Fighting spam in phone database

As I already complained, spammers seem to like my phone database. It has not been a major problem so far, but I started to get about ten invalid records per day.

This forced be to find automatic solution to get rid of this. Inspired by recent article on root.cz, I wrote simmilar solution as is used on php.vrana.cz. It should not harm regullar users who have javascript enabled, others will have to fill in one extra field.

  • Fix adding part to SMS after removing all.
  • Fix editor on Windows.
  • Now requires wxWidgets 2.6.

Blacklists consireder harmful

After my mailserver started to reject mails from servers where I want to accept mails, I decided to finally try to disable DNS blacklisting. Earlier I whitelisted some domains, but the list has grown too much.

I still use DNS blacklists as helping criterias for SpamAssasin, but being on blacklist is now not enough to reject legitimate mail. Let's see if spam amount in my mailbox will increase, but I doubt it will, other checks are also quite restrictive.

Spam in phone database

During regullar review of additions to phone database, I noticed that some people tried to add spam and links to their sites. I'm not going to add any further restrictions on database, but to make spammers life a bit harder, I added logging of IP addresses which I'm going to block if they attempt to add some links.

Fortuntely spam volume is htere low enogh to be still handled manualy.

Developer documentation

I started to collect developer information on wiki. Please add there any hints that might be useful for people who are interested in contributing to phpMyAdmin.

While working with documentation, I used phpDocumentator to generate our API documentation, you can see it on my website.

What am I doing wrong?

What the hell am I doing wrong that I can not send mail to any @debian.org address?

SMTP error from remote mail server after end of data:
host master.debian.org [70.103.162.30]: 550 Administrative prohibition

None of SMTP servers I used is blacklisted and I haven't seen problem with any other recipient than master.debian.org. Anyway it would be great if I would know what this Administrative prohibition means. After googling I found out that it might be something bad in my headers, but nothing what would tell me how to fix it...
