You indicated that you are attempting to connect your iPhone to SmarterMail 12.1 using IMAP.
The most current version of SmarterMail is 12.4.5364
The fixes and patches in subsequent versions of SmarterMail, since 12.1, include:
- CHANGED: IMAP commands are no longer returned in all caps.
- CHANGED: IMAP Retrieval now sends the password in quotation marks.
- FIXED: The IMAP fetch query for a message's envelope now correctly handles email addresses that contain quoted user name parts such as "user name"@domain.com.
- FIXED: The IMAP ENVELOPE command response now correctly escapes quote characters when returning the subject value.
If you are not the SmarterMail server operator, then you will need to contact your provider to let them know they need to install the upgrade to help eliminated IMAP issues.
You should also consider the use of port 587 in lieu of port 25, when setting up your account(s). In their efforts to fight spammers, many internet transport providers block port 25 for client to MX server communications.
The following ISPs, both in the USA and around the globe, are known to block all device to MX server traffic on port 25:
- People PC
- All Japanese ISPs
- France Telecom/Orange
The alternate port, 587, is now mandated as a MUST BE OPEN port on all MX servers by the IETF.
