I'm also wondering if there are multiple issues. I have one way of easily reproducing, but it has nothing to do with IMAP IDLE. Here's a test email which causes the hang - snipped it a bit in the middle which you can fill out yourself with: dd if=/dev/urandom bs=1024 count=3432 | base64 -w76 If you want to test multiple times, change Message-Id for every delivery. This mail can be simply saved to INBOX, e.g. with doveadm save: To: <u...@example.com> Subject: testing Content-Type: multipart/mixed; boundary="foo" Date: Tue, 17 Dec 2024 06:46:17 +0000 From: <u...@example.com> Message-Id: <fo...@example.com> --foo Content-Type: multipart/alternative; boundary="bar" --bar Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=UTF-8 asdf --bar-- --foo Content-Description: test.pdf Content-Disposition: attachment; filename="test.pdf" Content-Transfer-Encoding: base64 Content-Type: application/octet-stream; name="test.pdf" lBjZO0luFuyUiOqQ8KPTTpMyPoNhlSTPPJauDuCVSwbZgaNyhnObul5qrdyPKo0NGiQKA3Kha34A <61642 lines of random> 4cNyk39T2wMsnQavfl8LXwG1vNQylpgmSN4p6fOpmGqQ --foo-- _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org
