Finding Mail Senders

Thu, 17 May 2007

mailsender finds all of the email addresses sending to a given recipient (e.g., joe@here.tld) in one or more logfiles (assumes modern sendmail-style log format with 'sm-mta' lines, etc.) This will not work for any other kind of MTA (e.g., exim, postfix, qmail, etc.)

Usage:

mailsender joe@here.tld /var/log/maillog /var/log/maillog.0.gz ...

or using shell globbing:

mailsender joe@here.tld /var/log/maillog*

Output is the all of the sender email addresses, followed by how many times they attempted to send (which may be exacerbated by greylisting or other temporary failures, etc.):
