When a new mail is read, the mail disappears when I move to another mail.
I check "Pegasus New mail", trash, ...
I use Pegasus since 1994, without problems.

I use IMAP

When a new mail is read, the mail disappears when I move to another mail.

IMAP is a protocol that allows Pegasus Mail to display the email on your email providers server. What I picture might be happening is that the provider detects the reading of a message so then either moves it to a different folder or somehow flags it as not being new mail, effectively hiding it from Pegasus Mail. Yahoo had an issue with this back in 2019 (https://support.microsoft.com/en-US/Support/known-issues/email-disappearing-after-being-read-for-imap-configured-accounts ).

Have you connected to your email host via their web interface and searched for any of the messages that you see disappear? This may provide a clue into what could be happening.

Also, if not already done, an internet search for an issue related to disappearing messages, your host, and IMAP might reveal something?
