Hi friends I install Ubuntu 14.4 and Koha 16.5 and install postfix Gmail to send notice and check in and out the email send ok but when I check send all mailing my Gmail I don't show the massage and the email massage not shown to the patron, so how solve that problem
The short version: If you're not sure your sending domain is set up just right, it's likely easier to send via somebody who already has a working setup in place. And gmail.com is far from optimal for testing whether you have a somewhat working SMTP outbound setup. Slightly longer version: Setting up a mail service for a domain so the messages it sends are actually accepted by the world at large used to be simple enough in the early days, but it has become incrementally harder over time. Getting your mail delivered all the way to gmail end users is even harder. Unless you pamper the (g)mail deities just right, their machinery has been known to acknowledge receipt of individual messages but then go on to having messages silently disappear and never reach actual end user mail boxes. The minimum requirements for a domain include * at least two authoritative name servers * valid MX records for the domain * the mail exchangers designated in those MX records need proper reverse lookup In addition, you will need for your own pain mitigation make sure that * you only relay for hosts in your own network(s) * you have content filtering (spam/malware) in place on outgoing as well as incoming, greylisting and friends help too but are not mandatory Further, there's a school of thought that many mail architects and admins subscribe to (including gmail and other heavies) that mandates you set up * SPF records (a DNS TXT item) that specify valid sending hosts for your domain * DKIM records (a DNS TXT item) and make your MXes sign outbound mail * DMARC records (a DNS TXT item) to combine the two plus some additional data such as reporting and to actually deliver to google-hosted domains and gmail most of the time, you will sooner or later need to get them to generate a "google site verification" ID for your domain (you guessed it: another DNS TXT item), mainly because they do not actually trust the much ballyhooed DMARC Rube Goldberg contraption anyway. If you produce too many similar messages (in my case, hourly log summaries), you will see them at random intervals refuse delivery and bounce anyway. There will be other errors and failures, and of course random factors that will interfere and cause issues. Basically, running a mail service is not a trivial task, but if you put the work in to do it right and respond quickly and sensibly to issues as they occur, you will succeed. But it's understandable that a significant subset of those who try just hand it all off to somebody else to handle on their behalf. Hope this helps. - Peter -- Peter N. M.
