I've just gone through complete agony bashing my head against the wall with configuring Postfix and Centos to relay out through gmail. Gmail has kindly (!?!?!?!) put two-factor authentication in place, which means a few tweaks along the way - specifically, the addition on a "single-use" password purely for relaying and the addition of a "yum -y install cyrus-sasl-plain" I'll be happy for someone else to update the main postfix / centos pages, but I think having an article that goes through - soup to nuts style - how to install Postfix + Inbound TLS + SASL Authentication + Outbound GMAIL (+ Anti-spam/Anti-virus when I get to it) as a series of steps would be a good thing. I can write a draft (in fact I am anyway for my own edification) if you wish to see that before commiting to a page. -- Adrian Hall (Personal Account) photoadrian at gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
