Filter Rules not applying to sent e-mails

Samuel R. Messner shared this problem ago

Published

I have a number of custom e-mail addresses aliased to my Mailbox.org account, and I use Filter Rules to tag each e-mail with the e-mail address it's tied to (for, for example, filtering purposes). However, I've noticed an issue: Sent e-mails aren't processed by Filter Rules! For example, given the following Filter Rule…

89730cff0178a83c70afc4b238095129

…if I send an e-mail from example@mydomain.me, it isn't tagged accordingly with that IMAP keyword. It may be undesirable for some users to have their filters apply to sent e-mails – especially filters that, for example, move e-mails to another folder – could perhaps a checkbox along the lines of “Apply to sent e-mails” be implemented?

I think i have sort of the same issue?

My alias emailadresses are sorted in my inbox through a rule so they end up in the desired folder under de INBOX folder. I would like to have this behaviour also for the sent emails. But this doesn't seem to work, only when i apply the rules to the folder, all emails in the SENT inbox are sorted to the right folder. So it looks like the rule isn't live but only works once untill reapplied.

Can anybody confirm this behaviour, so i can stop trying all the different rule options? Or is there already a working workflow for this? If so, i would be gratefull to know how to get this working properly.

This is how SIEVE works!

"The reason is that Sieve filters only apply to mail that is delivered “normally” to your mailbox address via SMTP."

Use a smarter MUA.

Thanks zapata for your quick reply!

I'm not using a external mailclient, so you say that my setup for my SENT INBOX isn't possible through mailbox.org? But what would be the difference when using a smarter MUA, the basic setup comes from mailbox.org. So because a sent email is not delivered through SMTP like a normal incoming email it will not be filtered the same way, is this correct?

If only that filter on the SENT INBOX could become a live filter…

In a MUA like Thunderbird you can create identities where you can define a Sent Folder (local or on the remote IMAP Server).
