if we charge drinks for every such occasion, we will easily become alcoholics.

It is oh so quiet....

by Jeroen Massar

As it is kinda quiet, let me break that stillness with the oh so important question: Who can provide native IPv6? :) That is of course for these two lists: http://www.sixxs.net/faq/connectivity/?faq=native http://www.sixxs.net/faq/connectivity/?faq=ipv6transit Replies offlist are great, flamewars on the list are cool too <grin> Greets, Jeroen

Re: [swinog] RBL's (again) (Was: Anyone from Green here?)

by Stanislav Sinyagin

actually about a year and a half ago there was a new spambot which was re-sending the message after a temporary reject. But it did it precisely in 4 minutes after the first rejection, and never tried again. So, increasing the greylisting timeout to 5 minutes has solved the problem :) ----- Original Message ---- > From: Adrian Senn <adrian(a)senn.ch> > To: swinog(a)swinog.ch > Sent: Thursday, September 11, 2008 9:37:08 PM > Subject: Re: [swinog] RBL's (again) (Was: Anyone from Green here?) > > Stanislav Sinyagin schrieb: > > > I don't know anything about proper spammers.

Re: [swinog] Anyone from Green here?

by Stanislav Sinyagin

there is at least one reason for not sending email directly: if the server IP address is added to some blacklist like SORBS, the notification is sent to the contact address of the reverse zone. If the server is under the ISP's maintenance, the ISP will (supposedly) notice this event and try its best (haha) to remove the server address from that blacklist. If the end-user's fixed IP address appears in SORBS list, the user will not notice it, and it will take much more time before it's removed. interesting, is there a business case behind? How much would one pay for a reliable and SORBS-free mail relay service? It's actually quite easy to build :) ----- Original Message ---- > From: Per Jessen <per.jessen(a)enidan.ch> > To: swinog(a)lists.swinog.ch > Sent: Thursday, September 11, 2008 12:58:40 PM > Subject: Re: [swinog] Anyone from Green here? > > Stanislav Sinyagin wrote: > > > Anyway, who's going to send email directly from a broadband > > connection, instead of using the ISP's relay? :-) > > > > Provided everything is properly set up, why shouldn't they?
