There are a few businesses now that offer IP "warm-up" services for mailing list providers. Probably not helpful in this specific instance, but they are good for the large mail providers like gmail that do their filtering with "secret sauce". They basically maintain a fleet of user accounts on all the major freemail providers and send your sample content through your smtp server over a period of a week or so. They also automate interaction with the inbox - including marking it "not spam". Not cheap though... and I have no idea how they justify a business that relies on breaking the AUP of the freemail providers. :) Charles > > -- > [*] sys4 AG > > http://sys4.de, +49 (89) 30 90 46 64 > Schleißheimer Straße 26/MG, 80333 München > > Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 > Vorstand: Patrick Ben Koetter, Marc Schiffbauer > Aufsichtsratsvorsitzender: Florian Kirstein > > _______________________________________________ > Postfix-users mailing list -- postfix-users@postfix.org > To unsubscribe send an email to postfix-users-le...@postfix.org _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
