Hi. I receive a lot of spam messages every day. From different jabber servers. There are legit, like jabber.cz and not legit/not used, like bashtel.ru
I want to lock all this spam servers like bashtel.ru in iptables. A want to do it in iptables, not in config files.
How I can do it? How to write iptables rules correctly?
Looking for ejabberd docs?

This is a good question, than many linux administrator tutorials and websites can solve, if you search for it, right?
By the way, I see that ejabberd 17.03-beta will include a new module called mod_block_strangers. Once released, take a look, maybe it also helps to fight spam.
I try: iptables -A FORWARD -m
I try:
iptables -A FORWARD -m string --string "bashtel.ru" --algo kmp --to 65535 -j DROP
I'm I right?
wow. it's good news, because this spam ennoying every day, not only outgoing, also incoming
Don't work such rule iptables
Don't work such rule
iptables -A FORWARD -m string --string "bashtel.ru" --algo kmp --to 65535 -j DROP
Where is the mistake?
