SMTP Log

[rranieri]

Hi

pmg is aborting some connections, Is there any way to have a smtp communication log?

for example:

What does PMG write in the journal for such mails? - there will be at least one entry explaining what's happening

Just to be on the save side - PMG (actually postfix+postscreen) does work with a few delays here and there - since this can help detract some spammers - so make sure you do wait a few seconds (up to 1 minute)

timeout after DATA (2279 bytes) from smail.sili.com.br[187.108.198.17]

seems the sending system (187.108.198.17) did not finish sending the mail (during the DATA command) - either a problem with their network setup (or the network setup of your PMG) - or the software used to send the mail has a bug
