Email forward mailmaps issue

[fdesfosses]

hi there

i have my domain, desfosses.net, my registrar was domains.google.ca, they sold their solution to squarespace. all is fine EXCEPT they do not have DDNS like google or zoneedit.

SO, i bought one credit, and changed my DNS server from squarespace to zoneedit, all seemed fine, my dns SOA record was showing correctly zoneedit in mxtoolbox web site, i was able to configure my asus router with DDNS DYN entry, all worked, then i was configuring mailrelay/mailmaps... so i want to forward all email going to @desfosses.net be sent to supercrishna@gmail.com. did not worked, i mean, sometimes it did sometimes it did not... tried several DNS entry for MX, i tried LOCAL, and then i tried the same mail thingy MX as squarespace has, which was mailgun (i wanted to have zoneedit, tell MX that it was mailgun, so bypassing zoneedit mailmaps)... it seems i was able to get mail sometimes but not everytime and a few was delayed and such and even some never came in... so i had to revert my change of SOA back to squarespace (disabling zoneedit) for the time being.

as soon as i reverted back, all mail new mail forward came in, using squaresapce, without issue. and even received all the test i made during my zoneedit setup. so mail where stuck somewhere, and once this was changed, they all came in.

i need a little help here! what can i do to provide more info ? best regards.

Hello,

I had our Tier 2 take a look at the issue. According to our logs from yesterday, the messages were leaving our servers successfully and being accepted by the Google servers. However the messages were delayed on their end for some reason. I've provided a log of this below:

those where successful email (the 2 i tested and worked), send from testmail.com... do you see email from mdfcommerce.com !? those where blocked. never received until i changed back to my original provider. those are not comming through and i had also 4 email from @pps-spp.parl.gc.ca that i never redeived.

 

[fdesfosses]

those are my sent items. that never went into zoneedit... so some are almost identical in timestamps, due to dns not being zone edit, some other got delayed, because zoneedit blocked them, so they gone through later with squarespace.

i can, if required, switch my dns back to zoneedit and use mailmaps, and redo those test. to see if its going through.

SENT MAIL FROM OFFICE @mdfcommerce.com as source



this is when i received them on mail local mailbox, i used my work email to sent to my home domain @desfosses.net -> forwarded tu supercrishna@gmail.com (mailmaps)

Hello,

Unfortunately we're not seeing anything hitting our servers from either @mdfcommerce.com or @pps-spp.parl.gc.ca. At this point you'll want to switch back to ZoneEdit servers and try testing the mailmaps again. Note that server changes can take up to 24 hours to propagate so you'll want to make sure to wait before testing.

cool, si i changed back my SOA to zoneedit, left LOCAL as MX, mailmaps configured, mxtoolbox mx lookup points to

and MX wise, this server mx ip is blacklisted on 3 different proviers, which tells me that if senders email are verifying those blacklisters, could be the reason WHY email are not processed.



this might need to be looked at.

 

[fdesfosses]

so i did a test, from both, office @mdfcommerce.com and @sendtestemail.com. sent at the same time.

i received sendtestemail.com right away (view testmail.log), while still waiting on the one from @mdfcommerce.com

my guess, is that mdfcommerce, and the government are looking at these blacklist... probably other senders also look at these blacklisting. nevertheless, i will not switch back from zoneedit, until i get a failed response back. my TTL are 5 minutes, not 24 hours.

which will also or might also turn out to be an issue with other service i can receive email from, for instance, bank, amazon or other important stuff that could look up these blacklist service.

 

[fdesfosses]

received email, from office, outlook.com to zoneedit with more than 20 hours delay. where as not using zoneedit its instantaneous. so i attached both properties of both email. was sent at the same time, one from web portal testmail and the other one from mdfcommerce work email.

when not using zoneedit, when i use squarespace, email delivery is instantaneously. also, this afternoon started to have weird issues with DNS resolving...

google dns servers cannot resolv my dns anymore.


but zoneedit can.


so im switching my dns back to squarespace... there is too much latency with some service, please advise once blacklists are cleared.

best regards!

Hello,

A few things to note:

1. Blocklists are looked up when receiving mail and not when sending. Email providers do not block mail from being sent to a system which is on a Blocklist, only when recieving email.

2. We do not deal with those specific Blocklists as they charge you a fee to be removed. Other Blocklists do not do this.

3. The delay from your TTL and the delay/propagation from a name server change are two different things. When you change your name servers for a domain name there is a 24 to 48 hour delay due to propagation across the Internet. During this time period DNS servers will randomly query either your old servers or your new servers, so they will randomly either get your old MX record or your new MX record. This is why you need to wait for this period to be over before doing any kind of DNS testing as you can get bad results.

4. Our logs still don't show any messages coming from mdfcommerce.com hitting our server (mx-caprica.zoneedit.com). No errors either.

5. Google servers are resolving the DNS for desfosses.net with no issues. For best results we recommend doing an actual dig against the servers you are testing instead of an 'nslookup'.

this is exaclty what i did

and i have my putty log saved to show with the timestamps i did my test. your test showed DNS with another SOA i reverted it back to squarespace.

this screen shot was during dns hosted at zoneedit



this screen shot is right now, hosted by squarespace


i will give it another 48 hours to settle down, then switch SOA back to zoneedit.

since i switched back to squarecepace, all email forward are processed within 2 minutes. was not the case with zoneedit mx servers.
