How to make many connections to mail?

Question

gmail

I have a mail account. There are a lot of connections to it now (about 100). Accordingly, because of this, it is stupid and gmail periodically blocks.
How to get around? Perhaps some kind of mail client will save?

Answer 1

If for some reason you are tied to this mailbox and you only need to work with it, then there are a couple of ideas (crutches)
Make a mail server on a cheap VPS that will solve the following tasks:
Sending: using the login password from Gmail, receive letters from all users of this mailbox and set queue them up, send them strictly according to gmail limits (after all, it’s better if they are sent with a delay than gmail will block you?) How to implement: postfix
Receiving and sorting:
put an imap server on the same server and synchronize via imap with gmail, reconnect all users to it . so all connections will be serviced by your server, and gmail will have only 1 sync connection from your server. What to implement: dovecot + imapsync or equivalents
Z.Y. if you already have 100 clients using one free box, then you are clearly doing something wrong (organizationally) and this is a reason to think.
A rational way out of the situation is to buy / set up your mail hosting with groups and mailing lists, etc., on gmail, set up redirects to the mailing list on your new mail hosting, and answer letters already from the addresses of the new hosting.

Stop trying to use the thing in a mode unusual for it and start your own mail server.
