admin Leave a comment

The Uniform Domain-Name Dispute-Resolution Policy (UDRP) is a process established by the Internet Corporation for Assigned Names and Numbers (ICANN) for the resolution of disputes regarding the registration of internet domain names.

What is Reverse Domain Name Hijacking?

Reverse domain name hijacking refers to a situation where a trademark owner or another party attempts to illegitimately obtain a domain name from its rightful owner through legal means, such as a UDRP (Uniform Domain-Name Dispute-Resolution Policy) proceeding or a lawsuit. This term is used when the party making the claim is found to have acted in bad faith or without a legitimate basis for their claim.

Exim: Rejected by local scanning code

admin Leave a comment

When trying to send emails, if you get “rejected by local scanning code” error:

A message that you sent was rejected by the local scanning code that
checks incoming messages on this system. The following error was given:

Website of user admin is sending too many emails - rate overlimit = 200.2 /
1h

Solution:

Edit /etc/exim4/exim4.conf.template

# Limit per user for PHP scripts
acl_not_smtp:
  deny    message       = Website of user $authenticated_id is sending too many emails - rate overlimit = $sender_rate / $sender_rate_period
  ratelimit             = 200 / 1h / $authenticated_id

  warn    ratelimit     = 100 / 1h / strict / $authenticated_id
  log_message           = Sender rate [limitlog]: log / account / $authenticated_id / $sender_rate / $sender_rate_period

Exim: Message has lines too long for transport

admin Leave a comment

After upgrading to exim 4.95 or exim 4.96, you may receive “Message has lines too long for transport” error after sending email.

Possible Cause: Message content has very long line. Probably HTML.

Possible Solution:

sed -i "s/message_linelength_limit = .*/message_linelength_limit = 2048000/" /etc/exim.conf
systemctl restart exim

or change message_linelength_limit value in /etc/exim.conf

Best Soluton:

Shrink emails’ HTML lines. You can use \n to split long lines. Exim 4.94 had no problem by the way.

This looks like the best and easiest solution.

(The default value of message_linelength_limit is 998)
