Save info about filtered mails in the mailbox of account, ... but skip ...
If mails are deleted by any of the mail filters ("Mail Traps" or MailFilt.hst), available information about the deleted mails can be saved in the mailbox of the account given here. This gives the opportunity to review the spamfilter results and become aware of accidentally deleted mails.
As soon as you are sure that the mailfilters work as expected, you can disable this "junk backup" for specific filter results, so the worst spam mails are not saved any more but the more doubtful ones still are. Available options are to turn it off for mails deleted by KILL rules of MailFilt.hst or for DELETE and SCORE rules of the "Mail Traps".
Send summary of filtered mails (spam report) to account
If an account is selected here, it receives a daily "Spam Report" mail, that lists the Subject and From headers of all filtered mails.
Send error and notification mails to account
Name of account to receive error and other notification mails (default: admin).
If marked, a unique Message-ID is added to new mails sent to Hamster's local mailserver (SMTP
server), if they were sent without one (i. e. existing Message-IDs will not be replaced).
The local-part of the Message-ID consists of coded values for current time, task-number and a
counter per time. The domain-part is the configured FQDN.
If marked, Hamster's "User-Agent:" header is added to new mails.
If marked, a "Received:" header is added to new mails.
Req. Authentication ... SMTP-after-POP3
If marked, local SMTP can only be used after successful authentication.
This setting also enables, that a previous login on local POP3 server from the same IP also grants
access to the local SMTP server for a given amount of time.
Req. Authentication ... Duration
Period in seconds, for which a POP3 authentication remains valid for SMTP-after-POP3 authentication (see above).
Req. Authentication ... SMTP AUTH
If marked, local SMTP can only be used after successful authentication.
This setting also enables using SMTP's AUTH command for authentication.
Accept mails for local recipients without prior authentication
If marked, local SMTP server accepts mails for local users without prior authentication. Remote recipients will still be rejected in this case if authentication is required by the settings above.
Reject mails that do not pass all Mail Traps
If marked, the Mail Traps defined for fetching
mails will also be checked for mails sent to local SMTP server and offending
mails will be rejected immediately.
Please note, that for privacy reasons, the additional backup and spam report
options for Mail Traps on page Local Mail do
not work in this case, only matching rules are logged.
If the domain-part of a mail-recipient (the text following the "@"-character) matches the regular expression given here, the mail is not send out but delivered locally.
The default-setting is:
.*hamster|\[?127\.0\.0\.1\]?|.*invalid
Examples for "local" addresses covered by this setting:
.*hamster someone@something.hamster
\[?127\.0\.0\.1\]? someone@127.0.0.1, someone@[127.0.0.1]
.*invalid someone@nospam.invalid
Note: Addresses without a domain-part or domains without at least one dot (".") in it are always assumed to be local-only, regardless of this setting.
