Hi Alexander,

Stupid question: does filtering to an alternative root folder work when you leave all the unicode/emoji stuff out? Maybe you misconfigured something else for delivering to mailboxes that are not under INBOX?

Can you do a simple 'fileinto: "test";' and start debugging from there?

Kind regards,

Tom

Hello again

I really, **REALLY** do not get the issues with filtering _AT ALL_.

For testing, I now added such a rule:

if allof (address :regex :comparator "i;octet" "from" "@(bluewin\\.ch|yahoo\\.com)$") { addflag "$label3"; fileinto "INBOX/🎗 Social Networks"; stop; }

When I send an e-mail from either my "bluewin.ch" or "yahoo.cm" account, it gets flagged with "$label3" and filed to "INBOX/🎗 Social Networks". Just like it should be - all good :)

BUT…

When I change that "fileinto "INBOX/🎗 Social Networks";" to "fileinto "🎗 Social Networks";", I'll get errors like that:

error: msgid=<1498541093.5055416.1744698567525@email.bluewin.ch>: fileinto action: failed to store into mailbox '🎗 Social Networks': Mailbox doesn't exist: 🎗 Social Networks.

The mailbox "🎗 Social Networks" *does* exist - it's a "main folder", so to say; NOT under "INBOX".

...

Why is that so? How could that be debugged properly?

Regards,

Alexander

Hello

I've got issues using filters. Although a filter matches a message, the message remains in the INBOX. In the log file a@skwar.xyz.sieve.log, I find this:

sieve: info: started log at 2025-04-14 18:15:31 +0200. error: msgid=<1051036477.1870592.1744647326637@mail.yahoo.com>: fileinto action: failed to store into mailbox '🎗 Social Networks/🏔🚴 Draussen': Mailbox doesn't exist: 🎗 Social Networks/🏔🚴 Draussen.

Yes, the folders are **really** named "🎗 Social Networks" and "🏔🚴 Draussen" 😜 I like emojis, makes it easier for me to find things again 🙂

The filter rule for this is:

require ["regex","imap4flags","fileinto"]; if anyof (address :regex :comparator "i;octet" "from" ".*@(yahoo\\.com|bergportal\\.ch|freezetag\\.com|garmin\\.com|geocaching\\.com|komoot\\.de|munzee\\.com|quaeldich\\.de|spontacts\\.com|squadrats\\.com|strava\\.com|update\\.strava\\.com|velocity\\.ch|wandrer\\.earth)$", address :regex :comparator "i;octet" ["to", "cc"] "hiking-buddies@acc\\.alexs77\\.rodeo|carving\\.fleshed313@alexs77\\.foobar\\.vip|com\\+wandrer\\.earth@skwar\\.me|squadrats\\.com@acc\\.alexs77\\.rodeo", address :regex :comparator "i;octet" "from" "hikingbuddiesteam@gmail.com|email.meetup.com") { fileinto "🎗 Social Networks/🏔🚴 Draussen"; stop; }

In this case, it matches on "<whatever>@yahoo.com".

Why did it not find the folder?

I created the folder and rule in SOGo 5.12.0 from mailcow 2025-03b.

bd36093fccaa:/var/vmail/sieve# dovecot --version 2.3.21.1 (d492236fa0)

Should the Emojis somehow be encoded, so that the filter would work?

Cheers, Alexander

You should begin by posting your configuration (dovecot -n)

It's a bit much, I would've thought. But, sure.

The issue is, that some filters work, while some others do not.

Filter:

if anyof (address :contains ["to","cc"] "cassandra@skwar.me", address :contains ["to","cc"] "cassy@skwar.me", address :contains ["to","cc"] "c@skwar.me") { addflag "$label7"; addflag "\\Seen"; fileinto "INBOX/🫥 Privat/🦸🏼‍♀ Cassandra"; stop; }

The folders exist.

I've got this additional filter:

if anyof (address :regex :comparator "i;octet" "from" "@(swisscom\\.com|skwar\\.me|5y5\\.one)$", address :contains "from" "alexander-s@bluewin.ch") { addflag "$label3"; fileinto "INBOX/🫥 Privat"; }

It works fine — an email from alexander-s@bluewin.ch was filed into "INBOX/🫥 Privat".

/var/vmail/sieve/a@skwar.xyz.sieve.log contains:

sieve: info: started log at 2025-04-22 21:34:53 +0200. error: msgid=<890352f2-9eab-4574-a871-a56e19d47ee0@facebookmail.com>: fileinto action: failed to store into mailbox 'INBOX/🫥 Privat/🦸🏼‍♀ Cassandra': Mailbox doesn't exist: INBOX/🫥 Privat/🦸🏼‍♀ Cassandra.

Hm, I do not see how I could set this up in SOGo or Roundcube. I am not creating the rules by hand but use these webmail systems.
