Problem on image (only with Cyrillic symbols):

Reason:

1. bug in parsing of the Email content
2. bug in IMAP API: wrong response comes

Fix ideas:

1. Try to use another way of parsing Email content
2. Replace email html_text with plain text and try to parse it

Realize two methods of sending Emails:

1. Telegraph. User creates Telegraph note and provides url with destination Email. We should parse it and create Email with full formatting compliance, with photo attachments. Subject equals title, your name equals last part of Email (farewell), your story equals plain text with formatting.
2. WebApp. Idea is in brainstorming.

1. Add docker-image.
2. Add restarting nats server.

Handle menu button clicks (subscription may be realized later, but click should be handled).

Now the names of the conversion methods are too cumbersome. Fix them.

Translate inline keyboards.

In cases where User removes Bot from Forum, removes Forum, restrict Bot, we should handle them and remove forum from table emails.
This will allow the user to remove the bot from one forum and add it to another, and also reduce the load on fetching Emails with forums from database.

In-need a beautiful algorithm that, with the help of queues and a stack, will provide the first Email fetching and will create topics based on Emails-address-list and n-count last Emails.
In first increment, I'll try to fetch effectively last 30 Email-adresses.

The last sent Email does not fetch in the mailbox. After new (income) Email, penultimate drops.

Create filter or middleware that checks if user subscribed to https://t.me/innerbots Telegram channel.
User can't use bot without subscription for this channel.

We should have a place, where user can create Email-message to some email-destination.

Some Emails, because of race condition between initial fetching and interval fetching, sends more than 1 times.
How to fix: refuse from initial fetcher to checking if the last sent email is None (0). Remove initial fetcher like a concept. This will solve problem with concurrency.

Code-style checkers.
Flake, Black, Pyright.

In-need to limit the ability to connect an infinite number of Emails.
Max Emails count should equals 5.

In all stages of Email-registering pipeline the default menu reply keyboard should be changed to Cancel button and Back button, that cancel process and return to previous stage accordingly.

Rename core packages following hexagonal architecture notation:

Problem on the image:

AppException and ApplicationException duplicate the meaning

Migrate from postgres table with batches and timeouts to nats-server: https://nats.io/.

Fix Email html styles. Make bold subject, Date

1. Build universal Mailbox service built on asynchronously IMAP and SMTP protocols.
2. Integrate Gmail, Yandex, MailRu mailbox services with connection guidelines and unique registering pipelines.
