th mail log shows that there i a problem with the authentication of the mail how should i fix that

 

webmail shows the same issue but it is more readable

this is from ispconfig mail.log

Dec 20 11:07:29 ispconfig postfix/smtp[15701]: CD21CC2D23: to=<[email protected]>, relay=gmail-smtp-in.l.google.com[142.250.27.26]:25, delay=0.37, delays=0.09/0.01/0.09/0.18, dsn=5.7.26, status=bounced (host gmail-smtp-in.l.google.com[142.250.27.26] said: 550-5.7.26 This mail has been blocked because the sender is unauthenticated. 550-5.7.26 Gmail requires all senders to authenticate with either SPF or DKIM. 550-5.7.26 550-5.7.26 Authentication results: 550-5.7.26 DKIM = did not pass 550-5.7.26 SPF [inventionsoft.eu] with ip: [192.145.57.188] = did not pass 550-5.7.26 550-5.7.26 For instructions on setting up authentication, go to 550 5.7.26 https://support.google.com/mail/answer/81126#authentication a26-20020a170906369a00b00a1da52812a4si11375615ejc.603 - gsmtp (in reply to end of DATA command))

 

we have added them to the dns of the domains but i still get the same error if i send to gmail and if i sent an email from [email protected] to [email protected] i get the 550 sorry no mailbox here by that name so should i get rid of them in ispconfig or not

 

this is what happens if i do the command netstat -tap | grep 100 this can also be an issue i think

 

I have written a Tutorial on e-mail setup on ISPConfig, link in my signature. Useful reading to get e-mails working.

 

well i can sent to gmail now but cant recievie yet eventhoug the ports for recvieing are open

 

it does arrive

 

@till how do i check if a port is blocked for ispconfig i looked but cant find anything

 

it gives me this how do i fix it in ispconfig
