In the early hours my phone went off, warning me the rejectlog had
started filling up.
Searching around I see this is a well know issue. Checking the mail I
see the rule triggered was:
## acl/40_exim4-config_check_data
deny
condition = ${if > {$max_received_linelength}{998}}
message = maximum allowed line length is 998 octets, \
(and also the IGNORE_SMTP_LINE_LENGTH_LIMIT above ...does this go in
update-exim4.conf.conf?)
Looking at the actual message , it looks like SPAM that managed to get
accepted by gmail
1208 <img
src="http://url3791.us.khoros-mail.com/wf/open? .....many many
characters of junk
alt="" width="1" height="1" border="0" style="height:1px
!important;width:1px
!important;border-width:0 !important;margin-top:0 !important;margin-bottom:0
!important;margin-right:0 !important;margin-left:0 !important;padding-top:0
!important;padding-bottom:0 !important;padding-right:0
!important;padding-left:0
!important;"/></body>
(this is all on one line, I've wrapped it here)
My cronjobs downloaded the mail (fetchmail) then passed it (to me)
locally via exim4 (SMTP) ... it fails, and we retry later.
So, in this case, I go to gmail.com and using the web interface, delete
the 2 SPAM messages.
This is not always possible with other mail hosts . My main mail gateway
only offers imap, pop etc ... no web interface.
So what is the best way to deal with these kinds of issues?
