Hi all, I'm having a problem sending email to a particular network. We have Exim 4.87 and is working quite well without particular problem.
Lately one of the users noted that he has problem sending to 4 particular domains. I checked it and it appears that all are giving connection timeout. All are hosted on a particular network. Doing an email verification with verify-email.org give back an ok, the destination email is correct. But doing a check with dnsstuff give out a failure with the mail server connection answer: xxx.xxx.xxx.xxx | failed message send with: messaging failure: Time out occurred or Remote server closed connection prematurely and doing a check with mxtoolbox give a warning for the SMTP transaction time SMTP Transaction Time 15.297 seconds - Not good! on Transaction Time I can telnet the mail server and they have exim 4.89 the answer time to telnet is about 19 seconds I'm rather sure that they have cPanel in place with the new tarpitting choice on Introduce a delay into the SMTP transaction for unknown hosts and messages detected as spam But, unfortunately, we have no connection with this network and a first request to them has been refused as we have no active services with them. I tried to put these set in the smtp transport of our exim conf connect_timeout = 10m command_timeout = 5m data_timeout = 5m final_timeout = 10m but they did not help. Question, is there anything I can do (or try) to manage the long initial delay while connecting to this servers ? There should be something as verify-email.org manage to go on and do the recipient check. Thanks in advance for any help you can offer.
