PavshinSergei In some cases in Sogo (the cases that I could record myself were sent from iPhone devices) attachments to the letter are not displayed. At the same time, in RoundCube the attachment to the letter is displayed in the standard way
esackbauer Same here. Seems to happen when an iOS user sends a mail with embedded image. My users are using SMTP (not ActiveSync) This error was introduced with 5.12 of SOGo. Strange that such an obvious error is not yet tracked on https://bugs.sogo.nu/ So I would suspect that could also be an issue on mailcows nginx.
PavshinSergei I don’t think the problem is in Nginx. After all, on the same mail server, but with a different interface (RoundCube), everything is displayed normally
esackbauer PavshinSergei different interface, different code, which may or may not affect nginx rules.
