Over the last few days I discussed SMTP delivery problems with a czech site which was using Postfix and a CISCO ASA with "smtp protocol fixup" enabled.
I was able to work around the delivery problems by stripping the DKIM headers on outgoing mails (as so often). Some interesting info got out: I've also discussed these results with local Cisco support and they confirmed it's a known bug (not published) with DKIM and smtp inspection engine in latest IOS versions. This should be fixed in some newer IOS version (8.4(10)) which is not public yet (latest is 8.4(2)). -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de
