic, and they're doing the work. 💅

🎀 METHODS 🎀

• time_str — returns a string that represents the current time. That's it, that's the whole vibe. ⏰
• hour_str — returns a string representing the current hour. Just the hour, main character energy only. 🕐
• synthesize_received_header — synthesizes a valid Received: header to reflect re-mailing. This one is needed by Apache SpamAssassin so it can correctly parse email messages. No cap, SpamAssassin needs it. 📨
• copy_or_link — copies a file if it fails to create a hard link to the original file. Plan A flops, plan B slays. 🔗
• read_results — extracts an array of command, key, values from the RESULTS file. Needed for regression tests. 🧪
• re_match — returns 1 if either Content-Disposition.filename or Content-Type.name matches the regexp; returns 0 otherwise. 🔍
• re_match_ext — returns 1 if the EXTENSION part of either Content-Disposition.filename or Content-Type.name matches the regexp; returns 0 otherwise. Only the extension part, bestie. 🌸
• re_match_in_rar_directory — returns 1 if the EXTENSION part of any file in the rar archive matches the regexp. To enable the check, $Features{'unrar'} should be enabled. 🗜️
• re_match_in_7zip_directory — returns 1 if the EXTENSION part of any file in the 7zip archive matches the regexp. To enable the check, $Features{'7zip'} should be enabled. 🗜️
• re_match_in_tgz_directory — returns 1 if the EXTENSION part of any file in the tgz archive matches the regexp. Files with extensions .tar.gz, .tar.bz2 and .tbz are also checked. To enable the check, $Features{'tar'} should be enabled. 🗜️
• re_match_in_zip_directory — returns 1 if the EXTENSION part of any file in the zip archive matches the regexp. 🗜️
• md_copy_orig_msg_to_work_dir_as_mbox_file — copies the original INPUTMSG file into the work directory for virus-scanning, as a valid mbox file. 🦠
• gen_mx_id — generates a random identifier that MIMEDefang uses to create temporary files. 🎲
