Could you resend with proper line breaks. This is difficult to read.
Sorry, the line breaks got messed up. I'm using OpenSTMPD 6.8 portable and want to filter on DNS names or HELO strings with regular expressions. Therefore I created the following minified config: -------------------------------- $ cat /etc/opensmtpd/smptd.conf table helotable db:/etc/opensmtpd/helotable.db filter block_helo phase helo match helo regex <helotable> disconnect "554 Not welcome" listen on 0.0.0.0 filter { block_helo } $ makemaup -U /etc/opensmtpd/helotable.db myte.t <set> -------------------------------- However the filter "block_helo" only matches when someone connects with the verbatim string "HELO myte.t" (with a dot), which is of course not how regex are supposed to work. As soon as I replace the database entry with a regular text file (table helotable file:/etc/opensmtpd/helotable.txt), the regex starts to work, ie "HELO mytest" or "HELO mytett" are matched. Question: How can I use regular expressions in db files? Text files don't seem to be an option, because they are only read on startup so I cannot update them on the fly.
