Problem with Plus addresses
Im trialling fastmail at moment and i have created a Plus address to try out that option. I sent an email To the plus address from my yahoo account and it got directed into the correct folder on fastmail. But when i tried to send a return email to yahoo from the plus address it gets bounced back. This doesnt happen with the default ie non plus address.
Is this a common problem with the Plus addresses because of the + symbol ???. Does the same thing happen with Subdomain email addresses ??? I dont want to take out a paid subscription if i cant rely on either the plus or subdomain system for alias addresses |

Using plus and subdomain addressing with folder personalities
Welcome to the EMD Forums! I apologize for the very long post, but wanted to fully answer with suggestions to get the folder addressing working properly. This will work fine once you get the settings correct.
Fastmail is very reliable, and plus addresses work for most other services. I use subdomain aliases instead, because I can't remember any service which rejected them and I like the look of a subdomain address. I just tried a test from Yahoo to a Fastmail plus and subdomain address, and they both worked when I replied, with the replies arriving properly in my Yahoo test account. Yahoo is not always reliable when sending or receiving, so it may take several minutes for messages to/from Yahoo to get delivered. When you say the reply (from the message sent to the plus address) bounced, what exactly happened? If you go back to that folder, open the original message received from Yahoo, and click Reply, here is what should happen:
The personality (From address when you send a message) is also affected by the Settings > Preferences (at left) > Advanced (at upper right) > Account Preferences screen.Things can get complex when determining the correct personality to use when replying, so I recommend you set the From when replying setting to Always default folder/main. Be sure to Save your settings when you make a change. You can then use the Settings > Preferences (at left) > Advanced (at upper right) > Folders screen to force the Default personality for that folder to the one you set up for the plus address. When all of this is set up, incoming mail to the plus address will be filed in the proper folder, and replying to that message from that folder will cause the plus personality to be used and place the plus address in your From field (rather than your main email address). My guess is that you are somehow getting a malformed From address which is preventing the message from being sent. Look over my suggestions and I'm sure it can be resolved. The complex part is getting the replies to use the plus address (or subdomain address) rather than your main account address. It takes several steps, but you can set this up so that different folders act like different email accounts, with specific email addresses used for each folder. Once you understand subdomain addressing, I think it's easier. You can put anything to the left of the @ (such as a folder name or anything else), and to the right of the @ you use your main login username followed by a period (.) then the domain. So if your login address is jcitizen@sent.com, you can use subdomain addresses such as: folder12@jcitizen.sent.comIf the folder "folder12" exists, the first address will deliver into that folder. If that folder doesn't exist, the message will be delivered into your main Inbox. If the folder "banks" containing the subfolder "BOA" exists, the second address will deliver into that subfolder. The case of the folder names and case in the email address is ignored. If that subfolder doesn't exist, the that message will file into the "banks" main folder. Another advantage of using such subdomain or plus special addresses is that you know that messages with these odd addresses are nearly positively from your bank, since nobody else knows this oddball address.

Plus or Subdomain-Adressing for Sent Items
Hi Bill
If I want to send a bcc from my personality to be placed in the 'Sent Items' Folder of another FM-account I have access to: how can I achieve that? |

You can tell your personality to send a bcc to the address username+sent_items@fastmail.fm (or whatever domain), and it will be placed in his "Sent Items" items folder. The separator is the underscore character.

That is an excellent explanation of sub-domain addressing. I have never used it but may give it a whirl. However, unless Fastmail is also taking care of DNS for the private domain, I don't see how it would be possible to use sub-domain addressing with private domains (perhaps with wild card MX RR?). Does FM permit sub-domain addressing for private domains? Thank you. -- Jacinto |

For private domains, it might depend on how you enter MX servers at your supplier, unless you have nameservers set to Fastmail.
For example, I use Godaddy for my private domain. I leave my nameservers at Godaddy, not Fastmail. At Godaddy, I enter * (asterisk) in the Host field as a wildcard for all subdomains that do not have an explicit MX server different from Fastmail. In the Points To field, I of course enter in1-smtp.messagingengine.com at priority 10, and (separate line) in2-smtp.messagingengine.com at priority 20. It works for me. Godaddy uses @ in the Host field to set the primary domain MX. |

As Lane said, you need to enable subdomains with a wildcard (or you could enable only specific subdomains). If you are using the Fastmail Custom DNS feature this is automatic.

I took a look at the "Virtual Domains" page and saw the option to allow (or not) sub-domain addressing. DNS for most of my domains is not hosted by Fastmail. This would mean that I would have to publish MX records for each sub-domain or a wild card record. Although it piqued my curiosity when I first read Bill's explanation, now that I have thought about it, sub-domain addressing may not be such a good idea because it has one major drawback: you are exposing more possible Spam targets to the Internet. I think I'll pass. Thank you all. -- Jacinto |

I guess you have been lucky with the spambots. In my experience with business mail, I receive Spam daily. Part of the problem is legitimate ignorant businesses, including some very large ones who CC 500 or a 1,000 recipients on one message. Some mail hosts will not accept delivery of them with that many recipients, unfortunately, Fastmail does (at least the last time I received one of them). Once one of the infected recipients has my E-Mail address, I'm added to the Spam recipients list. If I get the gist of what you've said about the use of sub-domain addressing, you use the local part temporarily until it becomes a Spam target or is no longer needed. -- Jacinto |

Bill should confirm, of course, but I suspect what he does is give a unique address to each business, maybe something of the form business@sub.mydomain.com. If that gets compromised, then it is only necessary to disable that one address, and change it at that company to something else. It would be very unusual to get spam sent to random addresses at a subdomain, though I have experienced it commonly at the main domain.

Details about use of subdomain addresses
Yes, lane correctly expressed my situation. Let's say that I want to give my bank an email address to contact me and I have a Fastmail domain alias such as johndoe@fastmail.fm or a Virtual Alias at my own Virtual Domain at janedoe@mydomain.net.
Sorry that description took so long! This system works well for me and has allowed me to discover that a service had a security breach which released my subdomain address to spammers. I informed the company (which did not know about the breach until my message) and told them to use a new unique subdomain address. Bill Last edited by n5bb : 23 Nov 2013 at 11:34 AM. |

Unfortunately it seems that the vast majority of online organisations are ignorant of RFC2822 (the standard which defines, amongst other things, what constitutes a correct email address) and thus erroneously regard several characters (most commonly including plus and apostrophe) as being "invalid" in an email username. It's been reported here on EMD that there was (is?) at least one organisation which reckoned that an email address is "invalid" if the domain part has more than three fields! (Which of course is nonsense, and means that email from a domain such as joecitizen.fastmail.co.uk (four fields) would falsely be rejected; a valid domain could probably have as many as 32 fields, although they would have to be one character each to fit within the 64-character limit.)

Because AE was replacing the plus character with whitespace and I wasn't receiving its mail, I had to change the '+' to a '.' to be able to receive it. Considered complaining about it to AE but decided not to waste my time in what would end up being a quixotic exercise in futility. -- Jacinto |
