However, if you know the TCP port used (see above), you can filter on that = xx:xx:xx:xx:xx:xx //In the filter section of packet analysis You cannot directly filter SMTP protocols while capturing. Show only the SMTP based traffic with the 'MAIL FROM' command: contains 'FROM' Display FilterĪ complete list of SMTP display filter fields can be found in the display filter reference Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically. XXX - Add a simple example capture file to the SampleCaptures page and link from here. (XXX add links to preference settings affecting how SMTP is dissected). XXX - Add example traffic here (as plain text or Wireshark screenshot). SMTP uses MIME_multipart to transfer attachments The well known TCP port for SMTP traffic is 25.
