This is more about gmail ?spam protection?. Gmail filters emails after accepting
them with secret criteria and sometimes the email ends up in spam folder and
sometime it is just silently deleted.

By using gmail there is no way of telling how many (important) emails you have
not received because of this.

While Gmail's spam classifcation is frustratingly opaque (as with many
other providers), there's one other weirdness that can make messages
dissappear: when you send from Gmail through a forwarder back to the
same Gmail account.

The mail will be accepted, but not appear in your INBOX.  This is either
some labelling weirdness (cannot be labelled as both INBOX and Sent) or
maybe an anti-loop protection.  This causes confusion when Gmail users
test their mail forwarding I set up for them.

However, we're truly off-topic: my point was that Gmail users get a
distorted sense of how most mail systems work (mailbox operations scale
with message count), as they get brainwashed into the "Gmail" way of
doing things.  A relevant question is whether you can use Dovecot's
virtual mailbox feature to define a catch-all virtual mailbox to placate
these users which won't bring an imap process to its knees.

For me, it is not because of Gmail spam filters. I confirm I had the
emails in my inbox previously, and then sometime later the emails were
deleted mysteriously. Not sure who deleted my emails. Definitely not
because of Gmail spam filters.
