Re: alias group and limit

[natan]

Hi

This is incomming e-mail. External user send one e-mail to alias group like "a...@domain.ltd"

a...@domail.ltd after roll is ~300 e-mail

trace is like:

mail a...@domain.ltd go to my MX ---go-to-amavis-sa------>postfix----rollbac-alias-group-to-300-users----lmtp-dovevot

and is any chance to limit that ?

do you want stop them from sending mail to over 100 recipients?
you can configure smtpd_recipient_limit for client connections.
Note that they may send multiple mails.
