Spammers illustrating, well, something
I'm on the general mailing list for Exim and over time I've become used to seeing what I'll call 'please do my homework' requests there. By this I don't quite mean literally requests for this (so far no one seems to assign configuring Exim as homework for some class), but instead requests for help with problems which clearly show that the requester has not attempted to help themselves and is turning to the mailing list as a last resort; instead the mailing list is serving as a first or second resort. This is probably completely normal for any open source software with a decent usage level and I've long since gotten over being particularly irritated about it.
Every so often, though, the mailing list sees an unusually spectacular instance. Such as this recent one:
Working with sending e-mail marketing and I'm using cpanel / whm with exim in its latest version.
Need to optimize the shipping of exim, and to receive e-mail the same now send direct to the recipient, and that was not generating the send queue.
I have noticed that the server is sending queue accumulating and analyzing the logs shipping seems that ISPs are blocking recipients immediate receipt, claiming the high flow of sending e-mail, noting that 100 IPS rotacioando have every referral, this set RDNS, SPF and DKIM,
I suppose I shouldn't be too surprised. (Self-admitted) e-mail marketers need to send their email using something and sometimes they're going to use the same mailer that I do. And some of them are going to ask other people to do their homework without entirely thinking the whole thing through.
(This message was met with a resounding complete silence on the Exim mailing list, which restored a bit of my faith in humanity.)
