Hi, I have just completed a simple test. First I created a domain with MX set to the same IP as the currently gmail troubled server. I've tried to sent mail from gmail and some other providers and all except gmail went through OK. Then I created new domain with MX set to another IP but connected to the same router/firewall and the same Xmail server. Mail sent from gmail did come through without any problem.
It seems to me that google or some firewall they use somehow blacklisted the first IP. I think it was because a clients domain had expired and after realising that, they also managed to enter 2 MX records in DNS with one pointing to the non existent mail server. Both domain and DNS are as they should be for more then a week now. We have now sent that information to the google mail support staff and are still waiting for the answer. I will let know if that solved that issue. Matic CLEMENT Francis pravi: Xmail does not do any 'callback' to verify sender email ... (The only way to do this is from a filter. And in any cases currently xmail first possible filter execution is AFTER 'RCPT TO' smtp command, not just after HELO/EHLO command. The only internal filtering in xmail is on ip address at connection from spammers.tab, ipprop.tab, ... files) The Google/Gmail staff response seems to be unapproriate for the present problem :( Did you do some network analysis on both sides of your firewall to see if gmail servers really try to connect to you and where in the process of the connection it ends exactly ?

Please contact the recipient's webmail provider and ask them to whitelist Gmail from callback verification. Callback verification is a technique used by SMTP software thatattempts to open a new connection to any server that it doesn't recognizewith a blank message. Because these attempts to verify sending addresses can happen very frequently, traffic may appear as a Denail of Service attack, which will prompt Gmail servers to block these messages. Gmail does not support sender verification, and suggests that other webmail providers adopt SPF or DomainKeys instead. ------------------------------------------------------------------------ --------------- What the heck do they mean by this? Xmail doesn't support callback verification, does it?

Can you try without glst? I don't fing glst is the problem here as : 1 - glst is not 'runnable' until "MAIL FROM" and "RCPT TO" are received = (it needs a 'triplet' to do correct work) 2 - and in any cases, if glst returns a 'drop' code to xmail, then a = line will appears in the smtp logs with ERR=3DEFILTER But here Matic says 'no linein xmail logs at all' for this connection. Same case if ip in spammers.tab file, xmail logs the action in smtp = log. I think the problem is not xmail nor any filter after xmail.
