MxToolbox online Email Header Analyzer


Recommended Posts

MxToolbox frequently mentioned here, thanks to member jay90210 of the Whirlpool forums for highlighting their header parsing tool "This tool will make email headers human readable by parsing them according to RFC 822." which helps with analysis - particularly with relay delays (converts times to common UTC) which might indicate service problems or clumsy forgeries etc.:

Individual analyses can be saved for discussion and/or comparison with SC parsing:

Doesn't choke on IPv6 (doesn't extract/verify host addressing data from it either, but that's not its job):

Anyway, since apparent transmission delays are a fairly frequent query "here" (and some of us struggle with manual time-zone conversions, the back-to-front header sequence, etc.) this little facility may be of use.
